No, I'm not saying that we should not use Thorium at all. I'm saying that the internet claim that thorium reactors cannot be used to make bombs is patently false. It bothers me that there is misguided understanding of thorium that ends up trashing advanced nuclear in general in favor of thorium.

There are 2 true benefits to thorium over thorium: less long-lived transuranics (but more deeply-penetrating 2.6 MeV gammas from Tl-208) and the ability to have a breeder with slow neutrons (less specific fissile inventory, but more problematic graphite).

The major health threat from any nuclear reactor is large early release dose, which is proportional to power level and power level alone (Watts is proportional to number of atoms fissioning per second). In this, Thorium fuel is very similar to Uranium fuel. Long-term waste ends up in a deep geologic repository in any case. Uranium-Plutonium cycle can breed as well or better than the Thorium-Uranium cycle.

I like thorium a lot. I just don't want people relying on stuff that is factually incorrect to promote it. It's easy to promote without being wrong.
