Pretty minor overall, but I think it would help players wrap their heads around things better.
Chambers are, realistically speaking, not chambers, and they are not related to the reactor in any way beyond how many blocks you need.
Rename them "Subsystems" or something like that. Its a lot easier to grasp "You build a reactor. You run some power cables over here to your subsystems", IMO. Trying to tie the chambers to the reactors like they're part of the same thing is kinda wonky, conceptually speaking.
