There are Faster, Cheaper, Safer and More Reliable Alternatives to the Energy Department’s Proposed Multibillion Dollar Test Reactor

, Acting Director, Nuclear Safety Project; Senior Scientist, Global Security Program

Department of Energy (DOE) Secretary Rick Perry recently announced the launch of the Versatile Test Reactor (VTR) project, flagging it as one of the department’s top priorities. The project, which would be the first new DOE test reactor in decades, would differ from the DOE’s operating test reactors because it would be cooled by liquid sodium instead of water, enabling it to produce large numbers of “fast” neutrons. The DOE says that such a facility is needed to develop new reactors that use fast neutrons to generate electricity. US nuclear plants today are light-water reactors, which use slow (“thermal”) neutrons.

The Union of Concerned Scientists (UCS) questions the need for a dedicated fast neutron test reactor and, more generally, has serious concerns about fast reactor safety and security, detailed in a critique it released last year. Fast reactors pose nuclear proliferation and terrorism risks in part because they commonly use fuels containing plutonium, a nuclear weapon-usable material. Most fast reactor concepts also involve reprocessing of their spent fuel, which separates plutonium in a form that is vulnerable to theft. Read more >

NRC Cherry-Picking in the Post-Fukushima Era: A Case Study

Mark Leyse, , UCS

In the late 1960s, the Atomic Energy Commission (AEC), the forerunner of the NRC, paid the very companies that designed nuclear reactors—Westinghouse and General Electric (GE)—to test the efficacy of their own emergency cooling systems. Read More
