We all know about the slow motion disaster known as Fukushima and the hazards of nuclear power as seen in that situation but most people don't know, including yours truly, that a viable alternative to the light water reactors like Fukushima does exist, tech that could help make sustainable power at real world levels achievable while getting rid of nuclear waste in cost effective fashion.
Dewan said their reactor would be "walk-away safe," according to IEEE Spectrum. "If you don't have electric power, or if you don't have any operators on site, the reactor will just coast to a stop, and the salt will freeze solid in the course of a few hours," she said. Eric Roston, sustainability editor for Bloomberg.com, discussed more advantages. "Molten salt reactors can tap more energy in fuel and use it for decades, compared with four or five years in reactors today. That means they need less enriched uranium, reducing the risk of fuel being stolen to make bombs. Transatomic's reactor would cost half as much per gigawatt of electricity as conventional reactors, Dewan says."
Overall, according to the company, "Transatomic Power's advanced molten salt reactor … solves four of the most pressing problems facing the nuclear industry: ecological stewardship, public safety, non-proliferation, and cost-efficiency."
