So I was planning on building this reactor for my breeder, but I wanted to test it first in creative. I set it up, put in a depleted isotope cell, and it instantly became a reenriched cell. Although the reactor itself can safely go up to 54,000 heat, it was then at 0, so that shouldn't have affected anything. The quad thorium cells give the depleted cell 16 neutron pulses per tic, which is not even close enough to instantly charge it. My only ideas are that either its bugging out and using a massive heat value that the heat plates let the reactor reach, or something about being in creative mode is messing it up. However, i turned of creative and cheat mode on NEI and it still happens.
