| Title | Inadequate Corrective Actions Associated with Submerged Saltwater Pump Motor Cables |
| Description | The inspectors identified an NCV of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Actions, because Constellation did not promptly identify and correct a condition adverse to quality associated with submerged saltwater (SW) pump motor safety-related medium voltage cables. As a result, safety-related cables were subjected to a submerged or continuously wetted environment for extended periods. Immediate corrective action included entering this issue into their corrective action program (CAP), conducting an operability determination (00), and placing these cables into Constellation\'s Medium Voltage Cable Program. The finding is more than minor because it is associated with the equipment performance attribute of the Mitigating Systems cornerstone and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, this condition could lead to cable degradation, increased likelihood of cable failure, and subsequent risk associated with the failure of safety-related equipment. The inspectors determined the finding is of very low safety significance because the finding is a design or qualification deficiency confirmed not to result in a loss of operability. The finding has a cross-cutting aspect in the area of problem identification and resolution, operating experience (DE), because Constellation did not fully implement and institutionalized DE to change station processes and procedures associated with submerged cables (P.2.b per IMC 0310). |
