| Title | Licensee-Identified Violation |
| Description | The following violation of very low safety significance (Green) was identified by the licensee and is a violation of NRC requirements which meets the criteria of the NRC Enforcement Policy for being dispositioned as a non-cited violation. .1 Technical Specification 3.4.1.4.2.b requires that when the reactor is in Mode 5 (cold shutdown) with reactor coolant system loops not filled, each valve or mechanical joint used to isolate unborated water sources shall be secured in the closed position. Contrary to the above, every Unit 2 outage from 2003 through 2010, when the recycle holdup tanks were used to fill the reactor coolant system, boron recovery system valves BR-204 and BR-205 were closed but not secured (locked). The inspectors used Manual Chapter 0609, Appendix G, and determined that the finding was of very low safety significance because there was no reactivity change that warranted a quantitative risk analysis. The licensee entered this violation into the corrective action program as Condition Report 11-7747. |
