Nuclear power and nuclear bombs
Another useful summary of the proliferation concerns associated with "peaceful" power reactors from Henry Sokolski of the Nonproliferation Policy Education Center:
At first blush, our government’s approach to head off Iranian nuclear weapons with tighter sanctions and military threats seems totally at odds with its continued effort to negotiate a disarmament deal with Pyongyang. Yet, in one key respect, both of these approaches and a broad swath of bipartisan expertise are quite unified—namely, they support these countries’ continued construction and operation of light water power reactors (LWR) for generating electricity, viewing these reactors as benign. This is not only mistaken but dangerous, and not just in the case of North Korea and Iran.
In fact, civilian LWRs can be copious producers of plutonium suitable for nuclear weapons. The argument one often hears, that the plutonium these reactors produce is unsuitable for simple weapon designs, is simply wrong. The suitability of the plutonium for weapons depends on how long the plutonium-containing spent fuel stays in the reactor. The longer the fuel stays in the reactor the more optimal it is for power production but the less optimal it is for use in nuclear weapons. The common assumption is that the reactor’s owner would not tamper with commercial refueling schedules. This assumption is simply silly.
Nonetheless, Obama administration officials and many of their critics continue to describe LWRs as a safe proposition, so long as they are inspected by the International Atomic Energy Agency (IAEA) and are not accompanied by reprocessing facilities to extract plutonium from their spent fuel or enrichment facilities to produce fresh fuel. This mistaken view got its greatest boost from George W. Bush. No friend of Iran, Bush in 2005 said the United States had no problem with the Bushehr nuclear power reactor—it was just Iran’s centrifuge enrichment technology that concerned us. Indeed, small centrifuge plants that are claimed by owners to be used for producing low-enriched uranium fuel for reactors are a proper proliferation concern because they could also be used to produce highly enriched uranium for bombs. But building a small clandestine reprocessing plant to extract the plutonium from LWR spent fuel is actually easier than putting up a centrifuge plant. Nonproliferation policy hasn’t been taking this possibility seriously enough.
