In the Reference 1 letter, PSEG Nuclear LLC (PSEG) submitted a license amendment request for Salem Nuclear Generating Station (Salem), Unit Nos. 1 and 2. The proposed amendment would revise Technical Specification (TS) 3/4.7.1 0, "Chilled Water System-Auxiliary Building Subsystem," to allow (1) a reduction in the number of required components (two vs. three required chillers) and (2) use of the cross-tie capability between Unit 1 and Unit 2. A supporting change would also be made to the Control Room Emergency Air Conditioning System TS

3. 7.6.1 (Unit 1) and TS 3. 7.6 (Unit 2).

PSEG is issuing this letter to correct two typographical errors in the TS mark ups provided in the Reference 2 letter: 1) correct the numbering of the applicability associated with the LCO 3. 7.1 Oa configuration, and 2) add a period at the end of the# footnote. provides the revised TS mark ups.

PSEG has determined that the information provided in this submittal does not alter the conclusions reached in the 10 CFR 50.92 no significant hazards determination previously submitted. In addition, the information provided in this submittal does not affect the bases for
