> None? It is France. They already have nuclear weapons. But while we're talking about it, Megatons to Megawatts[2] has been the best deproliferation project in history, reducing the number of nuclear warheads by over 20,000.
More nuclear trained personnel, designs, materials, and plants mean more opportunities for someone to acquire technology or materials.
I'm sorry, but you're just spreading FUD. There's a reason the Iran Deal is a fine deal. But I don't expect anyone to understand this without 1) reading the fucking thing and 2) actually understanding nuclear physics and reactor design (this should be rather unsurprising, but for some reason everyone thinks they are qualified on this matter). I suspect you don't meet either qualification, given your comment.
So with the Iran deal, what do we have? Well they would have needed around 3-6mo to enrich their stockpile for enough material for a single weapon. Something they haven't done before and do not have the technology to do. Also something they did not appear to be attempting to do.
But I talked about consensus. I'd say Nature is a good source for that[0]. You'll note here that Nature is talking about getting enough enriched material in months but several other news sources I looked at used the phrase "build a weapon" instead. I'd call this fear mongering and misunderstanding the science.
I'm not trying to tell you that you're dumb, but rather that this is a complicated matter and that amateur levels of understanding aren't quite enough to even get the basics. I have a degree in the field, have worked in the industry and in energy departments. My level of understanding is barely enough to get the basics. I'm calling you out because we're talking about something extremely complicated that people vastly overestimate their expertise to handle. Atomic physics is not a simple thing where you can get a basic understanding through even months of googling.
If a big country like France can handle guarding hundreds of small nuclear weapons, they can certainly handle guarding nuclear fuel in small number of additional NPPs. We are not talking about building NPPs in every small town guarded by incompetent local volunteers. Trained armed personnel and accountability of processes and personnel in few facilities can prevent this risk.
