| Title | Licensee-Identified Violation |
| Description | Title 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, requires, in part, that activities affecting quality be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and be accomplished in accordance with these instructions, procedures, or drawings. Procedure 40OP-9ZZ11, Mode Change Checklist, describes requirements needed to be satisfied prior to changing modes. Contrary to the above on May 2, 2011, the licensee used procedure 40OP-9ZZ11, Mode Change Checklist, to change from Mode 4 to Mode 3, which did not have a requirement to verify the steam generator low pressure set point was operable prior to changing modes. While in Mode 3 operations personnel performed a surveillance test and discovered the steam generator low pressure set point was 905 psia, vice the required 955 psia. This was a condition prohibited by technical specifications and was reported as LER 2011-002-01. The licensee has revised 40OP-9ZZ11, to include verification of steam generator low pressure set point is operable prior to changing modes. This finding was of very low safety-significance (Green) because it is a qualification issue confirmed not to result in an actual loss of function and has been entered into the licensees corrective action program as PVAR 3729932. |
