The Explosive Nuclear Question
It's going to be at least another two decades before any commercial models are built, but researchers are at work designing the Generation IV nuclear reactors. Unlike the generation II and III models now in use that use water to cool and control the fission (preventing runaway reactions, subsequent meltdowns and the environmental apocalypse that would result), the leading contender for cooling material for the Gen IV reactors is molten sodium. Not sodium chloride (plain, unreactive table salt), but sodium metal.
2.17.2008 at 07:33pm - Comment by markbart7this would be a great idea (the sodium does not degrade the material as water does), however, there have been problems with it. In the hills around my home town, simi valley, they were experimenting on a reactor like this, and had a radiation leak. This is because the molten sodium needs pumps, which need lubricants to keep working. Some of the lubricant leaked into the sodium, and made it very thick, which gummed up the works.
