Steedman, MO 65077
SUBJECT:
CALLAWAY PLANT, UNIT 1 - NOTIFICATION OF NRC DESIGN BASES
ASSURANCE INSPECTION (PROGRAMS) (05000483/2019011) AND INITIAL
REQUEST FOR INFORMATION
Dear Mr. Diya:
On October 8, 2019, the NRC will begin an inspection at the Callaway Plant, Unit 1. A three-
person team will perform this inspection using NRC Inspection Procedure 71111.21N, Design
Bases Inspection (Programs); Attachment 1, Environmental Qualification under 10 CFR 50.49
Programs, Processes, and Procedures.
This inspection will evaluate the implementation of the environmental qualification of electrical
equipment program, as required by the Callaway Plant Operating License. Additionally, the
team will perform an inspection of the equipment qualification documentation files to verify that
electrical equipment important to safety meets the requirements of 10 CFR 50.49. The team will
select components that will be subjected to harsh environments and required to mitigate the
consequences of a design basis accident.
The inspection will include an information gathering site visit by the team leader and 2 weeks of
onsite inspection by the team. The inspection will consist of three NRC inspectors. The current
inspection schedule is as follows:
Onsite Information Gathering Visit: October 8, 2019
Preparation Week: October 14-18, 2019
Onsite Weeks: October 21-25, 2019; and November 4-8, 2019
The purpose of the information gathering visit is to meet with members of your staff to become
familiar with the Callaway Plant environmental qualification program. The lead inspector will
request a meeting with your personnel to discuss the site environmental qualification program
and procedures. Additionally, the lead inspector will request a discussion with your staff to
become familiar with the equipment qualification regulations and standards to which the site is
committed. Additional information and documentation needed to support the inspection will be
identified during the inspection, including interviews with engineering managers and engineers.
Our experience with these inspections has shown that they are resource intensive, both for the
NRC inspectors and the licensee staff. In order to minimize the inspection impact on the site
and to ensure a productive inspection, we have enclosed a request for information needed for
the inspection. This information should be made available to the lead inspector during the
F. Diya
2
October 8, 2019 visit. Since the inspection will be concentrated on the environmental
qualification of the equipment, the Equipment Qualification Master List (EQML) should be
available to review during the information gathering visit to assist in our selection of
components.
Additional requests by inspectors will be made during the onsite week for specific documents
needed to complete the review of that component/selection. It is important that all of these
documents are up-to-date and complete in order to minimize the number of additional
documents requested during the preparation and/or the onsite portions of the inspection. To
facilitate the inspection, we request that a contact individual be assigned to each inspector to
ensure information requests, questions, and concerns are addressed in a timely manner.
The lead inspector for this inspection is Gerond A. George. If there are any questions about
the inspection or the requested materials, please contact the lead inspector by telephone at
817-200-1562 or by e-mail at Gerond.George@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 NRC's "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 Publicly Available Records (PARS) component of NRCs document system (ADAMS).
ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the
Public Electronic Reading Room).
Sincerely,
/RA/

Information Requested for Information Gathering Visit (October 8, 2019)
The following information should be provided to the lead inspector in hard copy or
electronic format (electronic database preferred), to the attention of Gerond A.
George by October 8, 2019, to facilitate the reduction in the items to be selected for a
final list of components. The inspection team will finalize the selected list during the prep
week using the documents requested in this enclosure. The specific items selected from
the lists shall be available and ready for review on the day indicated in this request.
- Please provide requested documentation electronically in pdf files, Excel, or other
searchable formats, if possible. The information should contain descriptive names and
be indexed and hyperlinked to facilitate ease of use. Information in "lists" should contain
enough information to be easily understood by someone who has knowledge of
pressurized water reactor technology. If requested documents are large and only hard
copy formats are available, please inform the inspectors, and provide subject
documentation during the first day of the onsite inspection.
1. List of components that are in Equipment Qualification Master List. If the plant is
approved to categorize structures, systems, and component in accordance with
10 CFR 50.69, please provide the Risk-Informed Safety Category of the component.
2. Listing of the Equipment Qualification Master List components sorted by Birnbaum
risk importance and risk achievement worth.
