Makes vanilla nuclear power recipes more expensive:

Uranium Processing:
1.5x more expensive, slightly lower U-235 yield;
0.5% (1/200) compared to vanilla 0.7% (1/142)

Fuel Cell:
2.5x more expensive, 0.1x yield
requires steel for fuel casing
(fuel cells now cost about 25x more, and take a higher U-235 ratio)

Fuel cell Reprocessing:
slightly lower uranium return (20% of a new cell compared to vanilla 30%)
much longer process (5x longer processing time)
returns 80% of invested steel cell casing

Kovarex Enrichment:
turns U-238 into U-235 at a 5:1 ratio, compared to vanilla 3:1
requires a 25% larger initial U-235 pile to start (50, compared to vanilla 40)

Nuclear Fuel:
now requires 4 Rocket fuel (1/3 of the energy total)
now requires 2 U-235 and 8 U-238

Version 1.1.0 totally refactored the mod, the code actually looks professional now :P
