Small Modular Nuclear Reactors for the Clinch River, Tennessee


Near the banks of the Clinch River in eastern Tennessee, a team of engineers will begin a dig this month that they hope will lead to a new energy future.

They'll be drilling core samples, documenting geologic, hydrologic, and seismic conditions—the initial step in plans to site the world's first commercial small modular nuclear reactors (SMRs) here.

Once before, there was an effort to hatch a nuclear power breakthrough along the Clinch River, which happens to meander through the U.S. government's largest science and technology campus, Oak Ridge, on its path from the Appalachian Mountains to the Tennessee River.

In the 1970s, the U.S. government and private industry partners sought to build the nation's first commercial-scale "fast breeder" reactor here, an effort abandoned amid concerns about costs and safety. Today, nuclear energy's future still hinges on the same two issues, and advocates argue that SMRs provide the best hope of delivering new nuclear plants that are both affordable and protective of people and the environment. And even amid Washington, D.C.'s budget angst, there was bipartisan support for a new five-year $452 million U.S. government program to spur the technology.
