In this case I hope it won't be useful to generate even more EU / ura, but only to craft the nuke, because otherwise everybody would use it uracells and turns it into Plutonium cells. Maybe I misunderstand and it was meanted to be produced from depleted Plutonium cells ?
What I was talking about was a machine that uses EU to breed Plutonium from uranium, but that was my first idea. Then i came up with the idea of having a plutonium as a possible byproduct (Like Depleted uranium cells from uranium), and then the idea of it only having a chance to happen when next to a possible reactor component, a "deuteron reflector". I think he is talking about "Plutoniumbreedingcells" being the byproduct of uranium like depleted uranium cells.
Edit: They create heat, but not EU
