| Title | Inoperability of the Refueling Water Storage Tank Not Recognized as a Safety System Functional Failure |
| Description | The inspectors identified a Green finding for the licensees failure to identify and document Safety System Functional Failures (SSFF) in accordance with REG-NGGC- 0009, NRC Performance Indicators and Monthly Operating Report Data. The licensee did not recognize that rendering the refueling water storage tank inoperable by placing the non-seismically qualified purification system in operation as documented in LER 05000261/2011-001-00, Condition Prohibited by Technical Specifications When Non- Seismic System was Aligned to Refueling Water Storage Tank due to Regulatory Requirements not Adequately Incorporated in Plant Documentation also created a SSFF. The licensee entered the issue into the CAP as NCR 539132. Corrective actions are still being evaluated. The inspectors determined that the licensees failure to identify and document a SSFF was a performance deficiency. Specifically, Attachment 7 of REG-NGGC-009, NRC Performance Indicators and Monthly Operating Report Data, Rev. 11 requires documenting SSFFs. The finding was determined to be more than minor because the minor screening question of whether the performance deficiency would have caused the SSFF PI to exceed a threshold was determined to have occurred. Specifically, had the licensee recognized the SSFFs and documented them during the investigation of LER 05000261/2001-001-00, the SSFF PI would have crossed the green/white threshold in the 4th quarter of 2010. The finding screened as Green because no loss of operability or functionality resulted from the failure to recognize the SSFF and document the event as described in LER 05000261/2011-001-00. The inspectors determined this performance deficiency had a cross-cutting aspect in the Corrective Action Program component of the Problem Identification and Resolution Area, because the licensee did not thoroughly evaluate the condition described in LER 05000261/2011-001-00, to include conditions such as a SSFF. |
