China is likely to launch its largest indigenously built nuclear power project with one-million-kilowatt capacity in the eastern province of Zhejiang, an industry official said on Saturday.

The plan is part of an extension project of the Qinshan nuclear power plant in east China's Zhejiang Province, an official from the China National Nuclear Corporation, a state-owned nuclear energy conglomerate, said.

Experts have approved a feasibility report and the central government is examining the project proposal, safety analysis of plant location and evaluation report of the impact on environment.

"It took us six years and 200 million yuan (USD 25 million) to design the project," Xinhua news agency quoted CNNC General Manager Kang Rixin as saying.

China began developing its nuclear power industry in the late 1980s to help ease the energy bottleneck. In March, the State Council adopted a strategy to promote nuclear power capacity.

The goal is to make the nation's total installed capacity of nuclear power reach 40 million kilowatts by 2020.
