SUBJECT:
MONTICELLO NUCLEAR GENERATING PLANT - REQUEST FOR
INFORMATION FOR NRC COMMERCIAL GRADE DEDICATION INSPECTION:
INSPECTION REPORT 05000263/2023010
Dear Christopher Domingos:
On July 10, 2023, the U.S. Nuclear Regulatory Commission (NRC) will begin a commercial
grade dedication (CGD) inspection at Monticello Nuclear Generating Plant (MNGP). This
inspection will be performed in accordance with NRC Inspection Procedure 71111.21N.03,
The inspection will evaluate the implementation of MNGPs 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 MNGPs 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 three NRC inspectors (including the
lead inspector). The current inspection schedule is as follows:
Preparation weeks:
June 26-30, 2023, and July 3-7, 2023
Onsite weeks:
July 10-14, 2023, and July 24-28, 2023
March 1, 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 May 5, 2023. The lead inspector will
communicate the initial selected set of samples no later than
May 26, 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 June 23, 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 July 10, 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 Atif Shaikh. We understand that our licensing contact for
this inspection is Carrie Seipp of your organization. If there are any questions about the
inspection or the material requested in the enclosure, please contact the lead inspector at
630-829-9824 or via email at Atif.Shaikh@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.
