45 kg … and 9960 kg
You mean 40 kg and 9960 kg (so the sum is 10000 kg)? <insert "Were you a Putnam Fellow?" joke here>

Actually I meant 45 kg and 9955 kg. I adjusted the numbers several times looking for values which would come out with round-ish quantities but %U235 values in the right ranges for HEU and DU.
