In the same year, a contract with American Westinghouse will terminate. Today, the representatives of CEZ, a. s., and Russian TVEL have signed a contract for the supply of nuclear fuel for two VVER-1000 reactors of Temelin Nuclear Power Plant. Namely, the contract was signed by Jiri Borovec, Vice-Chairman of the Board of Directors and Head of Generation Department, and Daniel Benes, Vice-Chairman of the Board of Directors and Head of Administration Department, for CEZ, and Anton Badenkov, TVEL Deputy President, for TVEL. CEZ selected the new supplier of fuel for Temelin in a tender in which also the present supplier, i.e. Westinghouse, participated, besides TVEL. The contract provides for the supplies for both units for the following 10 years, i.e. until 2020. During the term of the contract, TVEL is supposed to supply approx. 400 tons of fuel. The aggregate contract value is several billion Czech crowns. Cooperation with TVEL as a supplier of fuel to Czech nuclear power facilities comes as nothing new. TVEL is a long-time supplier of fuel to another Czech nuclear power plant in Dukovany. In one reactor of Temelin Nuclear Power Plant, there are 163 fuel units in total containing 92 tons of fuel. Annually, approx. 1/4 of fuel, i.e. 40 units (23 tons of fuel), is replaced. Czech nuclear power plants generate nearly 42% of the electric power production in the Czech Republic. In 2005, Dukovany and Temelin Nuclear Power Plants generated 24.7 TWh of electric power.
