This is not really an interesting line of discussion because all the relevant regulations regarding classified information, materials handling, and industrial safety would be enough to effectively prohibit possession of nuclear arms, without any reference to arms at all. I'm not sure we even have any laws explicitly prohibiting possession of nuclear weapons -- most of the material I've found so far on the subject in the CFR is about "special nuclear materials".
Most of the interesting policy area regarding the right to bear arms is actually in bearable arms -- small arms and light weapons. Although it is legal to own a tank, for example, this is not of much practical impact.
