The first container holding damaged nuclear fuel has been placed in the interim spent nuclear fuel storage facility (ISFSF) at Ignalina nuclear power plant (INPP) in Lithuania. Work began in August to remove 367 damaged assemblies stored at the INPP site – the first time such an operation has been carried out at a plant with RBMK reactors. The damaged fuel comprises assemblies that became deformed or acquired cladding defects while in the reactor or during transportation and handling. A total of 182 damaged fuel assemblies are stored at Ignalina unit 1 and 185 at unit 2. The total number of damaged fuel assemblies stored at both units is relatively small, accounting for only 1.7% of all the fuel assemblies stored at the reactors. All damaged fuel will be placed in 22 containers out of 190, which will be transported to the interim used nuclear fuel storage facility.
