Sentences with phrase «uranium fuel per»

M.I.T. nuclear engineer Charles Forsberg, another co-chair of the report, noted that a typical light - water reactor in the U.S. needs 200 metric tons of mined uranium resulting in 20 metric tons of uranium fuel per year.

Not exact matches

It turns this into enriched uranium, to be re-used in fuel, earning between $ 20 and $ 30 million per year.

Reactors around the world require their fuel to hold anywhere from 3 to 5 percent U235, or 30 to 50 atoms of the fissile isotope per 1,000 atoms of uranium.

With 436 reactors worldwide consuming 65,000 metric tons (one metric ton equals 1.1 U.S. tons) of enriched uranium per year, demand for this nuclear reactor fuel outstrips available supply, which has caused uranium prices to jump from a low of $ 10 per pound a few years ago to more than $ 130 per pound in 2007 and still more than $ 50 per pound today.

Olli Heinonen of Harvard University calculates that it would take Iran six months to make enough weapons - grade, 90 per cent uranium - 235 for a bomb from the 3.5 - per - cent fuel - grade uranium it makes at Natanz under UN surveillance, but only a month starting from 20 - per - cent.

The reason is easy to understand: renewable fuels are energy - diffuse, meaning that there is very little energy per unit of mass compared to both fossil fuels and uranium.

Actually, if you properly do the math - and count if you count the whole nuclear fuel cycle, not just the power plant, not just the core of the reactor, but the occlusion zone, the uranium mining and so on, it turns out that wind power uses hundreds or thousands of times less land per kilowatt hour, then nuclear does.

... it appears that there exist within minable depths in the United States rocks with uranium contents equivalent to 1000 barrels or more of oil per metric ton, whose total energy content is probably several hundred times that of all the fossil fuels combined.
