I thought Russia was depending on us to get rid of a lot of spent fuel they had at understaff facilities.Regardless of understaffed, underequipped and poorly guarded facilities (which was much more of a problem in an early-mid 90s than now) this was never the case. We did help Russia with surveillance and monitoring equipment at some of those facilities, however, and also helped them mix down weapon's grade plutonium into a plutonium-uranium mix, which could be used to power reactors, but not to make bombs.
Thanks for the info as to how we worked with the Russians on the earlier on spent fuel rods issue.
