The political part will be handled by Chinese. While The West is sinking into political quagmires, Chinese are building stuff.
I am not on my good network connection so cannot look things up but it would certainly be nice if they worked on some fuel reprocessing and Pu238 production.
India is also working on the thorium cycle reactors (no wonder with their huuuuuge thorium deposits) of which the Pu238 (okay, Np237) is a byproduct.
Hope it won’t take too long…
Also, there is the strontium-90 option that’s highly inferior to Pu238 for a million reasons, but could be at least considered.
