SUBJECT: BRAIDWOOD GENERATING STATION - REQUEST FOR INFORMATION FOR
NRC COMMERCIAL GRADE DEDICATION INSPECTION: INSPECTION
REPORT 05000456/2023010; 05000457/2023010
Dear David Rhoades:
On August 14, 2023, the U.S. Nuclear Regulatory Commission (NRC) will begin a commercial
grade dedication (CGD) inspection at Braidwood Generating Station. This inspection will be
performed in accordance with NRC Inspection Procedure 71111.21N.03, Commercial Grade
Dedication.
The inspection will evaluate the implementation of Braidwoods process for dedicating
commercial-grade items, as required in applicable portions of Title 10 of the Code of Federal
Regulations (10 CFR) Part 50, Appendix B, Quality Assurance Criteria for Nuclear Power
Plants and Fuel Reprocessing Plants, to ensure reasonable assurance is provided that these
items will perform their intended safety function. Additionally, the inspection will evaluate
implementation of Braidwoods procurement process for safety-related components, as
required in Appendix B.
The inspection may include an onsite information gathering visit by the lead inspector. The
inspection will include 2 weeks onsite and will consist of 3 NRC inspectors (including the lead
inspector) along with one observer. The current inspection schedule is as follows:
Information Gathering Visit: June 12-16, 2023
Preparation week: August 7- August 11, 2023
Onsite weeks: August 14-18, 2023 and August 28-September 1, 2023
The purpose of the information gathering visit would be to meet with knowledgeable
individuals of your staff to become familiar with the process for dedicating commercial-grade
items and the process for procuring safety-related components at Braidwood. This visit would
also allow the lead inspector to meet with procurement engineering and other site individuals
responsible for the inspection to ensure a common understanding of expectations for the
inspection. This visit may include a tour of onsite commercial-grade item dedication facilities,
receipt inspection facilities, storage facilities, and installed plant components associated with
potential inspection samples. During the visit (if performed), the lead inspector will also review
the information provided in the initial information request and may request additional
information needed to support the inspection.April 4, 2023

Experience with previous baseline inspections of similar depth and length has shown that this
type of inspection is extremely 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 for both parties, we have enclosed a request for information needed for the
inspection.
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. Insofar as possible, this information should be provided electronically to the lead
inspector. The information request has been divided into four groups:
The first group lists information necessary for our initial inspection scoping activities.
This information should be provided to the lead inspector no later than June 9, 2023.
The lead inspector will communicate the initial selected set of samples no later than
June 30, 2023.
The second group of documents requested are those items needed to support our
in-office preparation activities. This set of documents should be provided to the lead
inspector no later than July 28, 2023. During the in-office preparation activities, the team
may identify additional information needed to support the inspection.
The third group includes the additional information above, a schedule of plant activities
associated with the inspection during the onsite period, and any additional requests
resulting from the potential information gathering visit. This information should be
available to the team onsite on August 14, 2023.
The fourth group includes supporting information to be provided throughout the onsite
inspection. Specifically, corrective action documents and answers to questions
developed during the inspection are requested to be provided as the documents are
generated.
In addition, the enclosure includes information and requests addressing inspection logistics.
The lead inspector for this inspection is Joon S. Park. We understand that our licensing contact
for this inspection is Steve Mitchell of your organization. If there are any questions about the
inspection or the material requested in the enclosure, please contact the lead inspector
at 630-829-9715 or via e-mail at Joon.Park@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.

Withholding.
