I was poking around with some mods and thought about this.....

I think it would be neat to have old run down rimatomic parts/props for ancients vaults and gene labs as there power sources. With a fairly good chance for them to be damaged and leaking radiation. (as an option) would be an added danger and would supply an option for getting fuel rods. You could even have a play through where that is the only way you can get fuel rods is ruined vaults/labs/bases.
