Uranium–thorium dating (Redirected from Uraniumthorium dating) Uranium–thorium dating, also called thorium230 dating, uraniumseries disequilibrium dating or uraniumseries dating, is a radiometric dating technique established in the 1960s which has been used since the 1970s to determine the age of calcium carbonate materials such as speleothem or coral

India’s Kakrapar-1 reactor is the world’s first reactor which uses thorium rather than depleted uranium to achieve power flattening across the reactor core.

Debate: Thorium or Uranium? Debate
2014-3-26 Uranium can be mined from sedimentary rocks, igneous deposits, and seawater and thorium is mainly mined from rocks and soil. Both have good mining possibilities. The statement that "thorium is much more abundant" is misleading. If we look at the crustal abundance, thorium has abundance between 6 and 9.6ppm.

Thorium is much more abundant in nature than uranium. Thorium can be used as a nuclear fuel through breeding to uranium-233 (U-233). When this thorium fuel cycle is used, much less plutonium and other transuranic elements are produced, compared with uranium fuel cycles. Several thorium-fuelled reactor concepts are under consideration.

Thermal ice storage, batteries, and a slew of other options included. This dynamic seems to reinforce the cost delta rather than eliminate it.
