This article, and the Chernobel incident along with the 3 mile Island incident has prompted me to as this question.

It also mentions the BWR reactors (like 3 mile Island :-). There are also the Sodium (or "breeder") Reactors which run even hotter than graphite? What about the Fort St Vrain "argon/freon" reactor in Colorado? Is this design any safer? Is the Ft. St. Vrain reactor info included in descriptions of reactors? Are there any other such reactors? What other options are available to make a really safe reactor? Would smaller reactors be better than large ones? I'm curious as to whether the "Boiling water is best" approach taken by the navy in their "boat powerplants" is really apropriate in the context of large plants, often located near populated areas. I often wonder if safety is really a primary consideration when these plants are designed (It was for Ft. St. Vrain). If smaller piles, or "self feeding half/breeders" are better than BWR, are there ways to more efficiently convert fission energy into other forms of energy? Are there any materials or elements which become "unradioactive" when they are removed from the core cirulation (Argon?). If a truly safe design were possible, would it be less costly in terms of legal hassles to use this, rather than a cheaper but more contriversial BWR design? Obviously, I don't know much (anything) about nuclear physics, but it would be nice to know if this form of energy could be used more safely in other ways. I was living in Colorado when the Three Mile Island plant went nuts, and the issue was raised. Public Service Company spokesmen pointed out that they had rejected a number of "popular" designs because they didn't believe they were "safe enough". Was this just PR, or is the argon/freon design really safe?
