BEIJING (AFP) - China intends to build two more nuclear power plants as part of plans to cope with its fast-rising demand for energy, state press says.

The two plants -- one in the eastern province of Fujian and another in southern Guangdong -- will add to the 11 reactors already in operation around the country, state media said.

The nation's biggest nuclear reactor builder, China National Nuclear Corp, and China Huadian Group, one of the country's top five power majors, signed an agreement Wednesday to build the Fujian plant, the China Daily said.

The facility, in Hui'an county, in the southeast part of Fujian, will be able to sit as many as six 1,000-megawatt reactors, the report said.

No timeframe was given for the project.

International bidding will be used to determine whether foreign or Chinese technology will be used, the report quoted a company source as saying.

In a separate report, Xinhua news agency said the Guangdong government planned to add another nuclear power plant to the four already in operation in the province.

China Guangdong Nuclear Power Holding Company signed a cooperation agreement with the Shaoguan city government on Wednesday to build the plant.

The power generating capacity of the new plant is unknown but it will cost 100 billion yuan (12.5 billion dollars), Xinhua said, citing Shaoguan mayor Xu Jianhua.

China's economic planning authorities have previously announced plans to increase the percentage of the nation's total power output from nuclear energy from less than two percent to four power by 2020.

China National Nuclear president Kang Rixin was quoted as saying in the China Daily that the amount of nuclear energy could be as high as six percent of the national total by 2010.

He said as many as 32 more nuclear reactors could be built within the next 15 years.

Coal currently meets 74 percent of China's energy demands.

The government is looking to nuclear and other fuel sources to limit the enormous environmental impacts of heavy coal dependency, as well as to help meet the nation's fast-rising energy demand.
