China has resumed construction on a "fourth generation" nuclear power plant, suspended after the 2011 Fukushima disaster.

China has resumed construction on a "fourth generation" nuclear power plant, suspended after the 2011 Fukushima disaster, which will be its biggest-ever nuclear facility, state media said Saturday.

Construction on the coastal Shidao Bay nuclear plant in Rongcheng, a city in eastern China's Shandong province, resumed last month, the state-run China Internet Information Center reported, adding that the plant is "China's biggest planned nuclear project".

The plant, which will be cooled by high temperature gas, will become "the world's first successfully commercialized fourth generation nuclear technology demonstration project", the report stated.

“It is designed to be safer and cuts down on costs,” the report quoted a spokesman from the China Huaneng Group, the biggest investor in the plant, as saying.

The plant, expected to begin supplying electricity to the grid by 2017, will have a final generating capacity of 6,600 megawatts, the report said, adding initial investment in the project will be three billion yuan ($480 million).

The Shidao Bay plant "has been developed and designed solely by Chinese researchers", the state-run China Radio International said, quoting a China Huaneng Group researcher as saying the company hopes to export the design.

China in October lifted a ban on new nuclear power stations imposed in 2011 after Japan's Fukushima nuclear plant meltdown, when the facility was struck by a tsunami, and will allow construction of a "small number" of coastal nuclear power plants, according to an official report.

There are 15 operational commercial nuclear reactors in China, which has ambitious plans to expand its nuclear industry, with 27 reactors under construction near coastal areas, according to the World Nuclear Association.
