I made this a while ago and never posted it. It converts PLUT into URAN and makes molten PLUT as a byproduct. Everything is automated. STOP will wait until the current process is done before stopping.
I like the design! You can make it more compact by replacing the folded PSCN line timers with a simple DLAY timer. The molten PLUT probably can also be cooled down (use LN2 or still game-of-life) and reused. +1
