War in Ukraine: Current Threats to Radiation and Nuclear Safety of the Country
On 24 February, at 5 am, Ukrainians woke up to the sound of explosions: the Russian Federation had begun a war against Ukraine. Today’s realities of Ukrainians are disturbing sirens, basements and bomb shelters, sounds of shelling and explosions, destroyed houses, hospitals, schools… Tanks, armored personnel carriers, Bayraktars, Grad missiles, armored combat vehicles, air defense, anti-aircraft missile systems, fighter jets belong to the everyday vocabulary of ordinary people. The Armed Forces of Ukraine, the territorial defense, the foreign legion are heroically defending our state. All the inhabitants of Ukraine have united: some of them join volunteering, some people help financially, some join countering fakes and protecting information, and some people stops tanks with their bare hands. The whole world opposed the war in Ukraine and supports our state!
Every day, Russian troops strike at military and civilian targets. What is the situation in the nuclear industry of Ukraine? Is there a threat to the radiation and nuclear safety of Ukraine?
Chronology of events in the nuclear industry during the war in Ukraine
According to IAEA experts, Zaporizhzhya NPP unit 6 was transferred into cold shutdown, after which tests were carried out to assess fuel assembly cladding integrity. The results showed that claddings were not damaged. The transfer to cold shutdown will allow testing of the primary and secondary cooling systems and pumps at Zaporizhzhya NPP. Unit 5 remains in hot shutdown for in-house loads.
There was an explosion near the turbine hall of Zaporizhzhya NPP unit 4. Ukrainian nuclear scientists who continue their work at ZNPP heard the sounds of the explosion. The russian occupiers said that it was their mine that detonated, but they immediately began to “calm down” the workers and hide the traces so that the IAEA experts would not see this.
In temporarily occupied Enerhodar, the russian invaders are mining the coastline and the territory near Zaporizhzhya NPP. The mayor of Enerhodar Dmytro Orlov announced this.
The invaders are installing an additional fence to protect the entrances to Zaporizhzhya NPP. Thus, the invaders are actually expanding the closed perimeter around the plant, as if they are preparing it for defense. Workers will no longer drive directly to Zaporizhzhya NPP, as it has always been, but will have to cover the part of their way on foot.
According to the IAEA, anti-personnel mine exploded behind the fence near Zaporizhzhya NPP.
According to NNEGC “Energoatom”, in the evening masked occupiers broke into one of the premises in the temporarily occupied Zaporizhzhya NPP and took away four employees of the plant’s physical protection service. The nuclear workers were taken away in an unknown direction, and their place of staying remains currently unknown. At the same time, the company noted that the kidnapped workers were considered loyal to ZNPP occupation management, since they signed contracts with the fake Zaporizhzhya NPP operating organization. In particular, among the detainees was the deputy head of the service Mark Volkov, who contributed in every possible way to the illegal activities of the invaders, according to the company.
IAEA Director General Rafael Grossi arrived at Zaporizhzhya NPP. This is the second visit of the IAEA head to ZNPP, since it was occupied by the russian military. During the visit, Rafael Grossi plans to see how the situation at Zaporizhzhya NPP has changed, communicate with the operating nuclear workers, and act as a guarantor of the rotation for members of the Agency’s permanent mission, which has been working at Zaporizhzhya NPP since September 2022.
russia and Belarus agreed to place tactical nuclear weapons on the territory of the Republic of Belarus. This was stated by russian president vladimir putin. In addition, according to putin, russia has already helped in transforming ten Belarusian aircrafts for using tactical nuclear weapons, as well as transferred Iskander missile systems that can carry such charges to Minsk.
British Deputy Minister of State for Defense Annabel Goldie said that the UK will transfer to Ukraine not only Challenger 2 battle tanks, but also shells with depleted uranium for them.
This information contributed to the emergence of a new wave of nuclear threats from russia, if Ukraine would receive such ammunition, as well as to the dissemination of fake information on the spread of “dirty nuclear bombs”. In particular, vladimir putin announced russia’s readiness to respond if Ukraine would use depleted uranium shells, and dmitry medvedev confirmed in his address that “the threat of a nuclear conflict has increased”, and “every day the supply of foreign weapons to Ukraine brings a nuclear apocalypse closer”.
After the seizure of the Zaporizhzhya nuclear power plant in March last year, russians illegally gained access to classified information subject to export control by the United States. This is a criminal offense under US law according to the letter from the U.S. Department of Energy’s Nuclear Security Administration dated 17 March 2023. Resulting from this document, the russians particularly gained access to two elements: to the Advanced Node Code (ANC-H) of Westinghouse Electric Corporation, which is a three-dimensional code of the reactor core simulator with two power groups, and to 3KEYRELAP5-RT, which is an advanced code for thermal-hydraulic modeling of the reactor. It is used to control and monitor simulators, as well as speed up the processes of simulating various situations at the plant.
According to the General Staff of the Armed Forces of Ukraine, the occupiers began to transfer simulation equipment from the training center at Zaporizhzhya NPP, which was used to improve personnel skills.
The last communication line of the occupied Zaporizhzhya nuclear power plant with the Ukrainian energy system was disconnected because of russian rocket attacks at 03:53 AM in the night. At present, the plant is de-energized and has switched to blackout mode for the sixth time during the occupation, units 5 and 6 are being transferred to a cold state, 18 diesel generators have been switched on to power ZNPP’s in-house loads.
The Energoatom official telegram channel published information at 16:53 PM that after a ten-hour blackout caused by enemy shelling at the largest nuclear power plant in Ukraine and Europe, the line was repaired; switching from standby diesel generators is under implementation in order to power in-house loads from the unified energy system of Ukraine.
At the meeting of the IAEA Board of Governors, Director General Rafael Grossi spoke of an increase in the number of military formations at ZNPP over the past few weeks: “Our team at the plant reported an increase in hostilities near the enterprise. There is an open discussion about the offensive and counter-offensive near the object. My simple question is: are we waiting for a nuclear emergency before we react?”
On 2-3 March, IAEA inspectors were rotated at Rivne, South Ukraine and Khmelnytsky nuclear power plants. IAEA international specialists should monitor compliance with the safety indicators at Ukrainian NPPs, in particular, in a state of war. In addition, IAEA inspectors can analyze the impact of russian military strikes on the energy infrastructure of Ukraine and convey this information to the entire world community.
In its statement proclaimed after the OSCE Permanent Council meeting in Vienna, the European Union expresses “deep concern over the recent explosions near Zaporizhzhya NPP and russia’s continued illegal occupation and control over the object. The situation can be resolved only through the complete withdrawal of russian troops and military equipment from the territory of the plant”.
The rotation of IAEA experts took place at Zaporizhzhya NPP. It was planned in early February, but was blocked by the occupiers.
president of the russian federation dictator vladimir putin signed a law ending russia’s participation in the Strategic Offensive Arms Treaty (START III). This law came into force from the date of its official publication.
IAEA experts reported that about 20 “detonations” were heard during the day, apparently near the plant that is located in the front zone of active hostilities.
IAEA experts reported that 330 kV backup power line was disconnected due to the sound of military activity, then it was briefly restored, but further it was lost again. The disconnection occurred on the other side of the Dnipro River opposite ZNPP. The power line was restored on Sunday afternoon.
Secretary General at the Federal Ministry for European and International Affairs of the Republic of Austria, Peter Launsky-Tieffenthal, in his speech at the special session of the UN General Assembly in New York during the consideration of the resolution “Principles Underlying a Comprehensive, Just and Lasting Peace in Ukraine” stated: “One of the aspects that Austria strongly condemns are the veiled but easily recognizable threats to use nuclear weapons repeatedly made by russia. Nuclear risks are now the highest in last decades and their potential devastating global humanitarian and environmental consequences are a direct threat to the entire international community”.
According to NNEGC “Energoatom”, the russian security forces and Rosatom employees continue to turn Zaporizhzhya NPP into a military base. They set up a machine-gun position on the roof of unit 5, and placed checkpoints at all entrances to clean overpasses, through which personnel get directly to the units. At the same time, more than 600 mobilized personnel and cadets from russia arrived at ZNPP and were placed in the NPP bomb shelter. In addition, the occupiers continue to build fortifications and military installations around the NPP units and dry for spent fuel storage facility (DSFSF).
According to the IAEA, the russian military is blocking the rotation of IAEA personnel at Zaporizhzhya NPP.
The Main Intelligence Directorate of the Ministry of Defense of Ukraine confirms the preparation of components of the strategic nuclear forces for the launch of sea- and land-based ballistic missiles, as well as air-launched cruise missiles. In addition, the Monolith centralized combat control system of the russian federation was tested as part of the preparations for the exercises. In particular, combat control channels were checked, the forces and means of the strategic nuclear forces were transferred to the highest levels of combat preparedness, the crew of the strategic missile submarine was given a combat order to enter the launch area, and 24-hour combat preparedness of the strategic nuclear forces for its use is maintained. In addition, an auxiliary control point of the long-range aviation command was deployed at the Tambov airbase.
Two enemy cruise missiles were recorded during another massive russian missile attack at South Ukraine nuclear power plant at 08:25 and 08:27 AM. Air objects moved along the channel of the Pivdenny Buh River in the direction of the city of Pervomaisk in Mykolaiv oblast, and flew dangerously close to the nuclear facility. The threat of getting into the reactor with possible consequences – a nuclear catastrophe – was high again.
The Norwegian Intelligence Service (NIS) informs in its annual report that ships of the russia’s northern fleet started to go to sea with tactical nuclear weapons for the first time in 30 years.
Today’s russian missile attack on Ukraine’s energy infrastructure facilities, which caused instability in the electric grid, led to the shutdown of one of the Khmelnytsky NPP units. This event was confirmed by IAEA, which stays at NPP. After the incident, all KhNPP safety systems are operated in regular mode. The massive russian missile attack also led to a decrease in electricity generation at the Rivne and Pivdennoukrainsk NPPs.
SNRIU has limited the validity of licenses for the operation of units 3, 4, 5, 6 of the temporarily occupied Zaporizhzhia NPP due to incompliance with nuclear and radiation safety requirements. In particular, we are talking about the location of russian military equipment and weapons on the NPP territory, damage of communication lines with the energy system of Ukraine, and shelling of the ZNPP site. In addition, the NPP downtime and shutdown of all its power units caused a constant gradual degradation of systems and equipment. The decision to renew the license terms will be made by the regulator after ZNPP de-occupation, its return under the control of the legal operator – Energoatom, as well as inspection and restoration activities.
The city chairman of Enerhodar, Dmytro Orlov, said that in the temporarily seized Enerhodar, cases of kidnapping of NPP workers who refuse to sign contracts with the fake rosatom’s company have recently become more frequent.
Personnel from the Kalinin NPP arrived at the temporarily occupied Zaporizhzhia NPP, including reactor control engineers, shift supervisors, electricians and other representatives of the nuclear specialties. The invaders believe that nuclear experts from russia will be able to work at the captured Ukrainian plant.
The IAEA permanent mission working at the site of the temporarily occupied Zaporizhzhia NPP, which is the largest nuclear power plant in Europe, recorded a decrease in the water level in the Kakhovka reservoir.
russia again threatens to use nuclear weapons. So, during a speech in Volgograd in honor of the 80th anniversary of the Battle of Stalingrad, russian president vladimir putin again hinted at the use of nuclear weapons in response to the “threats” of the West saying that Russia “has something to answer” to European countries and added that for those who plans to defeat Russia, “this will not end with the use of armored vehicles.”
Due to the russian occupiers, the full-scale simulator (FSS), which is used to practice the skills necessary for working at a nuclear facility, is not operated at the Zaporizhzhia NPP. The occupiers are deliberately blocking access to the workplaces for FSS instructors, as they refused to cooperate with the enemy and sign contracts with the fake Zaporizhzhia NPP Operating Organization JSC. Training and skill improvement at FSS is an important component of operational activities for NPP safety and should be carried out systematically so that the personnel maintain and develop previously acquired skills. Since the full-scale simulator cannot fully function now, Ukrainian nuclear experts cannot study or improve their skills for an unknown period, and this threatens the operational safety of the Europe’s largest nuclear facility.
IAEA experts at Ukrainian ZNPP report on massive explosions occurred outside the facility. Eight strong explosions were heard. They caused vibration of the offices’ windows at the plant.
According to the Energoatom telegram channel, the occupiers do not have enough personnel at ZNPP. Accordingly, the invaders have reached the point where they are looking for experts in ads. Moreover, they are looking for personnel of a highly specialized nuclear professions: operators of the reactor compartment, operator of the internal combustion engine, experts on the maintenance of reactor and turbine equipment. All these specialties require specialized education and experience, without which it is simply impossible to work at the largest nuclear power plant in Europe. However, the occupiers are only concerned about the number of personnel, and the quality seems to be out of the question.
An IAEA permanent monitoring mission launched its work at the Chornobyl NPP.
An IAEA permanent monitoring mission launched its work at the Rivne NPP.
An IAEA permanent monitoring mission launched its work at the Pivdennoukrainsk NPP. The IAEA permanent presence in Ukraine was expanded to reduce the risks of a nuclear accident or incidents, as well as to control nuclear safety, security and physical protection at Ukrainian nuclear power plants, which are on the part of the russian federation in the full-scale war.
Yesterday, ZNPP’s only 330 kV standby line, which was switched off many times in recent weeks, was disconnected for several hours for maintenance. Now it is connected again. NPP, at which six reactors were shut down, continues to receive off-site power for nuclear safety functions from the last 750 kV transmission line remaining in operation.
Air attacks caused a fire on the premises of the Institute for Nuclear Research in Kyiv. The fire affected a warehouse at the site and caused no damage to the reactor or to its fuel. No personnel were injured. Radiation monitoring was performed, and radiation levels were confirmed to be normal.
russian occupiers continue to exert moral and physical pressure on ZNPP workers. Thus, almost 1500 employees of the Zaporizhzhia NPP, who refused to receive russian passports and sign a contract with the rosatom, are deprived of passes and access to the enterprise. The invaders look for new NPP workers in russia and prepare a housing stock for future workers through the so-called nationalization of the apartments of the departed local residents.
In Enerhodar, Zaporizhzhia region, the russian occupation forces forced about 3000 workers at the Zaporizhzhia NPP to obtain so-called russian passports. This is stated in the message of the General Staff of the Armed Forces of Ukraine.
In the evening, backup power supply of the Zaporizhzhia nuclear power plant was restored after repairing the 330 kV line, which was disconnected on New Year’s Eve due to damage caused by shelling, was completed.
The IAEA mission reported on exhaustion and stress among ZNPP operational personnel. It is noted that the alarming level of fatigue of NPP workers is due to the increase in the length of the working day and additional shifts, as well as stress caused by the war.
In the temporarily occupied Crimea, equipment and military of the russian radiation, chemical and biological protection were located at the Crymskyi Tytan plant in Armiansk. It is not yet known what caused the presence of these units at the captured enterprise. The presence of the military at chemical industry objects is a violation of international humanitarian law.
The russians are bring their personnel to the captured Zaporizhzhya nuclear power plant instead of those who refuse to work for the occupiers. Thus, in January, it is planned to appoint dmitrii meniaev, deputy director of the special safety department of the rosenergoatom concern (rosatom subsidiary), to the position of ZNPP Deputy Director for Physical Protection and Regime.
occupying energy operator rosatom is implementing its own monitoring system on the territory of the captured Zaporizhzhia NPP, in particular, a closed local network, video surveillance systems, etc.
IAEA experts reported that at 21:35, the Zaporizhzhia NPP was disconnected from the 330 kV Ferosplavna-1 backup line as a result of damage caused by russian shelling on the other Dnipro side, the extent of the damage is still unknown, but repair of the line is already ongoing. At the same time, it is noted that Ferosplavna-1 was the last ZNPP operating backup transmission line.
At 00:46, a Shahid kamikaze drone was recorded flying over the Pivdennoukrainsk NPP in proximity to the nuclear facility, which is an unacceptable violation of nuclear and radiation safety.
russians continue to put pressure on the workers of the temporarily occupied Zaporizhzhia NPP forcing them to sign contracts with the fake Zaporizhzhia NPP Operating Organization JSC or another rosatom enterprise. The occupiers spread fake information that from 1 January 2023, the Energoatom will stop paying salaries to ZNPP employees, including those who cannot get to work places because russian security forces prevent access to them.
IAEA Director General Rafael Mariano Grossi and Ukrainian Prime Minister Denys Shmyhal have agreed that the International Atomic Energy Agency will ensure the continued presence of nuclear safety and physical protection experts at all nuclear power plants in Ukraine as part of an intensified effort to help prevent a nuclear catastrophe due to the full-scale russian invasion of Ukraine.
One of the Energoatom VVER-1000 power units was disconnected from the grid to eliminate faults of the backup protection current transformer. The faults were eliminated, and on 11 December at 02:43, the power unit was connected to the power grid again. The repair of another VVER-1000 power unit, which was damaged as a result of shelling of the Ukrainian energy infrastructure on 23 November 2022, is also being completed. In the coming days, it will also be connected to the grid.
IAEA experts completed work at the Pivdennoukrainsk, Rivne and Khmelnytskyi NPPs. From 29 November to 9 December, they assessed the state of nuclear and radiation safety and security of nuclear power plants under the military aggression of the russian federation. They also checked the physical protection system, emergency preparedness and response, as well as logistics and communications.
At the Zaporizhzhia NPP, the russian occupiers continue to use physical violence forcing workers of the temporarily occupied Zaporizhzhia NPP to sign contracts with the fake Zaporizhzhia NPP Operating Organization JSC or another rosatom enterprise. In particular, the russian security forces broke into the rooms where the ZNPP Social Programs Department was located and severely beat Head of the Department, Oleksii Trubenkov, and his Deputy, Yurii Androsov. After a severe beating, the invaders took them out of the room and away in an unknown direction. In addition, the occupiers detained and “threw to the basement” ZNPP shift supervisor Kostiantyn Beiner, who is a licensed person and is directly responsible for nuclear and radiation safety.
According to the Energoatom, the russian military brought several Grad multiple launch rocket systems (MLRS) to the territory of the captured Zaporizhzhia NPP. The invaders placed these weapons near unit 6, next to the territory of the NPP dry spent fuel storage facility, where some protective structures were previously secretly built violating all nuclear and radiation safety conditions.
Zaporizhzhia NPP in-house power supply is provided from the Ukrainian energy system. All diesel generators are disconnected and transferred to the standby mode. Startup operations are conducted at units of the Rivne, Pivdennoukrainsk and Khmelnytskyi NPPs. During the day, when the power system is prepared, units of these NPPs will be connected to the grid.
On 22-24 November 2022, an IAEA mission took place at the Chornobyl NPP and Centralized Radwaste Management Enterprise. In particular, IAEA representatives visited the Pidlisnyi and Buriakivka radioactive waste disposal sites, CRME Vektor, and ChNPP laboratories. Based on the mission results, IAEA representatives studied the state of the facilities of the enterprises to provide the necessary assistance, namely, upgrade of ChNPP and CRME technical equipment.
As a result of frequency decrease in the energy system of Ukraine, scram was actuated at the Rivne, Pivdennoukrainsk and Khmelnytskyi NPPs, due to which all power units were automatically disconnected. The radiation background at the NPP sites and nearby areas has not changed, all indexes are normal. The temporarily occupied Zaporizhzhia NPP, which is not operated since September of this year, was transferred to a complete blackout mode with the launch of all diesel generators. Thus, for the first time in the 40-year history of the Ukrainian nuclear power industry, all nuclear power units were disconnected.
The russian military shelled the Zaporizhzhia NPP site all morning, due to this, at least 12 hits were recorded. As a result, overpasses for connection with special buildings, chemically desalted water storage tanks, steam generator blowdown system, auxiliary systems of one of the two general plant diesel generators and other equipment of the NPP infrastructure were damaged. Three hits were also recorded in the area of the Raiduha substation. The information about damage and destruction there is still being clarified.
The IAEA Board of Governors adopted the third resolution since the start of the war in Ukraine calling on Russia to stop all activities at Ukrainian nuclear facilities. The document notes: “(The Board) expresses its grave concern that the russian federation did not heed the Board’s calls to immediately cease all actions against and at nuclear facilities in Ukraine and requests that the russian federation do so immediately.” Also “(the Board) expresses its deep concern due to the unacceptable pressure and detentions of Ukrainian operational personnel at the Zaporizhzhia NPP, as well as repeated disruptions in external power supply due to shelling of the adjacent territory.” 24 countries of the IAEA Board of Governors voted for the resolution. Two states – China and russia – voted against, seven – Kenya, Namibia, India, Pakistan, Saudi Arabia, South Africa and Vietnam – abstained, and two more were absent during the voting.
SSTC NRS experts, as crew members of the RanidSONNI mobile radiological laboratory, conducted a radiation survey in the Nemishaieve territorial community, namely, place where the russian military stayed between the Mykulychi and Myrotske villages, Bucha district, Kyiv region, as well as the territory of the park and streets in Klavdiievo-Tarasovo in accordance with the request of local residents. The survey was carried out to identify radioactive contamination and radioactive materials that could be taken by the occupiers beyond the Exclusion Zone and the Zone of Unconditional (Mandatory) Resettlement. According to the results, no radioactive contamination was found, which could be associated with the activities of the occupiers. In the surveyed areas, no increase in the ambient dose equivalent of gamma radiation (EDR) was recorded. EDR values measured during vehicle gamma survey and manually were up to 0.12 μSv/h, which corresponds to the background values peculiar to the area.
As a result of russian missile attacks on the energy infrastructure of Ukraine, the Khmelnytskyi nuclear power plant lost access to the grid and was temporarily transferred to diesel generators as a backup power source. During this period, two NPP reactors were shut down. More than nine hours later, at 3:45 a.m., NPP resumed off-site power through two standby 330 kV transmission lines, and the diesel generators were disconnected. Approximately another hour later, one of these lines was lost again and was restored only at 11:25. Two reactor units remained in shutdown mode.
There was also an automatic shutdown of one RNPP unit due to the loss of connection with one of its 750 kV power transmission lines. As a result, NPP reduced its power, and one of its four units was automatically disconnected. On Wednesday, at 4:00 am, NPP increased power of its another unit to continue power supply to the Ukrainian grid.
In the period from 8 to 11 November 2022, SSTC NRS experts, as crew members of the RanidSONNI mobile radiological laboratory, conducted a radiation survey in the Makarov territorial community. The survey was carried out to identify radioactive contamination and radioactive materials that could be taken by the occupiers beyond the Exclusion Zone and the Zone of Unconditional (Mandatory) Resettlement due to a violation of the radiation safety regime. According to the results, no radioactive contamination of objects, rooms and sites was found, which could be associated with the occupiers’ activities. In the surveyed areas, no increase in the ambient dose equivalent of gamma radiation (EDR) was recorded. EDR values measured during vehicle gamma survey and manually were up to 0.18 μSv/h, which corresponds to the background values peculiar to the area.
At about 22:00, 750 kV power supply at all six ZNPP units was restored, and eight operating emergency diesel generators were disconnected and switched to the standby mode.
After completing an inspection of three locations in Ukraine, which was carried out at the request of the Ukrainian government, IAEA inspectors found no evidence of illicit nuclear activities and materials. Recall that earlier the minister of defense of the russian federation serhii shoigu said that Ukraine was allegedly preparing a provocation against russia using the so-called dirty nuclear bomb.
As a result of shelling by the russian military, the last two high-voltage communication lines of the Zaporizhzhia NPP with the Ukrainian energy system were damaged. At 23:04, NPP was transferred to a complete blackout. All 20 diesel generators were connected, but only 9 of which were left in operation. Units 5 and 6 were transferred to a cold state. Fuel for the operation of diesel generators under ZNPP complete blackout is enough for 15 days.
The Ukrainian ZNPP personnel resumed heat supply in Enerhodar. Hot water also appeared in residential buildings. This became possible after the transfer of two NPP units to the hot shutdown. Now ZNPP employees continue to launch systems to restore heat supply in Enerhodar. Water temperature is currently 51 degrees Celsius. This is not enough to provide Enerhodar with heat and hot water in full. However, even this temperature helps protect the city’s utility networks against damage under cold weather. Since May, Zaporizhzhia NPP, and not Zaporizhzhia TPP, has been supplying heat and water to Enerhodar residents. It had to be shut down due to the terrorist actions of the russian occupiers.
russian occupiers placed electronic warfare systems on the roof of ZNPP unit 5. This was reported by the Main Directorate of Intelligence of the Ministry of Defense.
In the evening, beyond the fence along the ZNPP perimeter, a land mine exploded, which led to the disconnection of a 750 kV external power line. As a result, the ZNPP-4 power supply line was disconnected. This was announced by IAEA Director General Rafael Grossi.
Within three days, SSTC NRS as crew members of the RanidSONNI mobile radiological laboratory conducted a survey in the Ivankiv and Polissia territorial communities. The survey was carried out to identify radioactive contamination and radioactive materials that could be taken by the invaders beyond the Exclusion Zone and the Zone of Unconditional (Obligatory) Resettlement due to a violation of the radiation safety regime. According to the survey results, no radioactive contamination of objects, rooms and sites was found, which could be associated with the activities of the occupiers. In the surveyed areas, no increase in the ambient dose equivalent of gamma radiation (EDR) was recorded. EDR values measured during vehicle gamma survey and manually were up to 0.19 μSv/h, which corresponds to the natural background values peculiar to the area.
During the week, the russian occupiers have been conducting unauthorized construction on the territory of the dry spent fuel storage facility (DSFSF) at ZNPP. Ukrainian personnel and IAEA representatives at the ZNPP site are not allowed by the invaders to enter the construction site. Such construction on the territory of a nuclear power plant is an illicit interference by russia in the ZNPP design and a gross violation of both the terms of the license for NPP operation and international nuclear and radiation safety requirements. 173 containers are stored at DSFSF. The destruction of these containers due to detonation will lead to a radiation accident and radiation contamination of several hundred square kilometers of the adjacent territory.
G7 called on Russia to return full control of the Zaporizhzhia nuclear power plant to its rightful sovereign owner, Ukraine, remove all russian personnel from the facility, and stop any reckless and hazardous attempts to bring ZNPP under russian control, which could further aggravate the threat to its safety.
At the meeting of the First Committee of the UN General Assembly, the deputy head of the russian delegation, kostyantyn vorontsov, said that russia excluded the established of a demilitarized zone around the Zaporizhzhia NPP because this would create conditions for a counterattack by the Armed Forces of Ukraine.
russian terrorists once again shelled critical infrastructure substations on the territory controlled by Ukraine. This caused disconnection of the last 750 kV ZNPP–Dniprovsk line at 03:59. In the transitional process, because of short-term voltage drop, the ZNPP inhouse transformer tripped and diesel generators actuated. In addition, the 750 kV Pivdennoukrainsk NPP–Dniprovsk line disconnected, but without affecting the PNPP loads.
russians detained and took Oleg Kostyukov, Head of ZNPP Information Technology Service, and Oleg Osheka, Assistant to ZNPP Director General, to an unknown destination. Nothing is currently known about their location or condition.
The Parliamentary Assembly of the Council of Europe (PACE) adopted a resolution declaring russia a terrorist regime. According to the PACE resolution, the leadership of the russian federation has increased threats of nuclear warfare, “continuing its illegal occupation and militarization of the Zaporizhzhia nuclear power plant”, and such threats are abhorrent and reckless, in breach of international law and incompatible with the responsibilities of a nuclear power holding a permanent seat in the United Nations Security Council. In this regard, “the Assembly should look into the issue of the seat of russian federation in the United Nations Security Council”.
Ukrainian specialists restored the 750 kV high-voltage ZNPP–Dniprovsk line.
Energoatom prepared and sent another batch of diesel fuel to the ZNPP. However, as of 10:00 am, the russian side did not allow Energoatom’s vehicle convoy to pass.
At 08:59, the Dniprovsk substation in the Dnipropetrovsk region was damaged by rockets fired by russian troops. This caused emergency disconnection of the 750 ZNPP–Dniprovsk line. The Zaporizhzhia NPP thus underwent total blackout. The diesel generators turned on automatically.
russian terrorists kidnapped Valery Martyniuk, ZNPP Deputy Director General, and are holding him in an unknown place, probably using their methods of torture and intimidation.
Ukrainian specialists repaired and put into operation the 750 kV high-voltage ZNPP–Dniprovsk line that was damaged on 8 October at 00:59 by shelling by russian troops. The radiological background on the ZNPP site and the surrounding area did not change and was within limits.
At 00:59, another shelling attack by russian troops damaged and disconnected the last 750 kV ZNPP–Dniprovsk line. This caused loss of power to the Zaporizhzhya NPP and the diesel generators turned on automatically. The available diesel fuel supplies would allow their performance for 10 days.
russian rosatom corporation created a joint-stock company “Operating Organization of the Zaporizhzhya NPP” with registration in Moscow, with the purpose of managing the occupied ZNPP.
Petro Kotin, Energoatom President, assumed duties of the Zaporizhzhia NPP Director General.
Zaporizhzhia NPP Director General Igor Murashov, who was kidnapped by russian soldiers on 30 September 2022 on the way from the plant to Energodar, was released and was at the off-site ZNPP Emergency Center in Zaporizhzhia.
On the territory of russia, the movement of a freight train with special-purpose military equipment, such as infantry fighting vehicles, self-propelled guns and trucks being in service with the 12th main department of the russian ministry of defense responsible for nuclear engineering support and safety, was detected.
Around 4:00 pm, Zaporizhzhya NPP Director General Igor Murashov was detained by a russian patrol on the way from the plant to Energodar. He was forcibly detained and blindfolded and taken to an unknown destination. There is currently no information about Igor Murashov’s location or fate.
At 01:13, russians shelled the Zaporizhzhya NPP. This caused damage to the equipment connecting ZNPP Unit 6 to the outdoor switchgear. The block transformer and inhouse unit transformers disconnected. The loss of power caused emergency actuation of two diesel generators of safety systems to support operation of the fuel cooldown pumps. At 02:00 am, ZNPP staff found the possibility to set up power supply for Unit 6 inhouse loads from the bus system of other plant units. The diesel generators of Unit 6 were turned off and put into standby.
At 00:20, russians fired missiles at the industrial area of the Pivdennoukraisnk NPP. A powerful explosion occurred 300 m from the PNPP reactors. Inspection established the crash area and found a hole from the missile explosion with a diameter of 4 m and a depth of 2 m and missile fragments. The shock wave damaged the plant buildings and more than 100 windows. Moreover, one of the hydraulic units of the Oleksandriv hydroelectric plant, being part of the Pivdennoukrainsk energy system, turned off.
Three high-voltage power lines also disconnected and then automatically connected to the grid.
The IAEA Board of Governors, including representatives of 35 UN member states, adopted a resolution demanding russia to cease all actions against the Zaporizhzhia nuclear power plant and any other nuclear facility in Ukraine. The document was proposed by Canada and Poland on behalf of Ukraine, which does not sit on the board of the IAEA’s highest decision-making body. 26 countries voted in favor of the resolution, two countries, China and russia, voted against and seven more countries (Egypt, South Africa, Senegal, Burundi, Vietnam, India and Pakistan) abstained.
At night, at 03:41, ZNPP unit 6 was disconnected from the power grid. Preparation for its cooldown and transfer to a cold state are underway. For the past three days, unit 6 has been operating in an island mode, powering its ZNPP needs only at a critically low power level (from 114 to 140 MW), since all communication lines of the Zaporizhzhya NPP with the Ukrainian power system were damaged due to russian shelling.
The russian military once again shelled the city of Voznesensk, Mykolaiv region, which is 30 km from the Pivdennoukrainska NPP. According to preliminary information, the missile hit civilian facilities, and there are casualties.
In a comment to russian propagandists, state traitor Evheny Balytsky threatened to fire at the Khmelnytskyi and Rivne NPPs: “A pair of “Kalibrs” will hit the Rivne and Khmelnytsky NPPs. That’s when these “lightly gendered” people will immediately have a desire to think about their lives. “When we hit the Rivne or Khmelnytskyi nuclear power plants, the rhetoric of the Americans will immediately change”, said the terrorist Balytskyi.
The IAEA published a Report on the results of the mission to the Zaporizhzhya NPP. IAEA inspectors noted that the russian federation has placed military personnel, vehicles and equipment on the territory of the ZNPP, in particular in the turbine halls of power units 1 and 2. In addition, it has been confirmed that there are representatives of “rosatom” at the ZNPP, who have a negative impact on the plant’s personnel, who work under stressful conditions. The mission recorded the damage suffered by the ZNPP during the shelling, in particular: physical integrity was violated, safety systems were not functioning, difficult conditions for personnel, damage to third-party power sources, complications of supply chains, problems with the operability of planned radiation monitoring and emergency measures at the site. In addition, the IAEA is ready to immediately start consultations on the urgent creation of a nuclear protection and security zone at the ZNPP.
Four of the six IAEA representatives of the inspection team completed their activities at the Zaporizhzhya NPP and left the plant site.
During the last three days, the russian occupying forces have continued intensive shelling of the territory around the Zaporizhzhya NPP. As a result, the 750 kV ZNPP – Dniprovska, 330 kV ZNPP – Kakhovska and 330 kV ZNPP – Melitopol transmission lines were damaged and disconnected. The AT 750/330 kV of the ZNPP was also damaged. Other lines of the ZNPP/TPP complex were damaged even earlier.
The 330-kV transmission line ZNPP-Ferosplavna was disconnected due to a fire caused by shelling. Therefore, unit 6, which powered the ZNPP’s own needs, was unloaded and disconnected from the grid.
In the evening, after the russian occupiers shelled the communication lines of the Zaporizhzhya NPP with the energy system of Ukraine and due to insufficient capacity of the last, reserve, line for two power units, at 7:35 p.m. ZNPP unit 5 was disconnected from the power grid. Currently, unit 6 remains in operation, which with limited capacity supplies electricity to the power system of Ukraine through the back-up line, and also powers the Zaporizhzhya NPP’s own needs.
Zaporizhzhya NPP power unit 5, which was disconnected on the morning of September 1 as a result of another mortar shelling by the russian occupying forces at the ZNPP site, was connected to the power grid at 1:10 p.m. Currently, two power units are operating at the plant, which generate electricity for the Ukrainian needs.
At 4:57 a.m., a mortar shelling of the Enerhodar satellite city and the site of the Zaporizhzhya NPP has been committed. As a result, the emergency protection was triggered and operating unit 5 was disconnected. In addition, the ZNPP 330 kV power supply line for its own needs was damaged. In the transitional mode, the power blackout of unit 2 occurred with the start-up of diesel generators. This is the second time in the last 10 days that the criminal actions of the occupiers have led to the unit shutdown and the plant blackout. Unit 6 continues operating in the energy system of Ukraine and at the same time to power the ZNPP’s own needs.
The russians are shelling the pre-agreed route of the IAEA mission from Zaporizhzhya to the ZNPP. Despite reports of intense shelling, the IAEA mission left Zaporizhzhya for Enerhodar. At 14:26, the IAEA mission arrived at the Zaporizhzhya NPP.
As of 18:00, the IAEA Director General Rafael Mariano Grossi and most members of the delegation left the Zaporizhzhya NPP. Currently, there are 5 representatives of the IAEA mission left at the plant, who are unloading the equipment they brought and will continue working at the ZNPP. It is expected that they would stay at the Zaporizhzhya NPP until September 3.
During the day, the russian military continued shelling Enerhodar and the Zaporizhzhya NPP site. As a result, 10 peaceful residents of Enerhodar received injuries of varying degrees of severity, four of them were NPP employees.
At 2:04 p.m., one of the ZNPP power units that was shutdown yesterday, was connected to the grid again. The second of the ZNPP power units, which was shutdown yesterday was connected to the power grid at 9:15 p.m. There are no remarks on the operation of equipment and safety systems.
The EU received a request from the government of Ukraine for potassium iodide pills as part of preventive safety measures to increase the protection of the public residing near the Zaporizhzhya NPP. In return, the European Union will provide 5.5 million potassium iodide pills to protect Ukrainians from possible radiation exposure. In particular, 5 million will be transferred from the strategic reserves of the European Union, another 500 thousand will be provided by Austria.
As a result of hostilities in the area where the Zaporizhzhya NPP is located and fires at the Zaporizhzhya TPP ash dumps, the Dniprovska PL-750 kV overhead line was disconnected twice. Three other communication lines were damaged earlier by russian shelling. As a result, ZNPP unit 5 was disconnected from the grid with the subsequent activation of the emergency protection, unit 6 was transferred to power its own needs.
At 12:29 p.m., after restoring operability of the overhead line PL-750 kV “Dniprovska”, Zaporizhzhya NPP unit 6 was connected to the grid, but already at 2:14 p.m., the overhead line PL-750 kV “Dniprovska” was disconnected again, as a result of which unit 6 was disconnected again from the grid with the subsequent tripping of the emergency protection.
Thus, the actions of the invaders caused the ZNPP to be completely disconnected from the power grid for the first time in the plant’s history. The NPP’s own needs for power supply are currently provided from the energy system of Ukraine through the communication line of the ZNPP – Zaporizhzhya TPP. There are currently no remarks on operation of automation and safety systems. Start-up operations are underway to connect one of the power units to the grid.
To raise clouds of radioactive dust, the occupiers are shelling the ash dumps of the Zaporizhzhya TPP, the place where ash is stored, which is generated during the operation of thermal power plants. This waste has a high concentration of toxic substances and a radiation level that is at least 2.5 times higher than the natural background. When drying, they form dust that can move over considerable distances. As a result of mortar strikes on ash pits, clouds of dust are formed, which are blown by the wind in the vicinity of Enerhodar. Monitoring of the radiation background, which is carried out near the NPP, indicates an increase in the radiation level.
The russian occupiers additionally brought two armored personnel carriers and six special trucks to the Zaporizhzhya NPP repair zone. In total, there are more than 40 units of military equipment on the plant territory, in particular, 16 military vehicles are located near unit 1, and 7 close to unit 1. Another 12 units of equipment are located under the overpass.
At 2:33 p.m., the occupying forces of the russian federation shelled the Zaporizhzhya TPP, as a result of which RTSN-5;6 (reserve transformers of own needs) were damaged and the communication line between the Zaporizhzhya NPP and the Zaporizhzhya TPP (VL-330) was disconnected. At 6:33 p.m., the Zaporizhzhya NPP – Zaporizhzhya TPP line (VL-330) was restored.
Russian occupiers committed the missile strike at the city of Voznesensk, located near the Pivdennoukrainska nuclear power plant, where the missile debris were discovered. The very fact of the shelling of the observation area of the Pivdennoukrainska NPP is another cynical act of russian nuclear terrorism.
The russian occupiers once again shelled the Zaporizhzhya NPP, as a result of which one of the transitional galleries, through which the personnel go from the special buildings to the power units (overpass), was damaged, and the windows in the building were broken.
On August 19-20, 2022, an inspection by the International Atomic Energy Agency took place at the Rivne NPP in the framework of the Agreement between Ukraine and the IAEA on the application of safeguards in connection with the Treaty on the Non-Proliferation of Nuclear Weapons. Purpose of the inspection was to verify the absence of undeclared nuclear material.
At 00:15, the russian occupiers fired in the direction of the training center of the Zaporizhzhya nuclear power plant. It was registered that the shelling was carried out from two place: the bus station and the discharge channel: in the first case it took 1.5 seconds for a strike, and in the second, the strike sound was heard three seconds later.
The SNRIU introduced changes to the operating licenses of power units 1 and 2 of Zaporizhzhya NPP. The corresponding Order No. 501 of August 18, 2022 was signed by Oleh Korikov, the Acting SNRIU Chairman – Chief State Inspector for Nuclear and Radiation Safety of Ukraine. According to the Order, operation of unit 1 of the Zaporizhzhya NPP is carried out by the operating organization in the states of “fuel reloading” – “cold shutdown”. The Order also specifies that the operation of the Zaporizhzhya NPP unit 2 is carried out in a “cold shutdown” state. The basis for introducing changes was the application of the NNEGC “Energoatom” and the documents submitted with it, as well as the Resolution of the SNRIU Board of August 4, 2022 “On the Current Safety State of the Zaporizhzhya NPP power units under the Conditions of Occupation by the russian federation Military”.
From 3:00 p.m. to 3:30 p.m., the russian occupiers shelled the city of Enerhodar more than 6 times, as a result of which an employee of the Zaporizhzhya NPP died.
The IAEA has published a note verbale dated August 12, 2022 of the Delegation of the European Union to international organizations in Vienna and a Joint Statement on behalf of the IAEA member countries regarding the situation at the Zaporizhzhya nuclear power plant. The IAEA member countries call on the russian federation to immediately withdraw its military forces and all other unauthorized personnel from the Zaporizhzhya nuclear power plant, its immediate surroundings and all of Ukraine, so that the operator and the Ukrainian authorities can resume their sovereign responsibilities in the framework of Ukraine’s international policy, recognized borders and legitimate operational personnel of the ZNPP could perform their duties without outside interference, threats or unacceptably difficult working conditions.
Five “strikes” were registered in the area of the ZNPP command post, next to the welding area and the radiation sources storage facility.
For the third time today, the russian military shelled the area of the Zaporizhzhya nuclear power plant, namely the fire unit, located outside the ZNPP territory and designed to protect it from fires and extinguish them in case of emergency situations at the plant. As a result of the plant shelling, it was not possible to rotate the personnel in time, because for the safety of the employees, the buses with the next shift personnel were turned back to Enerhodar. Until the situation finally stabilizes, the employees of the previous shift will continue working.
The SNRIU Licensing Commission has resumed the validity of the licenses of the Chornobyl Nuclear Power Plant for the right to carry out activities related to the decommissioning of Chornobyl NPP units 1, 2 and 3, operation of the confinement complex and the Shelter, processing and storage of radioactive waste (RW), as well as the validity of the licenses of the Central Enterprise for the Radioactive Waste Management to conduct activities at the stages of the construction and operation of radioactive waste disposal facilities at the Vektor production complex, for operation of radioactive waste storage facilities of Chornobyl origin in the Exclusion Zone territory, as well as RAW processing and storage.
As of 08:00, the Zaporizhzhya NPP is operating with the risk of violating radiation and fire safety standards.
The russian invaders probably mined the Zaporizhzhya NPP. This opinion was expressed by The Insider publication, which states that the russian military mined the turbine hall of one of the ZNPP power units. According to another information source, the territory around the ZNPP was mined. In addition, multiple rocket launch system batteries are deployed near the village of Vodyane, the closest one to the ZNPP. Moreover, russian soldiers store mines and ammunition in the immediate vicinity of power units, under overpasses, and part of the ammunition is stored inside the power unit.
In the evening, the russian occupiers once again fired missiles at the Zaporizhzhya nuclear power plant site and the city of Enerhodar. They hit the ZNPP site directly next to the plant’s dry spent nuclear fuel storage facility. Apparently, they aimed specifically at the SNF containers, which are stored in the open air near the places of shelling. 174 containers, each of which contains 24 spent nuclear fuel assemblies! Three radiation monitoring sensors around the ZNPP site were damaged due to enemy missile attacks. Therefore, timely detection and response in case of deterioration of the radiation situation or leakage of radiation from spent nuclear fuel containers is currently impossible. About 800 square meters of windows surface were damaged due to numerous small fragments from the explosions in various NPP buildings. As a result of the explosions, one ZNPP employee received a shrapnel wound, and was taken to the city hospital. All russian military personnel, constituting up to 500 persons are deployed at the ZNPP site since the day of its seizure, as well as personnel of the terrorist rosatom, hid are hiding in the bunkers of the plant’s crisis center and technical support center.
As a result of shelling by the russian occupiers, at 2:30 p.m., three “strikes” were registered near the ZNPP industrial site. The enemy hit the 330 kV high-voltage communication line of the ZNPP – Zaporizhzhya TPP autotransformer. As a result, it was damaged, emergency protection was actuated at one of the power units, diesel generators were switched on. Currently, this unit is unloaded and disconnected from the power grid.
Military terrorists from the russian federation fired Enerhodar with multiple rocket launch systems and are creating a humanitarian disaster in the Zaporizhzhia NPP satellite city. The invaders bombed the “Luch” power station, as a result of which almost the entire city (6 out of 7 microdistricts) was left without electricity. The water intake station is also out of operation, there is no water in the city.
In the evening, russian terrorists shelled the Zaporizhzhya NPP for the second time with multiple rocket launch systems. Three “hits” were recorded right on the NPP site, near one of the power units where the nuclear reactor is located. The russian terrorists damaged the nitrogen-oxygen station and the joint auxiliary building. There are risks of hydrogen leakage and release of radioactive substances. The fire hazard is high.
Condemning russia’s unjustified invasion of Ukraine, including russian aggression at or near nuclear facilities, Canada has allocated $1 million to the IAEA to strengthen safety and protection at Ukrainian nuclear facilities and $5 million to the U.S. Department of State to support Ukraine in detecting and responding to illegal nuclear transportations on its territory”.
At least 14 units of heavy military equipment with ammunition, weapons, and explosives were placed by the russian military in the ZNPP-1 turbine hall close to the equipment that ensures the operation of the turbogenerator, namely near the main oil tank, which contains flammable oil that cools the steam turbine. There is also explosive hydrogen, which is used to cool the generator. The military equipment of the invaders made it impossible to access the unit 1 turbine hall for specialized fire-fighting vehicles, which increases the risk of a fire.
At the ZNPP, the russian occupiers kidnapped Serhii Pykhtin, the Deputy Head of the decontamination shop for operation and radioactive waste management, and Elena Ryabtseva, the decontamination shop engineer. In addition, they forcibly took the ID passes and entered the radiation zone of the ZNPP -2, thereby violating the established norms of staying in this zone and exposing the personnel to the risk of radiation contamination. Additionally, the sane day, the russian occupiers “appropriated” the ZNPP educational and training center and, threatening the NPP personnel with weapons, seized the cafeteria.
The russian occupiers continue to kidnaping nuclear power plant personnel at the temporarily occupied ZNPP. In particular, Ihor Kvashnin, the Head of the ZNPP Environmental Protection Service, was kidnapped.

Despite this, there is no new damage of the pumping room, cooling towers, isotope laboratory of the neutron source, as well as systems and components that affect safety.
The russian invaders looted and destroyed the Central Analytical Laboratory in Chornobyl, in which highly active samples and samples of radionuclides were located. At the same time, an unauthorized entry into the storage facility for radiation sources took place, in which reference radioactive solutions and calibration sources were stored. The occupiers stole and damaged 133 sources with a total activity of about 7 million becquerels. The location of the stolen sources is unknown. The degree of integrity and safety of the calibration sources and reference radioactive solutions cannot be determined, and the condition of the damaged ones will be clarified after a relevant inventory and measurements.
Rosatom representatives have been illegally present at the ZNPP site for a long time. Due to the presence of russian occupation forces and a large number of military equipment at the ZNPP site and in satellite city Enerhodar, personnel and their families are under continuous psychological pressure. This can lead to errors in personnel work, which affect NPP safety and lead to emergencies or accidents at NPPs.
At ChNPP, which is under the occupation of the russian federation, a partial rotation of personnel took place. 50 employees were replaced by 46 NPP employees who volunteered to perform their official duties for proper operation of the Chornobyl facilities.
Since hostilities are continued in the Piatykhatky region in Kharkiv, there is still no power supply of the neutron source.
For 23 days in a row without rotation, the ChNPP personnel courageously and heroically perform their functions to ensure the safe operation of these facilities. It is impossible to replace personnel in combat conditions, although rotation scenarios are being actively developed.
Hostilities in the Piatykhatky region in Kharkiv led to damage of power supply lines, due to which the power supply of the neutron source was stopped.
Due to the hostilities in the region and capture of the ZNPP site and nearby territories by the russian occupation forces, there is a potential threat of ZNPP de-energization. The Zaporizhzhya, South Donbass and Kakhovka 750 kV high-voltage lines were damaged, which led to the disconnection of the ZNPP autotransformer communication line (750/330 kV) with the Zaporizhzhya TPP from 14:00 to 20:00. After repair of the detected damage, the line was restored.
Power supply of all facilities was restored at the ChNPP site, all diesel generators that provided emergency power supply for these facilities were disconnected at 17.45. The information on ChNPP power supply from the Belarusian Mozyr 330 kV substation was disproved by the Energoatom.
Two 750 kV high-voltage lines (Zaporizhzhya and South Donbass) are still not connected, the Kakhovka high-voltage line was disconnected at 14:29.
Until now, two 750 kV high-voltage lines (Zaporizhzhya and South Donbass) remain disconnected.
For twenty days there is no rotation of the ChNPP personnel, who courageously and heroically continue to perform their functions to ensure the safe operation of the ChNPP facilities. It is impossible to replace personnel in combat conditions, although rotation scenarios are being actively developed.
The line energizing ChNPP and Slavutych was again damaged by occupiers after its repair by the Ukrenergo repair team.
Russian occupation troops in close proximity to the ZNPP units detonated unexploded ordnances during the shelling of the industrial site on 4 March 2022.
The Ukrenergo repair team repaired the high-voltage power line energizing ChNPP and Slavutych. At 19:07, the line was energized and restoration of the power supply for ChNPP and Slavutych infrastructure has started. However, it was not possible to complete these activities, because occupiers soon damaged the line again. The Ukrenergo repair team is forced to go again to the occupied territory near ChNPP to look for and eliminate new damage.
According to ZNPP, there is a continuous rotation of operating and daytime personnel who monitor the state of power units and ensure their safe operation in accordance with the requirements of operational documents. The NPP automated radiation monitoring system and automated radiation monitoring system in the control area and observation area are operated in regular mode, no changes in the radiation situation at the NPP site, in the observation area and in the control area have been recorded.
11 representatives of the russian state atomic energy corporation rosatom arrived at the Zaporizhzhya NPP. These persons do not interfere in the operation of nuclear facilities yet, NPP management and operation is carried out exclusively by the ZNPP personnel, however, all technical solutions should be coordinated with the invaders. Ukraine did not make any request for advisory, technical or other assistance from the russian federation. The presence of these persons on the territory of ZNPP is illegal and is in no way related to nuclear and radiation safety.
Two 750 kV high-voltage lines (Zaporizhzhya and South Donbass) have not yet been connected; measures are being taken to restore the damaged high-voltage lines. This issue is complicated by active hostilities in the places where the lines are damaged.
Once again, the neutron source in Kharkiv was bombed, due to which it was completely de-energized and there was surface damage of the building. The power supply of systems/components important to safety has been restored. Damage that could affect the state of nuclear and radiation safety was not identified.
As a result of the damage of the 750 kV ChNPP – Kyiv high-voltage line caused by invaders’ shelling, ChNPP and all nuclear facilities of the exclusion zone were de-energized. Due to the lack of power supply, there is no cooling of the spent fuel assemblies located in the spent fuel storage facility. As a result, the temperature in the spent fuel pools will increase, which causes steam generation and release of radioactive substances into the environment. Moreover, due to the de-energization, the fire extinguishing system will not work, as well as ventilation, and the NPP personnel can receive a dangerous radiation dose. Power supply restoration is impossible due to hostilities.
For the thirteenth day, there has been no rotation of the ChNPP personnel, who courageously and heroically continue to perform their functions to ensure the safe operation of the ChNPP facilities. Regulatory control of the state of nuclear and radiation safety at the ChNPP site and on the territory of the exclusion zone is not possible yet.
The Council of the Organization for Economic Cooperation and Development (OECD) suspended the participation of russia and Belarus in OECD bodies.
ZNPP-6 was shut down for emergency maintenance. As a result of ZNPP site shelling on 4 March and after a detailed inspection, it was detected that the oil system of the unit transformer was damaged.
Nuclear research facility “Neutron Source” located at the site of the National Science Center “Kharkiv Institute of Physics and Technology” was bombed. Due to this, the RU-0.4 kV substation was destroyed, cooling system air conditioner cables of the klister gallery of the linear electron accelerator were damaged; the heating line to the system of buildings and structures of the neutron source was damaged, windows were broken in the building of the pump room and cooling towers, in the isotope laboratory. In some places, there was surface damage of the main facility building.
Several sensors for monitoring the neutron flux, gamma radiation dose rate and air radiation contamination failed in the Chornobyl zone at the Shelter. Due to this, further monitoring of criticality and a number of radiation parameters in one of facility rooms is impossible. Due to the lack of a sufficient number of maintenance personnel and special equipment as a result of the occupation, the restoration of damaged equipment of systems important to nuclear and radiation safety is not carried out.
On this day, the occupiers also staged the provision of humanitarian assistance, in particular food and cigarettes. This action was aimed at forming informational occasions for the media and was not related to the assistance of the ChNPP personnel, which have been held hostage by the russian military for almost two weeks. After the categorical and public refusal of the enterprise personnel from the “help” of the occupiers, the enemy used tricks: the military put on the NOVARKA uniform, which was available in changing rooms and they accepted the assistance with joy and gratitude. This was filmed by the russian media.
At 16:06, the 750 kV high-voltage line was disconnected due to its damage as a result of shelling in the area of the Vasylivka village, Zaporizhzhya region.
ZNPP operating personnel is constantly under the pressure of the armed occupiers, although, despite this, they continue to monitor the state of the power units and provide their operation.
The Zaporizhzhya NPP was captured. As a result of artillery shelling of the ZNPP industrial site, ZNPP-1 reactor building was damaged, two artillery shells hit the area where the Dry Spent Fuel Storage Facility Site was located. As a result of a fire caused by enemy shelling of the ZNPP industrial site, the building of the training center, which is located close to the ZNPP industrial site, was damaged.
The Polish Nuclear Society has issued a statement on the termination of cooperation and any official contacts with russian organizations until the end of hostilities and bringing to justice all those responsible for violating international law.
There has been no rotation of the operating personnel at the Chornobyl NPP for 7 days. It is impossible to replace personnel in combat conditions, although rotation scenarios are being actively developed. Control over the state of nuclear and radiation safety of nuclear installations and other facilities at the ChNPP industrial site and on the territory of the exclusion zone has been lost.
30 km from the South Ukraine NPP, fighting continues near Voznesensk: rashist vehicles drive into the city, Voznesensk is shelled by Grad missiles. According to adviser to the Minister of Internal Affairs Anton Gerashchenko, a group of more than 20 helicopters of occupiers with paratroopers flew from the Mykolaiiv region towards Voznesensk, where the South Ukraine NPP is located. However, the Ukrainian military stopped the invaders’ offensive, and two bridges were blown up to prevent approaching of the russian military to SUNPP.
As a result of rocket attacks, the communication network of the Zaporizhzhya NPP was damaged. After that, the automated radiation monitoring system (ARMS) of the Zaporizhzhya NPP fully lost its operability and failed to transmit data to the International Radiation Monitoring Information System (IRMIS). ARMS repair and resumption of its work is complicated by military operations near the Zaporizhzhya NPP.
At night, at 01:20, near the Kyiv Radon radioactive waste disposal site, a shell hit the fence. According to the Radon Corporation, as a result of the explosion, the radioactive waste disposal facilities remained undamaged. Any activities related to radioactive waste management, including transport of radioactive materials, were terminated. The radiation background is within 0.09-0.15 µSv/h, there is no surface contamination.
On the fourth day of the war against Ukraine, Putin made a statement about the transfer of the deterrent forces of the Russian army to a special mode of combat duty and ordered to put Russia’s nuclear forces on high alert. With this statement, the President of the Russian Federation considered possible to use nuclear weapons on the territory of Ukraine.
Today, four operating nuclear power plants in Ukraine are operated in regular mode and are under special control, since there are risks of their capture. Near Energodar, which is a satellite city of the Zaporizhzhya NPP, active battles continue, eyewitnesses report on numerous military equipment. Cruise and ballistic missiles were randomly fired from the territory of Belarus at Ukrainian cities, that is why the power units of the Rivne and Khmelnitsky nuclear power plants are under threat.
On this day, in order to spread fake news about the shelling of invaders in Chornobyl by the Armed Forces of Ukraine, enemy Russian troops simulated an air battle over the exclusion zone. This was reported by the State Agency of Ukraine on Exclusion Zone Management. However, it should be noted that the Ukrainian military troops are aware of the consequences and do not conduct military operations near the Chornobyl zone.
Online, the Automated Radiation Monitoring System (ARMS) recorded an increase in the radiation background of the Chornobyl exclusion zone, which was associated with disturbance of the topsoil due to the movement of heavy equipment and rise of contaminated radioactive dust into the air.
The radiation state at operating nuclear power plants and adjacent territories has not changed and is within standard values. As for the situation on the territory of the exclusion zone and zones of unconditional (mandatory) resettlement, to this day there is no access to the automated radiation monitoring system. The latest recorded data indicate that the average values of the equivalent dose rate in the area of radioactive waste storage facilities (Vektor, Pidlisnyi, Stage 3 and Buryakivka) are up to 15 times higher.
At 20:00, Prime Minister of Ukraine Denys Shmyhal informed that all facilities of the Chornobyl nuclear power plant have been taken under the control of Russian armed groups. ChNPP workers are held hostage.
