Bulgaria's energy minister said the government 
is proposing to US-based Westinghouse, controlled by Japan's Toshiba Group, to 
acquire a 49% stake in a planned 1,000 MW unit at the country's sole nuclear 
power plant (NPP) Kozloduy, local media reported on Thursday.
The 
Bulgarian government signed last year with Westinghouse a shareholder agreement 
for the construction of the new Kozloduy unit, under which the US company would 
provide all of the plant's equipment, design, engineering and fuel and will 
issue a competitive tender for the construction of the unit.
By becoming 
a strategic investor the project, Westinghouse will also ensure 49% of the 
financing needed for the NPP unit's construction, online portal Investor.bg 
quoted Temenuzhka Petkova as saying.
Petkova also said that the 
exclusivity of the agreement signed with Westinghouse is due to expire on March 
31. However, negotiations with the US company regarding the project will 
continue after that, as well.
The Kozloduy NPP was left with two 
operational reactors of 1,000 MW each after the country closed down four units 
of 440 MW each to address nuclear safety concerns expressed by the European 
Union prior to Bulgaria's accession to the bloc in 2007. Bulgaria plans 
extension of the lifespan of the 1,000 MW units 5 and 6 of the Kozloduy 
NPP.
In April 2012, the government in Sofia decided to add another 1,000 
MW unit to the plant, a project that is currently taking shape. US-based 
Westinghouse, controlled by Japan's Toshiba Group, said in August last year a 
shareholder agreement following consultations with all Bulgarian political 
parties for the construction of a new unit at the NPP. The AP1000 reactor is 
projected to be online by 2023.
