Nuclear power balance pass Part 1

Three vital things when looking at the BIG NUMBERS:

1) IC2 nukes were tuned to be superior to solar power, and the other two followed suit relative to their fuel usage
2) In 2.4.9 I ended up way undertuning these - the 2.4.7 numbers were a lot better (except for BR)
3) The mathematically sound numbers felt off in practice - AtomSci is slightly overtuned on purpose and BR is undertuned, but they should all feel right when playing
