Interesting idea, it may work. But then whole my base would be somewhat radioactive. Decisions, decisions…
I’m doing this to get uranium-238 from spent Co-60. To later breed it to Pu-239 to use as real fuel. I modified GT6 to give no uranium through worldgen, including byproducts of byproducts. Fun my way 
Also, no coal/lignite, no coke ovens, no natural gas. Only what nature gives and limited oil. Drained 5 oil pockets so far (of 6 found).
