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.
