REQUEST FOR ADDITIONAL INFORMATION REGARDING TECHNICAL SPECIFICATION CHANGES TO REVISE REACTOR COOLANT LEAKAGE DETECTION INSTRUMENTATION ENTERGY NUCLEAR OPERATIONS, INC.

PILGRIM NUCLEAR POWER STATION DOCKET NO. 50-293 By letter dated June 2, 2005, Entergy Nuclear Operations, Inc. submitted an amendment request to revise the Pilgrim Nuclear Power Station (Pilgrim) reactor coolant leakage detection system instrumentation requirements.

The Nuclear Regulatory Commission staff has been reviewing the submittal and has determined that additional information is needed to complete its review.

Pilgrim Leakage Detection Instrumentation Requirements & Actions

1. The proposed Pilgrim Technical Specification (TS) changes to the reactor coolant system (RCS) leakage detection instrumentation would remove the operability requirements of the drywell equipment drain sump from TS 3.6.C.2.a.1 and TS 3.6.C.2.b.1. Please explain how the total leakage limits as specified in TS 3.6.C.1.a.3 would be verified during plant operation.
2. The proposed revised Pilgrim TSs allow for an outage time of 30 days for the drywell floor drain sump. Please explain how TS 4.6.C.1 would verify the requirements of TS 3.6.C.1.a while the drywell floor drain sump is inoperable.

RCS Proposed Leakage Actions The NRC Standard Technical Specifications (STS) Surveillance Requirement (SR) 3.4.4.1 states the following, "Verify RCS unidentified and total LEAKAGE and unidentified LEAKAGE increase are within limits [every 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />s]." The proposed Pilgrim SR 4.6.C.1 consists of the following statement, "Demonstrate drywell leakage is within the limits specified in 3.6.C.1 at least once every 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />." It is not clear to the staff that the proposed Pilgrim SR is consistent with the STS.

1. Provide clarification on how the proposed Pilgrim SR 4.6.C.1 is equivalent to STS SR 3.4.4.1.
2. With the dry well sump monitoring system inoperable, how can you demonstrate that total leakage and the unidentified leakage increase are within the TS specified limits?
