Fortum Power and Heat Oy, the operator of the Loviisa Nuclear Power Plant, has continued the efforts for acquiring an optional fuel supplier from western sources besides the present Russian fuel supplier. Together with the Hungarian Paks utility, test fuel assemblies have been bought from the BNFL. Five lead assemblies from BNFL (British Nuclear Fuels ) were loaded in Loviisa in 1998 and from 2001 it is planned that half of the fuel is delivered by the BNFL for five years.
Uranium for TVO 1 (Teollisuuden Voima Oy ) and TVO 2 comes (or has come) from Canada, Austria, Niger, China and Russia. Most of the enrichment has taken place in Russia, the rest in Western Europe. Fuel elements delivered to Olkiluoto have been manufactured by ABB Atom (currently Westinghouse Electric Sweden) in Sweden, Siemens in Germany and GENUSA ( Enusa Industrias Avanzadas) in Spain.
Spent fuel from the reactors is stored for a few years in the fuel pools at the reactor buildings. Thereafter, they are transferred to interim spent fuel storage at the power plant sites. Fortum Power and Heat Oy and TVO are responsible for both the acquisition of fuel and the management of spent fuel.
Repositories for medium and low-level wastes are already in use at Olkiluoto and Loviisa sites. A specialised company, Posiva, is taking care of the necessary R&D activities, design and implementation of the spent fuel disposal project in Finland. In the future Posiva also aims to supply similar services for the needs of other countries.
