| Title | Licensee-Identified Violation |
| Description | Technical Specification 5.4.1 requires that written procedures be established and implemented for activities provided in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Procedures specified in Regulatory Guide 1.33 include procedures for performing maintenance. Contrary to this requirement, on August 16, 2008, operations personnel unsuccessfully attempted to pump the Unit 3 drywell floor drain sump to partially satisfy TS Surveillance Requirement 3.4.4.1. The licensee identified later that the valve plug had separated from the stem in the Drywell Floor Drain Sump Containment Isolation Valve 3-2001-1005. The licensee determined that the maintenance procedure governing valve replacement was inadequate which resulted in higher than desired actuator output and seating forces. The inspectors reviewed the licensees corrective actions. The inspectors had no issues with the licensees corrective actions and determined that they were completed or had an acceptable time table for completion. This incident was identified in the licensees corrective action program as Issue Report 807914 and documented in LER 249/2008-001-00, Unit 3 Drywell Floor Drain Sump Monitoring System Declared Inoperable. This violation was determined to be of very low safety significance because the containment isolation valve failed in a closed condition ensuring its ability to perform a containment isolation function |
