Thorium Nuclear Reactor

I fundamentally object Uranium based nuclear reactors for the environment impact of their decay products and the potential for enriched uranium for nuclear bombs.

Scientists have long known that Thorium is a good substitute.

From wikipedia, 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 comes out of the ground as a 100% pure, usable isotope, which does not require enrichment, whereas natural uranium contains only 0.7% fissionable U-235;
* Thorium cannot sustain a nuclear chain reaction without priming, so fission stops by default.

With Thorium, I may have to change my mind on nuclear reactor as an energy source for humanity.
