Nuclear Reactors As Art 118
Hemos recommends the coverage over at Wired of a project to digitize nuclear reactor art. "Not all nuclear reactors are built alike. Power plant designs can vary in their fuels, coolants, and configurations, a fact beautifully illustrated by a series of reactor wall charts originally published in issues of Nuclear Engineering International during the 1970s and 1980s. Since then, the charts have been lovingly collected by Ronald Knief, a nuclear engineer at Sandia National Laboratory. Recently, he completed his collection... and began to digitize the drawings. The first eight out of more than 100 have now been permanently archived online... 'This is not a CAD/CAM-type thing,' Knief said. 'This really is art.'"

*blinks* Oh how you would have failed my fuel cycles class. Plutonium is present in spent fuel from even non-breeder reactors. Though it only represents 1% or so of the spent fuel, there are some potential advantages to using plutonium from spent fuel over highly enriched uranium. Plutonium can be extracted chemically from spent fuel while U235 can not be separated from U238 without enrichment facilities. The process of chemically removing the plutonium requires much less infustructure than enrichment of uranium. That being said, the byproducts are much more of a nuisance. Still, if a country wanted to claim to be using nuclear technology for power while steadily stockpiling weapons grade material, a power reactor and PUREX-like (Plutonium - URanium EXtraction ) reprocessing system would be one way to do it. That is why there have always been such large concerns over PUREX reprocessing.
One type of power reactor could be of particular interest to countries wishing to produce weapons grade material without performan ANY enrichment. Those are natural-uranium reactors which burn un-enriched uranium as their fuel. They require moderation by heavy water though, which tends to offset some of the cost benefits of not requiring enriched material. Still, being able to use only mechanical and chemical processing of uranium ore and leaving out the whole enrichment step does have its advantage. That is probably why India produced its plutonium through chemically reprocessed spent-fuel from a natural uranium reactor (CIRUS). That's also probably why Iran built a heavy water plant near Arak and is currently building a 40MW light-water moderated reactor as well. This is not a power reactor of course but is not particularly special. The reason a reactor like this would be used instead of a larger scale power reactor is because it is much cheaper if you leave off all those multi-million dollar power side components like tubrines and don't have to scale the system up to something that can light a city. To argue that "conventional" reactors can not be used to produce weapons grade fuel is incorrect. While most reactors used to do so are not power reactors, they are also not particularly unconventional in any way that makes them more difficult to build. In fact, they can be built much more cheaply than a power reactor and with a much smaller footprint.
requires exceptionally precise and expensive equipment and a lot of technical know-how to develop several key components to creating a conventional nuclear device.
This part is true enough for some of the more efficient bomb designs like those that evolved from "Fat Man." While one can use a technically simple gun-type bomb with highly-enriched uranium, this is not practical for a plutonium bomb. If a country wants to use plutonium from spent fuel then they must decide between a more technically challenging design with higher efficiency or a simple but low efficiency device like a two-point linear implosion bomb. The latter is not particularly appealing for a large scale and long term weapons program due to the relatively low yield, but has been considered a potential "suite-case nuke" design since it can be built to an extremely small diameter That definately doesn't sound like a design someone worried about terrorism would be concerned with, right?

Within each of the suppliers the designs were similar; the problem came in when the utilities specified the units. Some wanted big, some wanted small. Some wanted X, others wanted Y. So the suppliers competed against each other within that specification, but no 2 utilities had the same specs. Then they'd submit each individual design to the NRC, who would do a de novo analysis on each individual design and license it.
Should they have simply licensed 1-2 designs and be done with it? In retrospect, yes, but keep in mind that, at the time, the governmental style in the US and France were quite different.
