It's a nuclear power plant, it is almost fully destructable and can overheat is it's cooling system messes up (the DEUT and detector, which CAN fail a lot, becuase DEUT sucks)
If it reaches a certain temp, the cooling system kicks in and cllos the whole thing down.
It should be very simple, the noble makes pressure, pressure heats Uranium, uranium heats nbole, noble heats brick, brick heats water, water goes round and makes electricity.
