| Title | Licensee-Identified Violation |
| Description | TS 5.4.1(a) requires that written procedures recommended by Appendix A of Regulatory Guide (RG) 1.33, Revision 2, be established, implemented, and maintained by the licensee. Section 1.c of RG 1.33, Appendix A, specifies the requirement for procedures that control equipment clearance and safety tagging, and the licensee implements this requirement with procedure OP-AA-109-101, Clearance and Tagging. On 2/6/2008, contractor pipe fitters incorrectly replaced scram solenoid pilot valve (SSPV) 1C11-D5031-116, which was not covered under an appropriate equipment clearance order specifically intended for that work, contrary to the requirements contained in OP-AA-109-101. The objective of the Initiating Events Cornerstone of Reactor Safety is to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. In accordance with NRC IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening, the inspectors determined that the violation was of more than minor significance in that it had a direct impact on this cornerstone objective, one of the key attributes of which is equipment configuration control. The violation was further determined to be of very low safety significance because at the time of the event the entire air system to the Unit 1 Scram Solenoid Pilot Valves (SSPVs) was isolated and depressurized for other refueling outage work activities. The licensee had entered this issue into their CAP as IR 734029. Corrective actions by the licensee included a CAP human performance investigation and an extent-of-condition review of all SSPVs that had been worked by contract pipe fitters to ensure the work had been correctly performed. No additional discrepancies were identified |
