It is to my understanding that we use dense materials and split them up to get our energy using rods. After this we get a decayed material of what I would guess to be in a spectrum of nickle and silver (half of U238). ?
So I get that nuke waste is still in a decay phase, that atoms are unstable and traveling at high decay rates, that particle mass is emitting neutrons,, AND helium which i found to be interesting.
But if helium is a rare substance why wouldn't we collect it for reuse, is it unstable aswell? and If helium is the result of stabilized neutrons wouldn't that mean that we could Soak nuke wastes in a high PSI hydrogen bath to stabilize it faster?
