Title | LICENSEE-IDENTIFIED Violation |
Description | Technical Specification 5.4.1.a requires, in part, that written procedures be established, implemented, and maintained as recommended in Regulatory Guide 1.33, Revision 2, Appendix A, dated February 1978. Paragraph 9.a of Regulatory Guide 1.33, Appendix A, requires that maintenance that can affect the performance of safety-related equipment should be properly preplanned and performed in accordance with written procedures, documented instructions, or drawings appropriate to the circumstances. Contrary to the above, on February 19, 2013, maintenance was performed on the motor control center for high pressure core spray pump HPCS-P-2 under Work Order 02025234, but was not completed in accordance with written instructions. Specifically, Step 4.2 was not completed which required re-terminating and torqueing of the C phase electrical connection. This issue was entered into the corrective action program as Action Request AR 289636. A senior reactor analyst performed a detailed risk evaluation for this finding. The finding was of very low safety significance (Green) because the bounding change to the core damage frequency was less than 1.0 x 10-7/year. |
