SUBJECT:
DRESDEN NUCLEAR POWER STATION, UNITS 2 AND 3 - REQUEST FOR
INFORMATION FOR NRC COMMERCIAL GRADE DEDICATION INSPECTION:
INSPECTION REPORT 05000237/2026010 AND 05000249/2026010
Dear Christopher H. Mudrick:
On March 2, 2026, the U.S. Nuclear Regulatory Commission (NRC) will begin a commercial
grade dedication (CGD) inspection at Dresden Nuclear Power Station, Units 2 and 3. This
inspection will be performed in accordance with NRC Inspection Procedure 71111.21N.03,
The inspection will evaluate the implementation of Dresdens 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 Dresdens procurement process for safety-related components, as required in
Appendix B.
The inspection will include 2 weeks onsite and will consist of 3 NRC inspectors (including the
lead inspector). The current inspection schedule is as follows:
Preparation week:
February 23 - 27, 2026
Onsite weeks:
March 2 - 6, 2026 and March 16 - 20, 2026
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. To minimize the inspection impact on the site and to ensure a productive inspection for
both parties, we have enclosed a request for information.

It is important that all these documents are up-to-date and complete 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 January 5, 2026.
The lead inspector will communicate the initial selected set of samples no later than
January 14, 2026.
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 February 16, 2026. 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 no later than February 23, 2026.
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 Megan Gangewere. We understand that our licensing
contact for this inspection is Tara Noah of your organization. If there are any questions about
the inspection or the material requested in the enclosure, please contact the lead inspector via
email at Megan.Gangewere@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.
