Junk Plant Seabrook: How Is This Plant Still Operating With This stupidity

IR 05000443/2016007; 8/1/2016 - 9/1/2016; Seabrook Station, Unit 1; Component Design Bases Inspection
• Green.  The team identified a finding of very low safety significance, involving a non-cited violation of Title 10 of the Code of Federal Regulations, Part 50, Appendix B, Criterion XVI, “Corrective Action,” for not performing corrective actions to preclude repetition of a significant condition adverse to quality.  Specifically, in 2008, two of four primary component cooling water (PCCW) pump motors failed within a four month period due to a manufacturing defect.  NextEra established but did not perform a corrective action to replace all four motors with re-wound motors, free of the identified manufacturing defect.  Subsequently, in 2015, a third motor failure occurred due to the same manufacturing defect.  NextEra’s immediate corrective actions included entering this issue into their corrective action program (AR 2153536), implementing an electrical testing program that would provide an early indication of further degradation of the manufacturing defect until motor replacement, and completing a prompt operability determination to assess current PCCW system operability.
