| Title | Licensee-Identified Violation |
| Description | TS 3.4, 10.3, Overpressure Protection Systems, states, in part, that in mode 5 or 6, two pressurizer overprotection system relief valves with a lift setting of less than or equal to 375 psig, be operable. With one pressurizer overprotection system relief valve inoperable, action is required to restore the valve to operable status in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or complete depressurization and vent of the RCS. Contrary to the above, on April 11, 2011, PSEG determined that the 2PR1, one of the pressurized overprotection system relief valves, had been inoperable for more than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Upon discovery, PSEG completed depressurization and venting of the RCS. This violation was determined to be of very low safety significance (green) because it did not increase the likelihood of a loss of RCS inventory, it did not degrade PSEGs ability to remove decay heat using the RHR of AFW systems, and did not affect PSEGs ability to terminate a leak path. PSEG entered this violation in their CAP as notification 20504682. |
