Title | Licensee-Identified Violation |
Description | TS 3.6.6, Containment Spray System and Containment Fan Cooler System, requires two containment spray trains and three containment fan cooler trains to be operable in Modes 1, 2, 3, and 4. TS SR 3.6.6.3 verifies that each containment FCU cooling water flow rate is equal to or greater than 1400 gpm every 92 days. Contrary to TS SR 3.6.6.3, during an essential SW header flow balance test in accordance with 3-PT-R200 on March 3, 2015, three of the five FCUs had coolant water flow less than the required 1400 gpm. Engineering was contacted prior to continuing 3-PT-R200 and directed operations to continue and adjust the FCU throttle valves to obtain FCU outlet SW flow at or greater than 1430 gpm (to account for 30 gpm correction factor for instrument error). On April 9, 2015, during a review of anomalous data identified during 3-PT-R200, Entergy engineering determined that the quarterly surveillance test, 3-PT-Q016, EDG and VC Temperature Valves SWNFCV- 1176 and 1176A and SWN-TCV-1104 and 1105, was not performed with the correct SW system alignment. Entergy identified the cause of the condition was improper implementation of improved TS requirements in 2001. Entergy entered this issue into their CAP as CR-IP3-2015-1063 and CR-IP3-2015-2448. The inspectors evaluated this finding using IMC 0609.04, Initial Characterization of Findings, and IMC 0609, Appendix A, Exhibit 3, Barrier Integrity Screening Questions. The inspectors determined that the finding was of very low safety significance (Green) because the finding did not represent a loss of safety function. |
