SUBJECT:
CALLAWAY PLANT - NOTIFICATION OF COMPREHENSIVE ENGINEERING
TEAM INSPECTION (05000483/2023011) AND REQUEST FOR INFORMATION
Dear Mr. Diya:
The purpose of this letter is to notify you that U.S. Nuclear Regulatory Commission (NRC) staff
will conduct the comprehensive engineering team inspection at the Callaway Plant beginning on
May 8, 2023. The inspection team will be composed of seven personnel from the NRC Region
IV office. The inspection will be conducted in accordance with NRC inspection procedure (IP)
71111.21M, Comprehensive Engineering Team Inspection, dated October 7, 2022.
The objectives of the inspection are to verify: that risk-significant structures, systems, and
components (SSCs) classified as regulatory treatment of non-safety systems (RTNSS) that are
of high or intermediate importance have been maintained and will operate within their design
and licensing bases requirements; that modifications to risk-significant SSCs did not introduce
conditions that adversely impact the ability of SSCs to perform their design and licensing bases
functions; that the design basis, licensing basis, and performance capability of SSCs have not
been adversely impacted by changes introduced through degraded conditions and other
activities; and that requirements of Title 10 of the Code of Federal Regulations (10 CFR) 50.59
have been appropriately implemented.
The inspection will include an onsite information gathering visit by the team lead and two weeks
of onsite inspection by the team. The schedule for the inspection is as follows:
Onsite Information Gathering Visit: March 20 - 24, 2023
Offsite Preparation Week: May 1 - 5, 2023
Onsite Inspection Weeks: May 8 - 12, 2023, and May 22 - 26, 2023
The purpose of the information gathering visit is to meet with your staff to become familiar with
Callaway Plants SSCs, programs, processes, and procedures and to ensure the resources
needed to support the team, as necessary, to conduct an effective and efficient inspection. This
visit may include a tour of installed plant SSCs associated with potential inspection samples.
During the visit, the team lead will also review the information provided in the initial information
request to select a list of potential inspection samples. The team lead may also identify other
information needed to support the inspection during this visit.

To minimize the impact on your staff and to ensure an effective and efficient inspection, we
have enclosed two separate requests for information needed prior to the onsite information
gathering visit and offsite inspection preparation week. The first request (Enclosure 1) is
generally for information that will be used to choose the inspection samples or information that
will be applicable to all inspection samples throughout the inspection. This information should be
made available to the team lead prior to the information gathering visit. The second request
(Enclosure 2) is for information that is specific to an individual sample and should be made
available prior to the offsite preparation week.
Additional information requests, interviews with your staff, and/or tours of facilities or installed
plant components will be made by the team throughout the inspection to complete their review
of the selected inspection samples. It is important that all documentation provided to the team is
complete and up to date to minimize the number of additional documents requested during the
preparation and/or the onsite portions of the inspection. Additionally, to facilitate an efficient
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.
We understand that Thomas Forland from your Regulatory Affairs organization is our contact for
this inspection. If there are any questions about the inspection or the information requested,
please contact the team lead, Jonathan Braisted, by telephone at 817-200-1469 or by e-mail at
Jonathan.Braisted@nrc.gov. Enclosure 3 contains additional contact information for the
inspection team.
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, under 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 rules and practices, a copy of this letter and its
enclosures 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.
Sincerely,
Vincent G. Gaddy, Chief
Engineering Branch 1

Documents Requested Prior to Information Gathering Visit
The documents and information requested below should generally be made available to the
inspection team for the team's use both on-site and off-site during the information gathering
visit. Electronic format is the preferred media. If electronic media is made available via an
internet based remote document management system, then the remote document access must
allow inspectors to download, save, and print the documents in the NRC's regional office.
Electronic media on compact disc or paper records (hard copy) are acceptable. At the end of
the inspection, the documents in the team's possession will not be retained.
This document request is based on typical documents that a generic plant might have. As such,
this document request is not meant to imply that any specific plant is required to have all of the
listed documents. In addition, your plant specific document titles may vary from the document
titles listed below. We also request that the information provided be sorted by the list below.
Documents requested by March 13, 2023:
1.
Copy of Callaway Plants probabilistic risk assessment (PRA) summary document for
the current internal events, external events (e.g., fire, flooding, seismic), and
shutdown PRA models of record.
2.
From the internal events PRA, a sortable list of structures, systems, and components
(SSCs) sorted by risk achievement worth (RAW) and Birnbaum value for both core
damage frequency (CDF) and large early release frequency (LERF). Include all basic
events with RAW values of 1.3 or greater and Birnbaum values of 1E-6 or greater.
3.
From the external events PRA, a sortable list of SSCs sorted by RAW and Birnbaum
value for both CDF and LERF. Include all basic events with RAW values of 1.3 or
