| Title | Licensee-Identified Violation |
| Description | TS 5.4.1.a commits the licensee to comply with the guidance in Regulatory Guide 1.33, Quality Assurance Program Requirements (Operation), Revision 2. Regulatory Guide 1.33, Appendix A, Paragraph 9a, requires that maintenance that can affect the performance of safety-related equipment should be properly preplanned and performed in accordance with written procedures appropriate to the circumstances. Contrary to this standard, during Refueling Outage RE24 maintenance was performed on primary containment isolation system (PCIS) Relays PCIS-REL-59 and PCIS-REL-60 using WOs 4541159 and 4541160, which contained insufficient guidance and therefore were not appropriate to the circumstances. These WOs did not specify the PCIS function of the relays, nor did it specify a post-work test to ensure that this essential function was tested after maintenance. The inspectors determined that this issue was of very low safety significance since both relays passed their post-work tests on May 8, 2008, and no loss of system safety function resulted from the performance deficiency |
