US nuclear reactor performance assessment
S. Himmelstein | April 12, 2022“The work of the nuclear power plant operators for almost every reactor fully meets our stringent safety and security performance objectives,” said Andrea Veil, director of the NRC’s Office of Nuclear Reactor Regulation. “Yet even those high-performing units will undergo thousands of inspection hours this year under our normal ‘baseline’ inspection program.”
Davis-Besse, a 908-MWe pressurized water reactor located in Oak Harbor, Ohio, was also moved to the Regulatory Response category due to a greater-than-green finding, or a finding of more than very low safety significance, identified by NRC personnel during a scheduled cybersecurity inspection. In addition, more recently, the NRC issued Energy Harbor a violation notice involving the failure to select a suitable replacement part for Davis-Besse’s emergency diesel generator speed switch. The speed switch design was not compatible with the station’s 125/250 V DC battery system, according to the agency.
