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

21 April

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.

13 April

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.

11 April

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.

8 April

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.

6 April

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.

29 March

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.

25 March

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.

20 March

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”.

17 March

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.

13 March

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.

9 March

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.

6 March

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?”

3 March

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.

2 March

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.

28 February

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.

27 February

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.

25 February

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.

23 February

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”.

20 February

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.

19 February

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.

18 February

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.

14 February

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.

10 February

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.

6 February

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.

3 February

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.

2 February

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.”

26 January

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.

25 January

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.

20 January

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.

18 January

An IAEA permanent monitoring mission launched its work at the Chornobyl NPP.

17 January

An IAEA permanent monitoring mission launched its work at the Rivne NPP.

16 January

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.

14 January

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.

11 January

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.

7 January

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.

6 January

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.

5 January

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.

3 January

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.

2 January

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.

29 December

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.

19 December

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.

14 December

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.

13 December

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.

10 December

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.

9 December

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.

8 December

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.

7 December

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.

24 November

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.

23 November

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.

20 November

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.

17 November

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.

16 November

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.

15 November

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.

11 November

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.

4 November

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.

3 November

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.

2 November

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.

1 November

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.

30 October

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.

27 October

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.

24 October

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.

23 October

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.

18 October

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.

17 October

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.

13 October

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”.

12 October

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.

10 October

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.

9 October

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.

8 October

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.

5 October

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.

3 October

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.

30 September

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.

21 September

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.

18 March  

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.  

17 March  

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.  

16 March  

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. 

15 March  

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. 

14 March  

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. 

13 March  

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. 

12 March  

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 March  

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. 

10 March  

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. 

9 March  

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. 

8 March  

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.  

7 March  

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.

6 March  

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.  

5 March  

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.  

4 March  

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. 

3 March

2 March  

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. 

1 March  

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. 

27 February

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.

26 February

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.

25 February

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.

24 February

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.
