SUBJECT:

CALLAWAY PLANT - 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

(05000483/2017008) AND REQUEST FOR INFORMATION

Dear Mr. Diya:

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 Callaway Plant

from August 28 - September 1, 2017. The inspection will consist of three reactor inspectors

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

Plant 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 August 11, 2017.

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 Elizabeth Ptasznik 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

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

enclosure will be available electronically for public inspection in the NRC Public Document

Room or from the Publicly Available Records (PARS) component of NRCs document system

(ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-
