| event text = On February 18, 2013 at 0515 hours, with the reactor at 100% core thermal power, a scram discharge volume valve, CV-302-22B was declared inoperable as required by station procedural direction due to an observed degradation in opening stroke time during performance of quarterly surveillance testing of the Scram Discharge Instrument Volume Vent and Drain Valves. This action was taken consistent with NRC IE Bulletin 80-14. | | event text = On February 18, 2013 at 0515 hours, with the reactor at 100% core thermal power, a scram discharge volume valve, CV-302-22B was declared inoperable as required by station procedural direction due to an observed degradation in opening stroke time during performance of quarterly surveillance testing of the Scram Discharge Instrument Volume Vent and Drain Valves.

Currently, station engineering is evaluating the valve stroke time trend data of CV-302-22B and a plan to address this issue will be developed as part of the Corrective Action Program. Pilgrim Technical Specification 3.3.G applies due to the inoperability of CV-302-22B. | Currently, station engineering is evaluating the valve stroke time trend data of CV-302-22B and a plan to address this issue will be developed as part of the Corrective Action Program.
