I'm a nuke. The real problem with thoriuom is momentum and the waste stream. We are already built on a uranium fuel cycle and it is massively expensive to change.

Plus the crazy dose rates from the waste means that all the waste has to be remote handled behind insane shielding. It's like comparing a long burning candle (uranium waste stream) to a shorter burning but flaming tree (thorium waste stream). I know that the half-life of the hottest isotope (Tl-208) is only 3 minutes but most people forget that there are always new ones on the way thanks to the u-233 decay. It's similar to Sr90. We have a saying when it comes to calibration sources that we buy the Sr90 but get the Y90 for free. It essentially doubles the activity.

I support thorium research but we can do the same exact thing with u-238 and Pu-239. And yes, thorium products (u-233) can be used to make weapons. That argument is bunk right off the bat.
