The Coming Nuclear Crisis

The world's nuclear plants today eat through some 65,000 tons of uranium each year. Of this, the mining industry supplies about 40,000 tons. The rest comes from secondary sources such as civilian and military stockpiles, reprocessed fuel and re-enriched uranium.
"But without access to the military stocks, the civilian western uranium stocks will be exhausted by 2013, concludes Dittmar.
It's not clear how the shortfall can be made up since nobody seems to know where the mining industry can look for more.
That means countries that rely on uranium imports such as Japan and many western countries will face uranium shortages, possibly as soon as 2013.

Uranbrist inom 20-30 år befarar IAEA
Det internationella atomenergiorganet IAEA varnar för att det kan bli brist på uran till alla de nya kärnkraftverk som nu byggs runt om i världen, inom några decennier. I sommar kommer IAEAs nya globala sammanställning av uranläget, men Hans Forsström som är direktör för bränslecykel och avfall på IAEA, säger att tidigare prognoser verkar stå sig.

Idag produceras bara 75% av det uran som konsumeras. Resten av det uran som använd kommer från omvandling från militära kärnvapen till civilt uran.

Power for U.S. From Russia’s Old Nuclear Weapons
But at times, recycled Soviet bomb cores have made up the majority of the American market for low-enriched uranium fuel. Today, former bomb material from Russia accounts for 45 percent of the fuel in American nuclear reactors, while another 5 percent comes from American bombs, according to the Nuclear Energy Institute, an industry trade association in Washington.

The program for dismantling and diluting the fuel cores of decommissioned Russian warheads — known informally as Megatons to Megawatts — is set to expire in 2013, just as the industry is trying to sell it forcefully as an alternative to coal-powered energy plants, which emit greenhouse gases.
