Reactor graphite control rods

[cpy]

Idea is simple, you make some graphite rods from coal and you slow down reactor fuel usage. 1 rod = 20MW 50% fuel usage, 2 rods = 10MW 25% fuel usage.

I find that a very interesting suggestion.

Should these controls rods be replaced in regular intervals? Or do they function more like modules that you can put into assemblers, i.e. they never expire?

You probably would need to replace them.
