| On September 21, 2016, members of the U.S. Nuclear Regulatory Commission (NRC) staff met with representatives of Wolf Creek Generating Station to discuss an apparent violation related to preventive maintenance activities for the emergency diesel generator excitation system diodes as documented in NRC Inspection Report 05000482/2016008, issued on August 19, 2016, (ML16235A132). The focus of the regulatory conference was a discussion of information important to characterize the safety significance of the finding associated with the preventative maintenance deficiency and differences between the NRC and Wolf Creek Generating Station's probabilistic risk assessment methodologies used to evaluate the deficiency. In addition, the attendees discussed differences in the characterization of the underlying performance deficiency. The NRC staff asked questions during this regulatory conference, with some questions requiring additional information that you agreed to provide after the conference was completed. The NRC will continue to review the information that you provided during the Regulatory Conference and the subsequent information that was requested in order to reach a final significance determination. We will issue a final significance determination letter to you when that review has been completed. This Category 1 public meeting was attended by four members of the public at the Region IV office, as well as members of the public on the teleconference bridge that was provided. A copy of your presentation slides are included as Enclosure 1. The NRC slides are included as Enclosure 2. | | |

UNITED STATES NUCLEAR REGULATORY COMMISSION REGION IV 1600 E LAMAR BLVD ARLINGTON, TX 76011-4511 September 27, 2016 EA-16-069 Adam C. Heflin, President and Chief Executive Officer Wolf Creek Nuclear Operating Corporation P.O. Box 411 Burlington, KS 66839

SUMMARY
OF REGULATORY CONFERENCE TO DISCUSS SAFETY SIGNIFICANCE OF WOLF CREEK GENERATING STATION EMERGENCY GENERATOR EXCITATION DIODE APPARENT VIOLATION
Dear Mr. Heflin:
On September 21, 2016, members of the U.S. Nuclear Regulatory Commission (NRC) staff met with representatives of Wolf Creek Generating Station to discuss an apparent violation related to preventive maintenance activities for the emergency diesel generator excitation system diodes as documented in NRC Inspection Report 05000482/2016008, issued on August 19, 2016, (ML16235A132). The focus of the regulatory conference was a discussion of information important to characterize the safety significance of the finding associated with the preventative maintenance deficiency and differences between the NRC and Wolf Creek Generating Stations probabilistic risk assessment methodologies used to evaluate the deficiency. In addition, the attendees discussed differences in the characterization of the underlying performance deficiency.
The NRC staff asked questions during this regulatory conference, with some questions requiring additional information that you agreed to provide after the conference was completed. The NRC will continue to review the information that you provided during the Regulatory Conference and the subsequent information that was requested in order to reach a final significance determination. We will issue a final significance determination letter to you when that review has been completed.
This Category 1 public meeting was attended by four members of the public at the Region IV office, as well as members of the public on the teleconference bridge that was provided. A copy of your presentation slides are included as Enclosure 1. The NRC slides are included as .
A. Heflin In accordance with 10 CFR 2.390 of the NRCs Rules of Practice, a copy of this letter and its enclosures will be available electronically for public inspection in the NRCs Public Document Room or from the Publicly Available Records (PARS) component of the NRCs ADAMS.
