USA has some Uranium-233 stored, but they’re going to destroy it by blending it with U-238. U-233 is valuable, it takes a lot of effort and energy to produce it (have Thorium-232 absorb a neutron) and it is the fissile material for LFTR reactors (of which I’ve blogged about before). It is especially important for starting a lot of LFTR reactors easily.
I’ve also heard the U-233 stock it is also useful for medical isotopes.
I’m not in the US, but if you are. please read more about the case and tell other people about it, this needs to be known and stopped before it happens.
Kirk Sorensen has blogged extensively about it, and there is going to be a letter writing campaign for political representatives.
