| Title | Licensee-Identified Violation |
| Description | Title 10 CFR Part 50, Appendix B, Criterion V, requires, in part, that activities affecting quality shall be prescribed by documented instructions or procedures of a type appropriate to the circumstances. Procedures SOP-102 (A and B), Residual Heat Removal System, Revisions 16 and 11, respectively, delineate the steps to operate the residual heat removal system, an activity affecting quality. Contrary to the above, on March 22, 2011, Procedures SOP-102 (A and B) did not delineate actions that would prevent operating both trains of residual heat removal and causing a potential steam voiding condition of the residual heat removal system in Mode 4. The licensee documented the issue in Condition Report CR-2010-006268 and corrected the procedures. A senior reactor analyst performed a bounding risk evaluation and determined the issue was of very low safety significance. This non-cited violation addresses the enforcement aspect of the licensee event report documented in Section 4OA3.3. |
