Cavitation Treatment is a Special Technology for Protecting the Reactor Pressure Vessel

Framatome has been awarded a contract to implement a special technology to protect the reactor pressure vessel at four U.S. nuclear power plants. The cavitation treatment process extends the life of the reactor pressure vessel, protecting it from corrosion. Cavitation treatment is a solution to reduce surface contamination, which can prevent corrosion cracks without damaging […]

Researchers Developed a New Method of Enriching Uranium in Seawater

Researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) have developed an innovative method of pre-enriching uranium in seawater by membrane filtration based on considerable differences in the diameter of hydrated ions between UO22 + and the main coexisting ions. Researchers fabricated a new type of glycine cross-linked composite graphene oxide […]

The Artificial Neuron Powered by a Tritium Radiovoltaic Micro-Power Generator

A joint team from Arkenlight (Great Britain) and Axorus (France) have built the first artificial neuron powered by a Tritium Radiovoltaic micro-power generator. This electronic piece of technology is a circuit behaving like a biological neuron. It is used inside an artificial retina for patients suffering from Age-related Macular Degeneration (AMD) and will also be […]

First Technical Analysis of the Integral Molten Salt Reactor Completed

On 7 June 2022, the Canadian Nuclear Safety Commission (CNSC) and the U.S. Nuclear Regulatory Commission (NRC) completed the first joint technical analysis of the Terrestrial Energy Integral Molten Salt Reactor (IMSR). The technical inspection of the integral molten salt reactor was performed in the framework of the cross-border regulation program established in August 2019 […]

Experts of the State Scientific and Technical Center for Nuclear and Radiation Safety are going to conduct a radiological survey of the Kyiv region territories

In June, experts of the State Enterprise «State Scientific and Technical Center for Nuclear and Radiation Safety», upon request of the State Nuclear Regulatory Inspectorate of Ukraine (SNRIU), are going to conduct a radiological survey of the Kyiv region territories that were temporarily occupied by the russian troops. Since the russian military equipment invaded Ukraine […]

Ivano-Frankivsk Developed a Device for Monitoring and Notification on Chemical and Radiation Threats

Ivano-Frankivsk team EcoCity will complete the development and production of the first prototype of the Hazard Detector soon, designed to monitor releases of chemicals (chlorine, phosphine) and measure the radiation background. Hazard detector can be equipped with 2 electrochemical, thermocompensated sensors for harmful gases from the list of CL2, NH3, PH3, H2S, HCL, HF, NO2, […]

Jacobs Developed a Tool to Study the Debris of a Damaged Reactor at the Fukushima NPP

Jacobs has designed and built a robotic tool to obtain crucial information about the state of a damaged nuclear power reactor at Fukushima Daiichi in Japan. The remotely operated device will collect pebble-like debris that was deposited at the bottom of the reactor containment vessel after the meltdown caused by the earthquake and tsunami. The exact […]

Radiation Background Monitoring Sensors Installed in Kyiv

In Kyiv, atmospheric air monitoring points were supplemented by an automated radiation background monitoring system. Five sensors, based on reference the air state monitoring points, record the background radiation level in real-time mode. The measurement range is from 0.04 μSv/h to 30 Sv/h (the reference level for Kyiv is 0.26 μSv/h). Anyone can monitor the […]

Public Call of Acting Head of the State Nuclear Regulatory Inspectorate of Ukraine to the International Atomic Energy Agency (IAEA)

At night on March 4, 2022, the first in the world history forcible seizure of Zaporizhzhia NPP took place, as a result of shelling of which the armed forces of the russian federation killed three Ukrainian defenders and created unprecedented threats to the nuclear safety of the plant, which could lead to a catastrophe on […]

Seismic and Acoustic Data to Monitor Operational States of Nuclear Reactors 

Researchers of the Oak Ridge National Laboratory (ORNL) explored the possibility of using seismic and acoustic data recorded 50 meters away from a nuclear research reactor to predict whether the reactor was on or off with 98% accuracy.   Using ORNL’s high flux isotope reactor, the researchers placed remote sensors near the facility and continuously recorded […]
