Title | Licensee-Identified Violation |
Description | Technical Specification 5.4.1.a requires written procedures to be established, implemented, and maintained covering the activities specified in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Regulatory Guide 1.33, Appendix A, Item 2.g requires procedures for control of nuclear power plant power operation and process monitoring. Procedure 03-1-01-2, Revision 144, Power Operations, step 2.29 requires a licensed operator to verify and ensure that each step in the control rod movement sheet is performed correctly. Contrary to the above, on August 20, 2010, Grand Gulf Nuclear Station reactor operators selected and moved the wrong control rod during a planned sequence exchange, resulting in an improper rod pattern. This issue was documented in the licensees corrective action program in condition report CR GGN-2010-06225. The finding is of very low safety significance because the mispositioned control rod only impacted the fuel cladding barrier. |
