| Title | Licensee-Identified Violation |
| Description | Unit 1 TS 5.4.1.a, required that written procedures recommended in RG 1.33, Revision 2, Appendix A, shall be established, implemented, and maintained. Item 9.a of RG 1.33, Appendix A, stated, in part, that maintenance affecting the performance of safety-related equipment be properly preplanned and performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances. Contrary to the above, on March 16, 2005, the licensee failed to establish an adequate procedure for the performance of maintenance that affected the performance of a piece of safety related equipment. Specifically, the level of detail in work order package WO 2002-013120-030 and procedure MCI-0-073-PMP002 was inadequate to ensure the proper installation of the Unit 1 HPCI booster pump outboard thrust bearings, which directly led to severe bearing damage and would have eventually resulted in failure of the HPCI pump. The licensee initiated PER 408067 to enter this issue into their CAP and performed corrective maintenance to replace the bearings. The finding was determined to be of very low safety significance in accordance with a Phase 3 SDP of IMC 0609 because the licensee identified and repaired the booster pump prior to an actual failure. |
