The U.S. Nuclear Regulatory Commission (NRC) said it would increase its oversight of the two-unit Millstone nuclear power plant in Connecticut.
NRC inspectors first identified the unspecified safety-related violation following a security baseline inspection at the plant that ended on Nov. 24, 2014. The finding was documented in an inspection report issued on Jan. 5. The NRC requested plant operator Dominion (NYSE: D) to attend a regulatory conference in February with staff to provide additional information regarding the finding. After looking over the information, NRC determined the finding was appropriately characterized as “greater than green.” A green assessment is for an event of very low safety or security significance.
Millstone 3 was already under additional NRC oversight after receiving a white (low to moderate significance) inspection finding in 2014 stemming from problems that affected the plant’s turbine-driven auxiliary feedwater pump from May 2013 through February 2014.
