| Title | Licensee-Identified Violation |
| Description | The following Severity Level IV violation was identified by the licensee and is a violation of NRC requirements which meet the criteria of the NRC Enforcement Policy, for being dispositioned as a Non-Cited Violation. On October 4, 2014, 1B and 1D Outboard MSIVs leak rate test results were found to b
above allowed limits at 114.7 and 158.7 standard cubic feet per hour (scfh). Technical Specification 3.6.1.3 D, Primary Containment Isolation Valves (PCIVs), requires, in part, that MSIV leakage meet the leak rate limit of 100 scfh to be operable in Modes 1, 2, and 3. Technical Specification 3.6.1.3, Required Action D.1, requires that when MSIV leak rates are not met that they be restored within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> or be in Mode 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and Mode 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. Contrary to the above, since the last successful leak rate test on October 21, 2012, the 1B and 1D Outboard MSIVs became inoperable an action was not taken to restore the leakage rate within limits. The Inboard valves leak rate was sufficiently low to maintain the pathway isolation function. This violation was identified by the licensee and entered in the licensees corrective action program as PER 940890. Traditional enforcement was applicable because no performance deficiency was identified in association with this violation. The licensee had not had sufficient time to perform planned corrective actions developed from previous vendor improvement recommendations. Per the NRC Enforcement Policy section 6.1(d)1 this was determined to be a Severity Level IV violation. |
