I'm a little confused here and maybe someone can help straighten me out. I built the Mk X Breeder in the heating config so as to get temp up to 9k or so, as I'm led to believe is necessary for a breeder. I put in the coolant, IHD and reactor plating first, then the 8 depleted cells. Temp goes up to 3 or so. Then I put in the 4 uranium cells and within a few seconds the depleted cells turn into re-enriched cells. I can take them out and put in more depleted cells and those too change to re-enriched cells within a few seconds. Is this the way it's supposed to work? If so, why go through the risk of meltdown at 9k heat?
