General Atomics is launching a 12-year program to develop a commercial reactor that runs on nuclear waste:
The General Atomics reactor, which is dubbed EM2 for Energy Multiplier Module, would be about one-quarter the size of a conventional reactor and have unusual features, including the ability to burn used fuel, which still contains more than 90% of its original energy. Such reuse would reduce the volume and toxicity of the waste that remained. General Atomics calculates there is so much U.S. nuclear waste that it could fuel 3,000 of the proposed reactors, far more than it anticipates building.

The EM2 would operate at temperatures as high as 850 degrees Centigrade, which is about twice as hot as a conventional water-cooled reactor. The very high temperatures would make the reactor especially well suited to industrial uses that go beyond electricity production, such as extracting oil from tar sands, desalinating water and refining petroleum to make fuel and chemicals.
The technical hurdles are dwarfed by the regulatory hurdles:
High-temperature reactors place special stress on the metals used in reactor components, and there isn’t any commercial certification process at the NRC to assess the reactors’ unique characteristics and to verify that they could operate safely for an expected 40- to 60-year life. That process would need to be developed or such reactors couldn’t be certified.The regulatory agency would also have to decide how to handle license requests from companies that might want to locate reactors near industrial facilities, such as oil refineries, something that current regulations don’t contemplate and that could pose special safety risks in the event of an industrial fire or explosion.
General Atomics was founded in 1955, by the way, when a name like General Atomics seemed perfectly natural.
