Uranium and thorium are not stable. They break down in a process called radioactive decay. More than 99% of natural uranium exists in a form (isotope) called uranium-238 while more than 99% of natural thorium exists as thorium-232.Web

Doubling the uranium price (say from $25 to $50 per lb U 3 O 8) takes the fuel cost up from 0.50 to 0.62 ¢/kWh, an increase of one-quarter, and the expected cost of generation of the best US plants from 1.3 ¢/kWh to 1.42 ¢/kWh (an increase of almost 10%). So while there is some impact, it is minor, especially in comparison with the impact of ...Web

Therefore, the cost of thorium in a mixed thorium-uranium LWR fuel or in a pure thorium-233 U fuel cycle is relatively small. However, the cost of chemically processing of ThO 2-based fuel and the separation of 233 U is significant. Energy Content of Uranium and Thorium.Web

Thorium (232 Th) is four times more abundant than uranium in nature and has become a new important source of energy in the future.This is due to the ability of thorium to undergo the bombardment of neutron to produce uranium-233 (233 U).The aim of this study is to investigate the production cost of thorium oxide (ThO 2) resulted from …Web
