Doubts raised on nuclear industry viability


A scientist from the Swiss Federal Institute of Technology predicts that supplies of are running out and countries relying on imports of uranium may face shortages by 2013, while a New York Times journalist suggests new nuclear power plants are an "abysmal" investment that will never pay for itself without government financial support.

Dr Michael Dittmar, a physicist with CERN (the European Organization for Nuclear Research), said in the fourth and final part of an essay on the world's nuclear industry published this week that civilian stockpiles of uranium could be depleted by as early as 2013.

According to Dittmar civilian and military stockpiles and re-enriched or reprocessed uranium sources contribute 25,000 of the 65,000 tons of uranium used globally each year. The rest is mined directly, but Dittmar claims nobody knows where the mining industry can find enough uranium to make up the shortfall, and disputes the Nuclear Energy Agency's estimates of reserves of Uranium.

Dittmar is unconvinced that fission breeder reactors can provide a solution, saying that their inefficiency, high construction costs and poor safety mean they are unlikely to become commercially viable alternatives. He considers even less likely to provide the needed energy.
