Correct. The problem is that the fuel cycle involves stages where you have large amounts of plutonium sitting around for long periods of time. Ironically enough, it's also mastery of that fuel cycle that enables the neutralization of weapons-grade material. France has mastered this cycle, and they're one of a few nations who are capable of reprocessing nuclear weapon primaries.
