On April 13, 2017, the U.S. Nuclear Regulatory Commission published in the Federal Register (82 FR 17885) its intent to prepare an EIS for the Tennessee Valley Authority’s (TVA) early site permit for the Clinch River Nuclear Site. TVA’s request identified the Clinch River site as suitable for two or more so-called small modular reactors, experimental nuclear power plants which range from 50 megawatts to 300 megawatts, about one-third the power of conventional nuclear power plants.
