Abstract

On April 25, 2004, a review of the control room operator's logs was completed as a result of a discrepancy identified on February 24 between the Salem Units 1 and 2 Technical Specifications (TS) 3.6.3.2 and the current licensing basis analyses assumptions.

Specifically, PSEG identified that TS 3.6.3.2 Action b (for both Salem Units) was non-conservative. TS 3.6.3.2 Action b contains an allowable outage time of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> whenever three or more Containment Fan Coil Units {BK}(CFCU) are inoperable provided that two Containment Spray {BE)(CS) pumps are operable. Current design analyses do not support the plant configuration allowed by TS 3.6.3.2 Action b. The control room operators log review identified at least two occasions (September 3, 2002 and July 3, 2003 for Salem Units 1 and 2 respectively) where T.S. 3.6.3.2 Action b had been entered.

The cause of this event was determined to be the existence of the non-conservative Technical Specification. The reason for failing to identify the condition earlier was determined to be an inadequate review for an Updated Final Safety Analysis Report (UFSAR) change related to NSAL 00-010 'Containment Safeguards Heat Removal Capability.' Corrective actions taken were: (1) In accordance with Administrative Letter 98-10, Salem Operations established guidance to enter Technical Specification 3.0.3 when more than two Containment Fan Coil Units are inoperable regardless of the number of operable Containment Spray pumps until the Technical Specifications are revised, (2) A license change request to correct the Technical Specification was submitted on April 15, 2004, (3) Other similar generic technical correspondence will be reviewed for proper closure and the event will be shared with engineering personnel.

This is being reported under the requirement of 10CFR50.73(a)(2)(v)(C) and (D), as a condition that could have prevented the fulfillment of a safety function of a system needed to remove heat, or control the release of radioactive material, or mitigate the consequences of an accident.

CORRECTIVE ACTIONS

1. In accordance with Administrative Letter 98-10, Salem Operations has established guidance to enter Technical Specification 3.0.3 when more than 2 Containment Fan Coil Units are inoperable regardless of the number of operable Containment Spray pumps. (As committed in LCR S03-07, dated April 15, 2004)

2. A Technical Specification change to TS 3.6.2.3 Action b was submitted on April 15, 2004.

3. This event will be reviewed by the Engineering Training Review Group for inclusion in the Engineering Continuing Training Program.

4. Other generic technical correspondence similar to NSALs will be reviewed for appropriate disposition.

COMMITMENTS

Except as stated in corrective action 1 above, the remaining corrective actions cited in this LER are voluntary enhancements and do not constitute commitments.
