Oak Harbor, OH and Rockville, MD—A meeting held today by teleconference, between U.S. Nuclear Regulatory Commission (NRC) staff at the agency’s headquarters near Washington, D.C. and FirstEnergy Nuclear Operating Company (FENOC) officials from the Lake Erie shoreline atomic reactor in northwest Ohio, revealed that the problem-plagued Davis-Besse plant’s backup diesel generators (EDGs) likely would not work, if called upon to cool the overheating core in an emergency. The reason is the voltage setting has been set too low, for years or even decades. Watchdogs from Beyond Nuclear, Don’t Waste Michigan, Ohio Sierra Club Nuclear-Free Committee, and Union of Concerned Scientists listened in, and members of the public provided comments to NRC.
The voltage, as documented in the plant’s Technical Specifications, has long been set at only 4,031 volts, whereas a minimum of 4,070, or perhaps even 4,088, volts is needed. First in May 2012, and again in April 2015, FENOC has applied to NRC for approval of a License Amendment Request (LAR) to address the still unresolved problem.
