| Title | |
| Description | A self-revealing NCV of very low safety significance of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, was identified because Entergy personnel did not identify and correct a condition adverse to quality related to the HPCI system which caused the system to be inoperable between January 30 and April 28, 2009. Specifically, the balance chamber pressure for the HPCI turbine stop valve, 23 HOV-1, was not set at a value to ensure proper operation of the HPCI turbine system and resulted in a HPCI high steam flow isolation during the performance of the surveillance test. Entergy personnel entered the condition into their corrective action program as CR-JAF-2009-01398. Corrective actions included the performance of a root cause analysis, adjustment of the balance chamber pressure to be higher in the acceptance band consistent with operating experience and increasing the frequency of HPCI surveillance testing. This finding is greater 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 of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). Specifically, Entergy personnel did not take adequate corrective action to establish the balance chamber pressure for 23 HOV-1, following an erratic fast opening of the valve on January 30, 2009. The inspectors determined that the finding was of very low safety significance (Green) using the SDP Phase 3, in accordance with IMC 0609, Appendix A, Determining the Significance of Reactor Inspection Findings for At-Power Situations. The inspectors determined that this finding had a cross-cutting aspect in the area of human performance within the decision-making component because after reviewing the available data and industry operating experience, in January 2009, Entergy personnel incorrectly determined that balance chamber pressure margin was not a contributing cause of the erratic operation of the valve.
