Some benefits of thorium fuel when compared with uranium were summarized as follows:
Weapons-grade fissionable material (233U) is harder to retrieve safely and clandestinely from a thorium reactor;
Thorium produces 10 to 10,000 times less long-lived radioactive waste;
Thorium mining produces a single pure isotope, whereas the mixture of natural uranium isotopes must be enriched to function in most common reactor designs. The same cycle could also use the fissionable U-238 component of the natural uranium, and also contained in the depleted reactor fuel;
Thorium cannot sustain a nuclear chain reaction without priming, so fission stops by default in an accelerator driven reactor.
When used in a breeder-like reactor, however, unlike uranium-based light water reactors, thorium requires irradiation and reprocessing before the above-noted advantages of thorium-232 can be realized, which initially makes solid thorium fuels more expensive than uranium fuels. But experts note that «the second thorium reactor may activate a third thorium reactor. This could continue in a chain of reactors for a millennium if we so choose.» They add that because of thorium's abundance, it will not be exhausted in 1,000 years.
Вот, короче читайте википедию. ☺ Я тут не всё до конца понимаю, но походу этот ториум не может сам по себе поддерживать цепную реакцию.
