UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 April 30, 2014 Mr. Thomas Joyce President and Chief Nuclear Officer PSEG Nuclear LLC P.O. Box 236, N09 Hancocks Bridge, NJ 08038

SUBJECT:

SALEM NUCLEAR GENERATING STATION, UNIT 1 -REQUEST FOR ADDITIONAL INFORMATION REGARDING CORE OPERATING LIMITS REPORT (TAC NO. MF2473)

Dear Mr. Joyce:

By letter dated May 3, 2013 (Agencywide Documents Access and Management System Accession No. ML13129A284), PSEG Nuclear LLC (PSEG) submitted the Core Operating Limits Report (COLR) for Salem Nuclear Generating Station (Salem), Unit 1, Cycle 23.

The U.S. Nuclear Regulatory Commission staff has reviewed the COLR submitted by PSEG and determined that additional information is needed as set forth in the enclosure.

On March 25, 2014, the draft questions were sent to Mr. Paul Duke of your staff, to ensure that the questions were understandable, the regulatory basis for the questions was clear, and to determine if the information was previously docketed. On March 27, 2014, a conference call was held to clarify the questions. Mr. Duke indicated that PSEG will submit a response within 90 days of the date of this letter.

If you have any questions, please contact me at (301) 415-3100 or via e-mail at John.Lamb@nrc.gov.

Request for Additional Information cc w/encl: Distribution via ListServ

REQUEST FOR ADDITIONAL INFORMATION RELATED TO REQUEST FOR CORE OPERATING LIMITS REPORT, CYCLE 23 SALEM NUCLEAR GENERATING STATION, UNIT 1 DOCKET NO. 50-272 By letter dated May 3, 2013 (Agencywide Documents Access and Management System Accession No. ML13129A284), PSEG Nuclear LLC (PSEG) submitted the Core Operating Limits Report (COLR) for Salem Nuclear Generating Station (Salem), Unit 1, Cycle 23. The U.S. Nuclear Regulatory Commission (NRC) staff is reviewing the COLR and has determined that additional information is needed to complete the review.

BACKGROUND Generic Letter (GL) 88-16, "Removal of Cycle-Specific Parameter Limits from Technical Specifications," provides guidance for the preparation of a License Amendment Request (LAR) to modify Technical Specifications (TS) that have cycle-specific parameter limits. An acceptable alternative to specifying the values of cycle-specific parameter limits in TS consists of: (1) the addition of the definition of a named formal report that includes the values of cycle-specific parameter limits that have been established using an NRC-approved methodology and consistent with all applicable limits of the safety analysis, (2) the addition of an administrative reporting requirement to submit the formal report on cycle-specific parameter limits to the Commission for information, and (3) the modification of individual TS to note that cycle-specific parameters shall be maintained within the limits provided in the defined formal report. GL 88-16 further clarifies that in COLR TS [6.x.x] core operating limits shall be established and documented in the COLR, before each reload cycle or any remaining part of a reload cycle.

The analytical methods used to determine the core operating limits shall be those previously reviewed and approved by the NRC.

Based on the GL 88-16 guidance, Salem, Unit 1, TS 6.9.1.9.b lists all approved methodologies to support the cycle-specific core operating parameters specified in TS 6.9.1.9.a. Therefore, both TS 6.9.1.9.a and 6.9.1.9.b in the Salem, Unit 1, COLR TS are associated with the acceptable alternative stated in item (1) above. The current COLR for Salem, Unit 1, Cycle 23, is associated with the acceptable alternative stated in item (2) above. While TS 6.9.1.9.b lists six methodology references, the Salem, Unit 1, Cycle 23, COLR lists 7 references in Section 3.0, "Analytical Methods."

REQUEST FOR ADDITIONAL INFORMATION Please identify which plant and cycle-specific parameters listed in Section 1.0 of the Salem, Unit 1, Cycle 23, COLR are supported by the approved analytical methods listed in Section 3.0 of the COLR.
