No, that's wrong. The claim is that the bred U-233 will be contaminated with U-232, which is very hard to get rid of, and has the hard gamma emitter Thallium-20

No, that's wrong. The claim is that the bred U-233 will be contaminated with U-232, which is very hard to get rid of, and has the hard gamma emitter Thallium-208 in its decay chain.
- tkeller 16y agoWhere would the U-232 contamination come from, if it's bred U-233? Does thorium also just sometimes decay into the lighter isotope?
- pjscott 16y agoSometimes the thorium, when it absorbs a neutron, will emit two neutrons and turn into thorium-231, which decays (though a couple more isotopes) into U-232. It can also be formed when U-233 absorbs a neutron and emits two, forming U-232. How hard this would be to separate depends on the type of LFTR design you're using. However, you could also include some thorium-230 in the fuel mix to denature any protactinium produced, so there's really no way around having U-232 mixed with the bred U-233. Here's a blog post with more details on the entire process: http://energyfromthorium.com/2006/10/06/denaturing-thorium-with-ionium/ http://energyfromthorium.com/2006/10/06/denaturing-thorium-w...
