In physics, what makes power plant grade uranium, is the uranium 235 isotope. Since the uranium we mine isn't mostly 235, they have to enrich the the uranium ore. This enrichment process is also used to enrich the weapons grade uranium. This is why the Atomic energy commision (or whatever it's called) restricts what countries can have nuclear power plants.
I hope I remembered correctly, it's been forever since I took physics.
