Cooperation with Korea Continues

In July 2020, ChNPP participated in a joint on-line meeting between the State Agency of Ukraine on Exclusion Zone Management (hereinafter referred to as SAUEZM) and the Korea Atomic Energy Research Institute (hereinafter referred to as KAERI). The meeting was devoted to a project for establishment of a pilot facility to test the technologies of radioactive concrete treatment and metal foam decontamination.

At the end of September, one more step towards this direction was taken, namely Mr. Serhii Kalashnyk, the SAUEZM Head, and Dr. Won Seok Park, the KAERI President, signed a Memorandum about Technical Cooperation in research and development sphere.

“Agency supports continuously and extensively the international cooperation with partner institutions as only having combined the best world technologies and practices we will be able to implement more efficiently all the tasks we face. Namely these are ChNPP decommissioning and Shelter transformation into an environmentally safe system,” emphasized SAUEZM Head Serhii Kalashnyk.

Chornobyl NPP takes part in WANO working meeting

From 29.09.2020 to 01.10.2020, the moscow Center of the World Association of Nuclear Operators (WANO-MC) has organized a working meeting on "NPPs Equipment Aging Management.”

Within three days, about 50 representatives from 10 countries will discuss the problems of aging management (resource management) of structures, systems and elements (SSE) at different stages of Power Units operation, criteria for selection of equipment to be included in the aging management program, identification of the dominant mechanisms of SSE degradation, their obsolescence and other issues.

Taking into account the situation connected with the COVID-19 global pandemic, the event is held in the format of online video conference, all discussions and presentations are arranged remotely.

Operation of the Facility for Materials Release from Regulatory Control

On September 17, Chornobyl NPP agreed with the State Nuclear Regulatory Inspectorate of Ukraine the required documentation to start a pilot operation of the facility for materials release from regulatory control.

The facility is the last stage of the radioactive materials management process. It will allow substantiating the possibility of materials release from regulatory control and returning them to industrial use using the spectrometric measurements. In other words, the facility will confirm that the previously contaminated metal is completely decontaminated and now is safe for reuse outside the Exclusion Zone.

The program of pilot operation stipulates a preliminary procedure for adjustment of all the necessary modes. The capacity of the facility is 10 tons per day, and it will be achieved during pilot operation.

The First ChNPP SFA Prepared for Long-Term Storage

Within the framework of hot tests commenced on September 10, 2020, at the new Interim Spent Fuel Storage Facility of Chornobyl NPP, all the operations related to the first real spent fuel assembly (SFA) preparation for storage have been successfully completed.

These procedures include the transfer basket lifting from the railcar to vertical position, unpacking, then moving an individual SFA to hot cell, cutting and repacking.

So, it can be deemed that all stages starting from the fuel transportation from ISF-1 to ISF-2 and through to its processing for long-term storage were not only tried and tested with dummies but also with an existent SFA.

Currently, similar activities are carried out with the second spent fuel assembly.

Chornobyl NPP Starts Major Stage in Spent Nuclear Fuel Management

On September 10, “hot tests” commenced at the new Interim Spent Fuel Storage Facility No.2 (hereinafter referred to as ISF-2), under the specific permit for commissioning of the nuclear facility issued by the State Nuclear Regulatory Inspectorate of Ukraine.

The day before, the first batch of 9 spent fuel assemblies was loaded into the transfer basket at ISF-1, in the presence of the IAEA inspectors, and this morning the basket was transferred from the wet-type storage facility (ISF-1) to the new facility (ISF-2) for further spent fuel handling.

Spent fuel is transported by a special railcar which also serves as biological shielding to protect personnel from radiation exposure.

ChNPP Acting Director General Volodymyr Pieskov notes that the start of hot testing was preceded by long preparatory work at both ISF-1 and ISF-2. Spent nuclear fuel handling at both storage facilities and its transportation is a comprehensive set of quite serious and interconnected operations, whereas the “hot” tests represent an important procedure which from now on will use the real spent fuel assemblies, not the dummies.
