Russia and China agreed on the cost of constructing the second stage of China's Tianwan nuclear power station, the RIA Novosti news agency reported, quoting sources close to the talks.
The construction would cost an estimated EUR1.3 billion, the source said, adding that "expanding the Tianwan station on Russian know-how will mean more Russian fuel supplies, services and such that would cost billions more."
The first of the two light-water reactor power units Russia has built at Tianwan in eastern China was commissioned in June 2007 and the second in September 2007.
China plans a big increase in the number of its nuclear power stations partly due to concerns about global warming but also to reduce its dependence on coal.
