Kozloduy Nuclear Power Plant

From Wikipedia, the free encyclopedia

The Kozloduy Nuclear Power Plant is a nuclear power plant in Bulgaria situated 200 km north of Sofia and 5 km east of Kozloduy, a town on the Danube river, near the border with Romania. It is the country's only nuclear power plant. The construction of the plant began on 6 April 1970.

Kozloduy NPP manages six pressurized water reactors with a total output of 3760 MWe at present. Four are old WWER-440 V230 reactors and, under a 1993 agreement between the European Commission and the Bulgarian government, Units 1 and 2 were taken off-line at the end of 2003. Units 3 and 4 were taken off-line at the end of 2006, immediately prior to the Bulgaria's accession to the European Union. Units 5 and 6, constructed in 1988 and 1993 respectively, are newer WWER-1000 reactors.

Prior to shutdown of units 3 and 4, the plant single-handedly provides Bulgaria with 44% of its electrical demands and allowed the country to export about 20% of its electricity abroad. With just units 1 and 2 taken off-line, Bulgaria, as of March 2006, exported about 14% of its electricity.
