The State Inspectorate for Nuclear Regulation of Ukraine (SNRCU) said on 24 May that it was about to begin a scheduled inspection the Chernobyl NPP to verify compliance with the requirements for the management of nuclear energy and the performance of organisational and administrative functions related to nuclear and radiation safety. During the inspection, the security status of the Shelter facility will also be checked.

On 21 May, SNRCU Chairman Grigori Plachkov presented the Chernobyl NPP’s Acting Director General, Valery Seydi, with a permit to begin unloading used fuel from wet storage SNF-1 and transporting it to the new dry storage facility, SNF-2. The licence for the right to conduct the work was issued by the SNRCU on 22 April.

Plachkov also handed over a licence for the right to carry out activities for processing liquid radwaste, namely the operation of a plant for processing liquid radioactive waste.

During the operation of the Chernobyl NPP from 1977 to 2000, more than 21,000 fuel assemblies accumulated at the station, which are now stored in the ISF-1 wet used fuel storage facility. ISF-1 was not designed for long-term storage of fuel, and its service life is limited, necessitating removal of the stored assemblies to ISF-2, construction of which was recently completed by Holtec .
