China fuel breakthrough

Chinese scientists have made a breakthrough in nuclear fuel reprocessing technology that could effectively end any uranium supply concerns, state media reported on Monday.

The technology developed by state-run China National Nuclear Corp 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.

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 reduce the nation's heavy reliance on polluting coal, which accounts for 70 percent of its power needs.

China announces nuclear fuel break


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.

China 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 currently produces around 750 tonnes of uranium a year but annual demand could rise to 20,000 tonnes a year by 2020 as it boosts nuclear power output, the China Daily newspaper has said. - Sapa-AFP

This sounds like another technology win for China, another New Year present for the western bashers.

China has followed in the routes of Russia, India and Japan after announcing its understanding on how to reprocess nuclear fuel. The industrial secret in largely kept separate from others, though it enables each country to separate unused materials during the creation of nuclear energy to create additional power sources. This process will give China an unprecedented amount of untapped energy sources, providing them with the ability to power its large economy.

During the process of creating nuclear energy, any unused uranium and plutonium can be used as their own power sources, reducing waste and providing various additional proponents of energy sources. Typically plutonium is used during this process, but uranium is also capable of providing an additional energy source during price increases.

The process, though effective is finding energy alternatives, is also highly controversial as plutonium is a main component in creating nuclear weapons. Already an owner of nuclear weapons, the potential that this discovery holds could magnify the Chinese possession of nuclear fuel to more than 3000 years. The company that made this discovery claims this fuel can last up to 70 years as is.

At this point in time, China has over a dozen nuclear plants but has yet to commercialize on this process. Already their uranium reserves, according to the China Daily, stands at 171 400 t in the areas of Jiangxi, Guangdong, Hunan, Xinjiang, Inner Mongolia, Shaanxi, Liaoning and Yunnan. This unique recycling technology was discovered at the China National Nuclear Corporation’s No. 404 Factory in the Gobi desert of Gansu province. China currently produces around 10, 15 gw.

Yeah!! China rocks!

2011 is the year of China ..

Yeah .. Yeah ..

Good to know!

Oil price drops?

but as said, other countries already know how to recycle it. so..

The article mentioned Russia, India and Japan know the technology. Probably Canada, UK and the US do not know how to do it. It is questionable whether India knows the technology since it cannot even build its own nuclear power plant.

Moron,

Next time, do a little more research before your start spewing shxt from your mouth la~

中國核能技術突破 鈾儲量用多3000年

【明報專訊】中國核能科技取得重大技術突破,成功開發核燃料循環利用技術,將把鈾的利用率提高60倍之多,大幅提升中國核能儲備,由於此前中國已探明的核能儲備(鈾資源儲量)最多只用70年,現在就足以使用3000年之久。

鈾利用率提升60倍

中央電視台報道,中國核工業集團成功研製出「乏燃料後處理技術」,即能從已不能再用於發電的核廢料中,繼續利用鈾、鉮(同「不」音)等燃料的能量。專家稱,核能發電是通過核燃料在核反應爐中發生裂變反應,釋放出能量。當核燃料功率明顯下降時,燃料就需要更換,被換出的核廢料叫「乏燃料」,類似「煤渣」。據知,在當今核電技術下,核燃料只釋放了3%至4%能量,就因功率明顯下降變成「廢料」,進入可長達數萬年的衰變過程,緩慢釋放剩餘能量。

輻射極強 費用高昂

由於目前核電站對鈾的利用率僅1%,但新技術可將利用率提高至60%以上,意味覑在現有核電規模下,中國已探明的鈾資源本來只夠用50至70年,但未來可足夠使用3000年之久。然而,該技術包括有極強核輻射、對人體有致命傷害的元器件進行剪切、分離、提取、提純等工序,技術精度要求高,且費用昂貴。目前已掌握該技術且高度保密的有英、俄、法、日、印等國,中國科學家經過24年才獲得。

報道引述中國核工業集團總經理孫勤的評價說,「在國際上對整個技術水平、科技水平,我們將能夠擁有話語權,甚至還能起到一定的引導作用。」中國計劃在2020年前把核能發電量提高到700至800億瓦,佔全國發電量的5%。中國目前能生產750噸鈾燃料,但年需求在2020年前很可能上升至2萬噸。

Given the radiation risks that are involved, I certainly hope we wouldn't hear of another nuclear radiation leak from the Grandfather. However, the 大亞灣 accidents (and subsequent cover-ups) certainly are not confidence-inspiring.
