Supercritical - Nuclear Fission for GTCEu

Based on Zalgo's and bruberu's implementation of nuclear fission reactors in GregTech: Community Edition Unofficial, this mod adds fission technology to the game!

Build boiling-water reactors, process spent fuel rods, and recreate Chernobyl!

NOTE: There may be future nuclear fission implementations in GTCEu, with which this mod will be incompatible.
