Nuclear power generates about a third of electricity in Bulgaria. Bulgaria's first commercial nuclear reactor began operation in 1974.^[1] The Kozloduy NPP operates two pressurized water reactors with a total output of 1906 MW. This makes Bulgaria the 21st-largest user of nuclear power in the world. Construction of the Belene Nuclear Power Plant was officially terminated in March 2012, and a thermal powerplant was supposed to be built on the site.^[2] Efforts in May 2018 to restart the Belene project were unsuccessful. As of 2022^[update], Bulgaria plans to construct new reactors at the existing Kozloduy site,^[3] and at Belene.^[4]

Bulgaria has the Kozloduy Nuclear Power Plant with two pressurized water reactors (together 2000 MW net). Four old and unsafe VVER-440/230 reactors (4 x 408 MW net) were taken off-line in 2004 and 2007). The two active reactors cover almost half of Bulgaria's electricity demand.^[5]
