| Title | Licensee-Identified Violation |
| Description | Unit 1 Technical Specification 5.4.1.a requires, in part, that Written procedures shall be established, implemented, and maintained covering the following activities...the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Regulatory Guide 1.33, Revision 2, Appendix A, Section 2 specifies written procedures for the safety-related activity of refueling and core alterations. Contrary to the above, the licensee failed to provide adequate procedures for refueling and core alterations during 1R23 Unit 1 refueling outage. Specifically, the licensee over rotated a control rod drive lead screw during reactor disassembly and resulted in having to replace the control rod drive mechanism. Using Manual Chapter 0609, Appendix G, Attachment 1, Checklist 4, PWR Refueling Operation: RCS Level >23, the finding was determined to have very low safety significance (Green) because the finding did not adversely affect: 1) core heat removal, 2) inventory control, 3) electrical power, 4) containment control, or 5) reactivity control. This issue was entered into the corrective action program as Condition Report CR-ANO-1-2011-1921. |
