Bulgaria to Shut Down Two Oldest Reactors

LCG, July 14, 2000--The government of Bulgaria, in a bid to enhance its acceptance into European Union membership, agreed yesterday to shut down the two oldest reactors at its 3,760 megawatt Kozlodui nuclear power plant.

Kozlodui, located on the Danube River about 125 miles north of Sofia, is Bulgarias only nuclear power plant, but provides about 40 percent of the countrys electricity. It consists of four 440 megawatt "old-style" Soviet reactors built without containment buildings and two 1,000 reactors that are more modern but still of Soviet design. The older reactors are considered by Western authorities to be unsafe.

Bulgaria had originally planned to phase out the four older reactors between 2004 and 2012 when they reached 30 years of age, but when the EU invited the country to begin talks which would lead to membership in the European Union, it was made plain that early closure of the older reactors would be a condition.

The EU has said it would provide Bulgaria with 200 million euros ($187 million U.S.) by 2006 to cover closure costs of the old reactors and to lend 250 million euros ($236 million) to bring safety systems at the 1,000 megawatters up to western standards.

Plant officials at Kozlodui say decommission costs for two of the older reactors could cost as much as $400 million.
