NRC CAL – NOV (White)

On August 8, 2011, the NRC issued a White Significance Determination Process finding and Notice of Violation (NOV) for two violations to Dominion Nuclear Connecticut, Inc. as a result of inspections at the Millstone Power Station Unit 2. The finding was based on multiple human performance errors, and the NOV was based on two violations which involved the licensee's failure to meet its Technical Specifications requirements. Together these failures caused and exacerbated the February 12, 2011, unanticipated eight percent reactor power increase during the main turbine control valve testing.
