SUBJECT: WOLF CREEK GENERATING STATION - NOTIFICATION OF NRC

INSPECTION OF THE IMPLEMENTATION OF MITIGATION STRATEGIES

AND SPENT FUEL POOL INSTRUMENTATION ORDERS AND EMERGENCY

PREPAREDNESS COMMUNICATION/ STAFFING/MULTI-UNIT DOSE

ASSESSMENT PLANS (05000482/2018008) AND REQUEST FOR

INFORMATION

Dear Mr. Heflin:

The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)

staff will conduct a mitigation strategies for beyond-design-basis external events, spent fuel pool

instrumentation, and emergency preparedness enhancements inspection at the Wolf Creek

Generating Station, from January 22 - 26, 2018. The inspection will consist of three reactor

inspectors from the NRCs Region IV office, plus one of the assigned Resident Inspectors at the

Wolf Creek Generating Station for one week. The inspection will be conducted in accordance

with the NRCs Temporary Instruction 2515/191, Inspection of the Implementation of Mitigating

Strategies and Spent Fuel Pool Instrumentation Orders, and Emergency Preparedness

Communication/Staffing/Multi-Unit Dose Assessment Plans.

Experience has shown that this inspection is resource intensive both for the NRC inspectors

and licensee staff. In order to minimize the impact to your onsite resources and to ensure a

productive inspection, we have enclosed a request for documents needed for this inspection

activity. Please note that the documents are requested to be provided by January 5, 2018.

During the onsite inspection, inspectors will verify that plans for complying with NRC Orders

EA-12-049 and EA-12-051 are in place and are being implemented. Inspectors will also verify

the establishment of staffing and communications plans provided in response to the

March 12, 2012, request for information letter, and multi-unit dose assessment information

provided per COMSECY-13-0010, Schedule and Plans for Tier 2 Order on Emergency

Preparedness for Japan Lessons Learned, dated March 27, 2013. These plans and information

were provided in the site specific submittals, which were subsequently reviewed by the NRC

staff for understanding and documented in the NRCs plant safety evaluations (SEs) and safety

assessments. Therefore, appropriate personnel knowledgeable of the stations FLEX

strategies, spent fuel pool instrumentation, and emergency preparedness enhancements should

be available to support the inspectors at the site during the inspection.

We have discussed the schedule for this inspection activity with your staff and understand that

our regulatory contact for this inspection will be Nicole Good of your licensing organization. If

there are any questions about this inspection or the material requested, please contact the lead

inspector, Ryan D. Alexander, by telephone at (817) 200-1195 or by e-mail at

ryan.alexander@nrc.gov.

This letter does not contain new or amended information collection requirements subject to the

Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information collection

requirements were approved by the Office of Management and Budget, control

number 3150 0011. The NRC may not conduct or sponsor, and a person is not required to

respond to, a request for information or an information collection requirement unless the

requesting document displays a currently valid Office of Management and Budget control

number.

In accordance with 10 CFR 2.390 of the NRCs Rules of Practice, a copy of this letter and its
