Dear Mr. Heflin:

On June 24, 2014, members of the U.S. Nuclear Regulatory Commission (NRC) staff met with representatives of the Wolf Creek Nuclear Operating Corporation (WCNOC) at the New Strawn Community Center in New Strawn, Kansas.

During the meeting, the participants discussed the NRCs assessment of the WCNOC performance during 2013. Specifically, the NRC staff provided an overview of our inspection activities, findings, and overall performance assessment for the station. Copies of the NRC and WCNOC presentations from the meeting are included as Enclosures 1 and 2, respectively.

During the question and answer session at the end of the meeting, there were no questions.

In accordance with 10 CFR 2.390 of the NRCs Rules of Practice, a copy of this letter will be made available electronically for public inspection in the NRC Public Document Room or from the NRC's Agencywide Documents Access and Management System (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html.

Should you have any questions concerning this matter, we will be pleased to discuss them with you.

Sincerely,

/RA/
