Finding

Title

Failure to Correct a Condition Adverse to Quality Associated with the Salt Service Water System

Description

The inspectors identified a Green NCV of Title 10 of the Code of Federal Regulations (10 CFR) 50, Appendix B, Criterion XVI, Corrective Action, because Entergy did not ensure that an identified condition adverse to quality related to maintenance work on the salt service water (SSW) pumps was corrected. Specifically, Entergy did not implement a procedure change to require installation of additional anti-rotation pins. This procedure change was specified as a corrective action in an equipment apparent cause evaluation (E-ACE) [condition report (CR)-2015-09189], and addressed the assembly of a pump component relied upon to maintain operability of the SSW system. As immediate corrective action, Entergy captured this issue in their CAP as CR-2016-02401, CR-2016-02446, and CR-2016-02454. Additionally, Entergy implemented the necessary procedure change and ensured additional anti-rotation pins were installed during the most recent rebuilds of the A and B SSW pumps. The finding was more than minor because it was associated with the procedure quality attribute of the Mitigating Systems cornerstone, and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the absence of additional anti-rotation pins contributed to the failure of the spider bearings, which led Entergy to declare the A SSW pump inoperable on November 7, 2015. Absent a procedure change identified as a corrective action for this condition that required installation of additional anti-rotational pins, this vulnerability continued to exist, which could contribute to subsequent spider bearing failure, thereby rendering a SSW pump inoperable. In accordance with IMC 0609.04, Initial Characterization of Findings, and IMC 0609, Appendix A, The Significance Determination Process for Findings At-Power, the inspectors determined that this finding was of very low safety significance (Green) because the performance deficiency was not a design or qualification deficiency, and did not involve an actual loss of a safety function of a single train for greater than its technical specification allowed outage time. The inspectors determined that this finding had a cross-cutting aspect in the area of Problem Identification and Resolution, Resolution, because Entergy failed to ensure that established corrective actions adequately resolved and corrected the identified issues in a manner commensurate with their safety significance. Specifically, Entergy did not ensure that the corrective action taken adequately captured the intent of the corrective action as prescribed in the E-ACE. Furthermore, four CR closeout barriers within Entergys CAP failed to recognize and correct the issue.
