UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 January 12, 2016 Mr. Kelvin Henderson Site Vice President Catawba Nuclear Station Duke Energy Carolinas, LLC 4800 Concord Road York, SC 29745

SUBJECT:

CATAWBA NUCLEAR STATION, UNITS 1AND2, ISSUANCE OF AMENDMENTS REGARDING NON-CONSERVATIVE TECHNICAL SPECIFICATION ALLOWABLE VALUE (CAC NOS. MF5293 AND MF5294)

Dear Mr. Henderson:

By letter dated December 18, 2015 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML15320A333), the Nuclear Regulatory Commission issued Amendment No. 277 to Renewed Facility Operating License NPF-35 and Amendment No. 273 to Renewed Facility Operating License NPF-52 for the Catawba Nuclear Station, Units 1 and 2, respectively. The amendments revised the Technical Specifications (TSs) to correct non-conservative setpoints. Specifically, the Allowable Value and Nominal Trip Setpoint for the Auxiliary Feedwater Loss of Offsite Power (Function 6.d) was modified. Additionally, the values in the associated Surveillance Requirement 3.3.5.2 were modified to the same values. As part of the change, the amendment also added the applicable footnotes in accordance with TSTF-493, Revision 4, "Clarify Application of Setpoint Methodology for LSSS Functions."

Subsequent to issuance, your staff identified that the amendment numbers were inadvertently omitted from one of the issued pages. Specifically, TS Page 3.3.5-2 did not include the amendment numbers 277 and 273 listed on the page. Accordingly, I have enclosed TS Page 3.3.5-2 with the amendment numbers included.

A copy of the related Safety Evaluation is also enclosed. A Notice of Issuance will be included in the Commission's biweekly Federal Register notice.

K. Henderson If you have any questions, please call me at 301-415-2481.
