Dukovany Nuclear Power Station

The Dukovany Nuclear Power Station is a nuclear power plant (NPP) near Dukovany, a village in the Czech Republic.It was the first NPP in what is now the Czech Republic (the Bohunice Nuclear Power Plant in what is now Slovakia was constructed in 1958) and is situated from the city of Třebíč, near the Dalešice Reservoir, where the NPP sources its water supply. In 1970 Czechoslovakia and the Soviet Union ratified a contract for construction of two NPPs. Actual construction work began four years later. From 1985 to 1987, four power units with pressurized water reactors were commissioned. All four are still in operation.In 1994, a tourist centre was opened at the site.Dukovany NPP annually supplies approximately 14 TWhr of electric energy to the national power network. NPP is owned and operated by CEZ Group. The power plant modernisation will successively be carried out to the end of its planned service life.Technical dataThe Dukovany NPP has four reactors. As of December 31, 2011 CEZ reported turbine generator output (gross capacity) as listed below. Net capacity is a baseline estimate only.In 2005, Unit 3 was upgraded to 456 MWe gross capacity, and the same upgrade was made to Unit 1 and Unit 4 in 2007. Unit 3 was further upgraded in 2009 to 500MWe. In total an extra 240 MWe of capacity has been or will be added before 2013 in a comprehensive program of improvements including steam plant replacement, addition of instrumentation and fuel changes.
