Thorium Energy Viability

Thorium has properties like uranium which allows it to fuel a nuclear chain reaction. But unlike uranium which splits and releases energy, thorium goes through a series of nuclear reactions when exposed to neutrons until it emerges as an isotope of uranium called U-233. This isotope will readily split and release energy next time it absorbs a ...

Uranium:

Uranium-238, the most prevalent isotope in uranium ore, has a half-life of about 4.5 billion years; that is, half the atoms in any sample will decay in that amount of time. Uranium-238 decays by alpha emission into thorium-234, which itself decays by beta emission to protactinium-234, which decays by beta emission to uranium-234, and so on.

It can. However, the decay chain also include Uranium 232, so you always get a mix of Uranium 233 and 232 when using thorium to generate fuel. Uranium 232 is a gamma emitter, and gamma radiation is easy to detect from long distances. Uranium 232 is also very difficult to handle because it is a gamma emitter.

Uranium and Depleted Uranium

Uranium from thorium. Thorium, as well as uranium, can be used as a nuclear fuel.
