    On June 8, ChNPP started a 10-year period of spent nuclear fuel transportation from the old storage facility to a new one.

    The green light for this process was given by obtaining all necessary permits and licenses for operation of the new Interim Spent Fuel Dry Storage Facility (ISF-2), as well as by the successful hot testing of the facility, during which 186 spent fuel assemblies were transported, processes and placed for storage in test run mode.

    Below there are five key facts you need to know about this process:

    1. The new spent fuel storage facility will accept only fuel from ChNPP.

    On June 7, an enterprise-wide emergency response drill took place on the site of the newly built Interim Spent Fuel Dry Storage Facility No.2 (ISF-2).

    Under the exercise scenario, during transportation-and-process operations some breakage of the crane ropes occurred that caused the falling of a transfer cask filled with spent nuclear fuel. As the consequence of this container fall, the radiation background level within the working area became higher.

    In line with the approved formal procedures, ISF-2 personnel were alerted to the radiation hazard and moved to a safe place.

    According to Dmytro Kondratov, Head of Emergency Preparedness and Response Department, the scenario exercised at this drill is very unlikely, but if such a situation occurs, the power plant staff will be prepared for it.

    On May 21, 2021, with witness of Head of the State Agency of Ukraine on Exclusion Zone Management Serhii Kostiuk, the State Nuclear Regulatory Inspectorate of Ukraine handed over a Licence ОВ 001092 to the State Specialized Enterprise Chornobyl NPP to carry out the activity on radioactive waste (RAW) processing, storage in terms of liquid RAW processing, namely operation of the Liquid Radioactive Waste Treatment Plant (LRTP).

    Owing to this step, Chornobyl NPP can in full process and store the liquid radioactive waste generated at ChNPP during the operation of Power Units and at the decommissioning stage.

    During the awarding of the license, Head of the State Nuclear Regulatory Inspectorate of Ukraine Hryhorii Plachkov highlighted the importance of actions carried out within the ChNPP decommissioning and safe storage of spent nuclear fuel and RAW, and wished the enterprise top management and the Agency the continued success and safe work.

    On May 21, 2021, the SSE Chornobyl NPP Acting Director General Valeriy Seyda was handed over ЕО 000859/1/15 Individual Permit of the SNRIU by a Head of the State Nuclear Regulatory Inspectorate of Ukraine – Chief State Inspector for Nuclear and Radiation Safety Hryhorii Plachkov; the permit is for retrieval of standard spent nuclear fuel from the Interim Spent Fuel Wet Storage Facility (ISF-1).

    This permit obtaining enables the Chornobyl NPP to start the next important stage of ChNPP decommissioning – i.e. activities and operations for removal of spent nuclear fuel from ISF-1 and the spent fuel transportation to ISF-2 for the long-term storage.

    On 19 May, nuclear and radiation safety issues of Object Shelter were discussed during an online meeting of the Parliamentary Committee on Environmental Policy and Nature Management.

    Participants of the discussion, in addition to members of the Committee, included Acting Director General of SSE Chornobyl NPP Valeriy Seyda, Head of the State Agency of Ukraine for Exclusion Zone Management Serhii Kostiuk, Director of the Institute for NPPs Safety Problems Anatolii Nosovskyi, Chairman of the State Nuclear Regulatory Inspectorate of Ukraine Hryhorii Plachkov, and other experts on NPP safety.

    The meeting was primarily focused on the issues regarding probability of self-sustained chain reaction in fuel-containing materials (FCM) of Object Shelter.
