Thorium As Nuclear Fuel: the good and the bad

Thorium As Nuclear Fuel Thorium is a basic element of nature, like Iron and Uranium. Like Uranium, its properties allow it to be used to fuel a nuclear chain reaction that can run a power plant and make electricity (among other things).

Uranium Wikipedia

Uranium234, which is a member of the uranium series (the decay chain of uranium238), decays to lead206 through a series of relatively shortlived isotopes. Uranium233 is made from thorium232 by neutron bombardment, usually in a nuclear reactor, and 233 U is also fissile.

Thorium World Nuclear Association

Mixed thoriumplutonium oxide (ThPu MOX) fuel is an analog of current uraniumMOX fuel, but no new plutonium is produced from the thorium component, unlike for uranium fuels in UPu MOX fuel, and so the level of net consumption of plutonium is high.

Thorium vs Uranium Nuclear Power

Thorium vs Uranium – Energy Release per Fission. In general, the nuclear fission results in the release of enormous quantities of energy. The amount of energy depends strongly on the nucleus to be fissioned and also depends strongly on the kinetic energy of an incident neutron.

Uranium Thorium Dating UA Geosciences

UraniumThorium dating is based on the detection by mass spectrometry of both the parent (234 U) and daughter (230 Th) products of decay, through the emission of an alpha particle. The decay of Uranium 234 to Thorium 230 is part of the much longer decay series begining in 238 U and ending in 206 Pb.

Uraniumthorium dating

Thorium230 is itself radioactive with a halflife of 75,000 years, so instead of accumulating indefinitely (as for instance is the case for the uraniumlead system), thorium230 instead approaches secular equilibrium with its radioactive parent uranium234.
