Bulgaria has signed a contract with a consortium led by France's EDF and Russia's Rosenergoatom for preparatory works for extending the lifespan of the two 1,000-megawatt (MW) units of its sole nuclear power plant, the government said.
"The first stage of the preparations to extend the lifespan of Kozloduy nuclear power plant's Units Five and Six by up to 20 years has begun," the government said in a statement on Friday.
No details about the financial parametres of the contract with EDF and Rosenergoatom or its timeframe were disclosed.
Kozloduy remained with just two operational reactors after the government closed down four units of 440 MW each to address nuclear safety concerns of the European Union prior to the country's accession to the bloc. Bulgaria joined the EU in 2007.
Earlier this month the government in Sofia decided to add a new unit to the Kozloduy plant, after dropping a project to build a second nuclear plant in the country.
