Employees at Seabrook Station nuclear power plant failed to detect airborne radiation during a recent full-scale emergency planning exercise, and the failure could lead to a "white" inspection finding and additional inspections, according to the Boston Globe.
The Boston Globe reported that the Nuclear Regulatory Commission has ruled the oversight was of "low to moderate safety significance." Because of the oversight, employees "neglected to communicate information about the release to off-site authorities" — "a performance deficiency that was reasonably within NextEra's ability to foresee and prevent," according to the NRC.
The NRC will reportedly determine within 90 days whether the incident should be finalized as a “white’’ inspection finding, which may be contested by the plant's owners, NextEra Energy. NextEra is currently in the middle of a contentious 20-year license extension for Seabrook Station's 40-year operating license, which expires in 2030.
