| Title | Quality Standards Not Specified in Design documents that Resulted in Unsupported HPCI Oil Tubing |
| Description | An NRC identified NCV of 10 CFR 50 Appendix B, Criterion III, Design Control, was identified when Entergy did not assure that appropriate quality standards were specified and included in design documents and that deviations from such standards were controlled. Specifically, Entergy did not ensure the oil tubing within the high pressure coolant injection (HPCI) system remained properly supported and routed with an appropriate slope in accordance with design. The issue was entered into Entergys corrective action program as CR-JAF-2008-04040. Corrective actions included establishing work order 172913 to restore the original configuration properly supporting the HPCI tubing lines. This finding is more than minor because it is associated with the design control 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, reliability was affected because the unsupported span of tubing was more susceptible to personnel damage and vibration during HPCI operation, both during surveillance testing and also if called upon to perform its safety function. In addition, the tubing was more susceptible to damage and adverse routing changes during maintenance activities. Therefore, over time, the high pressure fittings associated with the lines would be more likely to suffer failures, retain air bubbles within the lines, and/or leak during pump operation affecting the long-term reliability of the system. This was reasonably within Entergys ability to foresee and prevent because the governing procedures require tube routings, including support locations, be provided during installation of Class I tubing, and a support bracket was available to attach the tubing. The inspectors evaluated the significance of this finding using Phase 1 of IMC 0609, Appendix A, Significance Determination of Reactor Inspection Findings for At-Power Situations, and determined it to be of very low safety significance (Green) because the finding represented a design or qualification deficiency confirmed not to result in loss of operability. The inspectors determined that this finding had a cross-cutting aspect in the area of human performance because the design documents, procedures, and work packages used during the maintenance activities in September and October 2008, were not sufficiently complete to ensure design standards were implemented.
