Title | Licensee-Identified Violation |
Description | Title 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, states, in part, that activities affecting quality shall be prescribed and accomplished by documented instructions or procedures of a type appropriate to the circumstances. Contrary to this, prior to November 24, 2008, GMP-251, Common Electrical Preventative Maintenance Tasks (QA-1) did not contain documented instructions that were appropriate to the circumstances. Specifically, GMP-251 did not contain procedural guidance for adequately inspecting, cleaning, and lubricating all auxiliary contacts in SR breaker cubicles. On November 24, 2008, the licensee found that the control power fuses were blown on the train B screenhouse exhaust fan and the fan was not running. The licensees investigation found that higher than normal currents caused by the broken auxiliary contacts caused control power fuses to blow. The auxiliary contacts failed from long term wear and a lack of proper lubrication. The inspectors answered No to the MS Cornerstone questions and screened the finding as having very low safety significance (Green) in accordance with IMC 0609, Significance Determination Process, Attachment 0609.04, Phase 1 Initial Screening and Characterization of Findings, Table 4a, dated January 10, 2008. The licensee documented this violation in CR119979. The licensee performed an apparent cause evaluation which determined that GMP-251 was inadequate and implemented corrective actions that included revision of the procedure. |
