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.

Most if not all Ontario and Quebec have been using nuclear energy for long time, also Canada is one of the top uranium producer if I remember it right.

I dunno about Quebec, but Ontario is definitely not entirely reliant on nuclear power. It is the largest form of power generation in the province (using Canada's very own CANDU reactors, no less), but it still amounts to less than 50% of Ontario's electricity generation. The province uses a large number of fossil fuel (eg. coal), natural gas, and hydroelectric power stations, as well as some alternative energy power stations as well.
