| Title | Licensee-Identified Violation |
| Description | TS 3.3.1.1, Reactor Trip System Instrumentation, requires one operable intermediate range instrument in Modes 1, 2, and 3. When that requirement is not met, TS 3.0.3 requires that action be initiated within one hour to place the unit in hot standby within the next six hours. Contrary to the above requirements, on November 24, 2011, after technicians input incorrect trip setpoints that rendered both TS 3.3.1.1 required intermediate range NISs inoperable, PSEG did not initiate action within one hour to place the unit in hot standby within the next six hours. Upon discovery of the inoperable instruments on December 11, 2011, PSEG took immediate corrective action to input the correct intermediate range setpoints and restore operability and entered this issue into the CAP as notification 20538425. The inspectors determined that the finding was of very low safety significance (Green) in accordance with NRC IMC 0609, Attachment 4, Phase 1 - Initial Screening and Characterization of Findings, Mitigating Systems Cornerstone, because the finding did not represent a loss of safety system function, an actual loss of safety function of a single train for greater than its TS allowed outage time, an actual loss of safety function of one or more non-technical specification trains of equipment designated a risk significant per 10 CFR 50.65 for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and did not screen as risk significant due to seismic, flooding or severe weather initiating event. |
