Bah, here you can have nuclear material as long as you're registered and certified for handling. It is somewhat pain in the rear but for a good reason - because otherwise we end up with radioactive garbage in normal trash. In said license you get to specify maximum radioactivity and amount of material as well as means of disposal, processing and storage. Includes auditing. Paperwork, but not that hard to meet - pertains to every x-ray machine out there. Kind of like ISO certification. If you're trying for something big, sure, you won't get it without good reason. Combined with explosives license, you can actually have a nuclear bomb. Just tiny and exploded in very controlled conditions. Big amounts and processing hardware are big deal.
