Spent Fuel Management

By the end of 2000, the six Slovak VVER-440 units used 7 300 spent fuel assemblies. From this amount, approximately 700 assemblies were exported to the Russian Federation, 1 200 were cooled down in pools adjacent to the reactors, and 5 400 pieces were stored in a wet interim spent fuel storage facility at the Bohunice site. This facility was extensively refurbished during 1997-2000. The refurbishment resulted also in a capacity increase from 5 000 up to 14 000 fuel assemblies (or 1 680 tU). This capacity is sufficient for the fuel storage needs of both Bohunice till its expected closure and of Mochovce till 2015. By that time, it will be necessary to build a new storage facility at the Mochovce site. According to current intentions, the facility will probably be based on the dry storage technology.

The fundamental conception for the back end fuel cycle management remains unchanged. It is still expected that spent fuel will be ultimately disposed in a deep underground geological repository. Activities on the selection of an adequate site are thus continuing.

Radioactive Waste Management

The whole amount of radioactive waste from the past operation of the Bohunice units is stored temporarily on the site. The concepts of radwaste management from nuclear power installations and other organizations using sources of ionization radiation were prepared in 1993. The following production process fixing facilities have been constructed or are being built

· A bitumenization facility for fixing concentrates was commissioned in 1995;

· vitrification facility is in the stage of active comprehensive testing;

· radwaste-processing center consists of a cementation facility with a possibility to densify concentrates, of a high-pressure pressing and of an incineration installation.

low- and medium-level radwaste from Bohunice will be stored in fiber-concrete containers. To make the system of radwaste management complete, it was necessary to commission the operation of a disposal facility for low- and medium-level radwaste at the Mochovce site in 2000.

*) Volume "as dispo" is an estimate of the final disposal gross volume of waste currently in interim storage. Note that if volume "as dispo" is not provided, it's assumed to be the same "as is".
