@lazures 1) Shoot NEUTs into the mix. 2) Keep shooting until all PLUT is LAVA. 3) Put liquid only wall and solid only wall with a divide down the middle. (???) 4) URAN lands in solid only pit, PLUT LAVA lands in liquid only. (PROFIT!) 5) Cool PLUT LAVA with GoL or something similar. 6) You now have a pit of of URAN and a pit of PLUT.
@lazures(View Post) I have this that I designed a while ago, it comes out slightly purified, I'm having trouble with lava slipping into the URAN chamber and not all of the PLUT detonating.
