Thorium bombs are not possible?

No, Thorium bombs are not possible, but there is a weapon hidden in the Thorium reactor scheme.

When Thorium captures a neutron, it eventually converts to Uranium 233. Just like the more widely known U-235, this is a fissile material which can be made into nuclear weapons.

And, separating U-233 from Thorium is easy compared to separating U-235 from U-238.

Hmmm, but what sort of quantities do you get?

100 Lb. of Thorium yields ? U-233?
Over what time frame?

Would it be an efficient source for U-235?

What’s the fission cross section for U-233? IOW, will it burn up in the core along with the thorium?
