Scrutiny of Waterford unit ratcheted up
The Nuclear Regulatory Commission is increasing its oversight of the Waterford Steam Electric Station’s Unit 3 reactor due to a decade-long miscalibration of a radiation monitor.
In a September 13 letter to Entergy Operations, the NRC classified the issue at the Killona, La., facility as a “white finding”—agency parlance for a problem of low to moderate safety significance. (The NRC’s Reactor Oversight Process uses color-coded inspection findings and indicators to measure plant performance, starting at green and increasing to white, yellow, and red, commensurate with the safety significance of the issues involved.)
