Dear Mr. Sunseri:

By letter dated November 4, 2010 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML103200209), as supplemented by letters dated October 19,2011, and January 31,2012 (ADAMS Accession Nos. ML11312A137 and ML12039A091, respectively), you applied for an amendment to the Wolf Creek Generating Station, Facility Operating License No. NPF-42. The proposed change would have revised the Wolf Creek Generating Station Technical Specification 5.6.5, "Core Operating Limits Report (COLR}."

Specifically, the amendment would replace the existing best estimate large break loss-of coolant accident (LOCA) analysis methodology with a methodology based on the U.S. Nuclear Regulatory Commission (NRC)-approved Westinghouse topical report WCAP-16009-P-A, "Realistic Large Break LOCA Evaluation Methodology Using Automated Statistical Treatment of Uncertainty Method (ASTRUM)," January 2005. Subsequently, by letter dated August 23, 2012 (ADAMS Accession No. ML12248A261), you withdrew the amendment request.

The NRC has filed the enclosed Notice of Withdrawal of Application for Amendment to Facility Operating License with the Office of the Federal Register for publication.
