Unformatted text preview: y/cheap deposits Estimate about 3 million tons available at cost < $230/kg •  Need 200 tons per GW-yr •  Currently ~100 GW of nuclear power generation globally (about 100 plants of 1 GW each) •  3 million tons will last 150 years at present rate…. but only 30 years if nuclear replaced all electricity production Where do we find minable uranium? Formation of UO2 geological deposits U soluble when oxidized (+6) UO2 forms when reduced (+4) So find UO2 precipitate at natural redox boundaries Where do we find minable uranium? Formation of UO2 geological deposits A UO2 roll front deposit in an open-pit mine in Wyoming In-situ mining of UO2 deposits by leaching In-situ leaching “reverses” natural deposition process by using an oxidizing fluid Where are the global U resources? Reserves 2011 Production Australia 31% 9% Kazakhstan 12% 30% Canada 9% 15% -------------------------------------------------- US (9th, 8th) 4%...
