China says it can reprocess spent nuclear fuel

Yahoo News 3 Jan 11;

BEIJING (AFP) – Chinese scientists say they have developed nuclear fuel reprocessing technology that could effectively end uranium supply concerns, state media said Monday, as Beijing strives for energy security.

The technology, developed by state-run China National Nuclear Corp (CNNC) in the remote northwestern province of Gansu, enables the country to re-use irradiated nuclear fuel, China Central Television said.

"China's proven uranium sources will last only 50 to 70 years, but this now changes to 3,000 years," said the report, which provided scant details on what it described as a "breakthrough."

Other countries have already developed technology to reprocess spent fuel, which is extremely costly.

"Globally, within the nuclear fuel industry, we're one of a minority of countries that can do the nuclear fuel cycle," Sun Qin, general manager of CNNC, was quoted as saying in the report.

The development would be an important step forward in China's plans to increase the share of alternative power sources in its energy mix to reduce pollution and achieve energy security.

It has stepped up investment in nuclear power in an effort to slash carbon emissions and scale down the nation's heavy reliance on polluting coal, which accounts for 70 percent of its power needs.

China, now the world's second-largest economy after surpassing Japan in 2010, aims to get 15 percent of its power from renewable sources by 2020.

It aims to increase nuclear power capacity to 70-80 gigawatts by 2020, accounting for about five percent of the country's total installed power capacity, state press reports have said.

The government said previously the target was 40 gigawatts.

China, which currently has 13 nuclear reactors in operation, produces around 750 tonnes of uranium a year but annual demand could rise to 20,000 tonnes a year by 2020, the China Daily newspaper has said.

China Boasts Breakthrough In Nuclear Technology

Chinese scientists have made a breakthrough in spent fuel reprocessing technology that could potentially solve China's uranium supply problem, state television reported on Monday.

The technology, developed and tested at the No.404 Factory of China National Nuclear Corp in the Gobi desert in remote Gansu province, enables the re-use of irradiated fuel and is able to boost the usage rate of uranium materials at nuclear plants by 60 folds.

"With the new technology, China's existing detected uranium resources can be used for 3,000 years," Chinese Central Television reported.

China, as well as France, the United Kingdom and Russia, actively supports reprocessing as a means for the management of highly radioactive spent fuel and as a source of fissile material for future nuclear fuel supply.

But independent scientists argued that commercial application of nuclear fuel reprocessing has always been hindered by cost, technology, proliferation risk and safety challenges.

China has 171,400 tons of proven uranium resources spread mainly in eight provinces -- Jiangxi, Guangdong, Hunan, Xinjiang, Inner Mongolia, Shaanxi, Liaoning and Yunnan.

China is planning a massive push into nuclear power in an effort to wean itself off coal, the dirtiest fossil fuel. It now has 12 working reactors with 10.15 gigawatt of total generating capacity.

China has set an official target of 40 gigawatts (GW) of installed nuclear generating capacity by 2020, but the government indicated it could double the goal to about 80 GW as faster expansion was one of the more feasible solutions for achieving emissions reduction goals.

As such, China will need to source more than 60 percent of the uranium needed for its nuclear power plants from overseas by 2020, even if the country moves forward with a modest nuclear expansion plan, Chinese researchers say.
