Separative work – the amount of separation done by a Uranium enrichment process – is a function of the concentrations of the feedstock, the enriched output, and the depleted tailings; and is expressed in units which are so calculated as to be proportional to the total input (energy / machine operation time) and to the mass processed.
Given sufficiently high uranium prices, it is feasible for reprocessed uranium to be re-enriched and reused. It requires a higher enrichment level than natural uranium to compensate for its higher levels of 236 U which is lighter than 238 U and therefore concentrates in the enriched product. [ 3 ]
Doubling the price of uranium would add about 10% to the cost of electricity produced in existing nuclear plants, and about half that much to the cost of electricity in future power plants. [53] The cost of raw uranium contributes about $0.0015/kWh to the cost of nuclear electricity, while in breeder reactors the uranium cost falls to $0.000015 ...
Uranium prices are in for 2012, and costs continue to head higher. The magic molecule's price tag is up over 400% in the past decade and could continue to cut into your dividend stocks' profits in ...
The average spot price of uranium oxide (U 3 O 8) increased from $7.92 per pound in 2001 to $39.48 per pound ($87.04/kg) in 2006. [7] In 2011 the United States mined 9% of the uranium consumed by its nuclear power plants. [8] The remainder was imported, principally from Russia and Kazakhstan (38%), Canada, and Australia.
Recovery of uranium from phosphates is a mature technology; [85] it has been used in Belgium and the United States, but high recovery costs limit the use of these resources, with estimated production costs in the range of US$60–100/kgU including capital investment, according to a 2003 OECD report for a new 100 tU/year project. [87]
Ores were treated in a local ore mill, five miles (8.0 km) east-northeast of Maybell, during the 1953–1964 period; during 1976–1981, ore was heap-leached, and the eluate trucked to Wyoming for uranium recovery. Total production of the district was 5.3 million pounds (2.4 million kilograms) of uranium oxide. [26]
PUREX (plutonium uranium reduction extraction) is a chemical method used to purify fuel for nuclear reactors or nuclear weapons. [7] PUREX is the de facto standard aqueous nuclear reprocessing method for the recovery of uranium and plutonium from used nuclear fuel ( spent nuclear fuel , or irradiated nuclear fuel).
