The fuel of Paks Nuclear Power Plant is uranium dioxide, of which some 42 tonnes are loaded in each reactor. After their use, the fuel assemblies are removed from the reactor and loaded into the decay pool at the reactor, where they are stored for a period of minimum 3 years. 110 spent fuel assemblies per unit are generated every year.

After the expiry of the decay period, the fuel assemblies are placed in a water filled transfer cask. Following the decontamination of the outer surface, the cask is transferred on a railway wagon, to the ISFS. The transfer cask is capable of accommodating 30 fuel assemblies. In the ISFS facility, the fuel assemblies are each lifted into the fuel drying equipment, and then loaded into the vertical storage tubes.

At the end of 2008, 5587 fuel assemblies were stored in the Interim Spent Fuel Store.

Please look around in the charge hall of the ISFS!
