SUBJECT:

DRESDEN NUCLEAR POWER STATION, UNITS 2 AND 3 - INFORMATION REQUEST FOR AN NRC TRIENNIAL 10 CFR 50.59 (EVALUATION OF CHANGES, TESTS, AND EXPERIMENTS) BASELINE INSPECTION

Dear Mr. Rhoades:

On May 23, 2022, the U.S. Nuclear Regulatory Commission (NRC) will begin a 10 CFR 50.59, (Evaluation of Changes, Tests and Experiments), baseline inspection at the Dresden Nuclear Power Station, Units 2 and 3. This inspection will be performed in accordance with the NRC baseline Inspection Procedure (IP) 71111.17T. The onsite dates for this inspection will be May 23-27, 2022.

Experience has shown that these baseline inspections are 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 documents needed for the inspection. These documents have been divided into two groups.

The first group of information is necessary to ensure that the inspection team is adequately prepared for the inspection. This information should be made available via electronic methods no later than April 11, 2022. The inspection team will review this information and, by April 18, 2022, will request specific items that should be provided for review in the regional office by May 9, 2022.

The second group of requested documents contains additional items that the team will review, or need access to, during the inspection. Certain documents contained within Group II (i.e.,

Item (1)), will be requested for review in the regional office prior to the inspection by May 9, 2022, as identified above. The remaining documents should be available by the first day of the inspection, May 23, 2022.

If there are any questions about the material requested or the inspection in general, please contact Mr. J. Benjamin at 630-829-9747 or Jamie.Benjamin@nrc.gov.March 4, 2022 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 Title 10, Code of Federal Regulations (CFR), Section 2.390 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's 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, Jamie Benjamin Senior Reactor Inspector Engineering Branch 2 Division of Reactor Safety Docket Nos. 05000237, 05000249 License Nos. DPR-19, DPR-25

The inspection team will select specific items from the information requested below and submit a list to your staff by April 18, 2022. We will request that certain items be made available to the inspection team by May 9, 2022. We request that the remaining items selected from the lists be available and ready for review on the first day of inspection.

All requested information should identify the associated system and cover the time frame from the receipt of information for the last 50.59 inspection to the present.

The required information identified below should be provided on compact disc (CD) or uploaded to accessible links (preferred format is a share file type system). If CDs are provided, please provide three copies of each CD submitted (i.e., one for each inspector). The preferred file format is a searchable pdf file. The CDs should be indexed and hyper-linked to facilitate ease of use, if possible. If you have any questions regarding this information, please call the inspection team leader as soon as possible.

(1) List of all 10 CFR 50.59 completed evaluations involving (a) calculations, (b) procedure revisions, (c) changes to the facility (modifications), (d) non-routine operating configurations, or (e) departures in methods of analyses. This list should include 50.59 evaluations for the following:

a. Changes that have been made under the provisions of 10 CFR 50.59 that have been updated in accordance with 10 CFR 50.71(e)(4) since the last MOD/50.59 inspection;

b. Modifications that are field work complete; and

c. Changes to calculations (or initiation of new calculations) that have been issued. The list should contain the number and title of each document, a brief description of the change, and the corresponding number and type of the affected document (i.e., the modification or procedure to which the evaluation applies). The list should NOT include any evaluations in which prior NRC approval was sought and obtained.

(2) A list of all 10 CFR 50.59 changes that have been screened out as not requiring a full evaluation involving: (a) calculations; (b) procedure revisions; (c) changes to the facility (modifications); (d) non-routine operating configurations; or (e) departures in methods of analyses.

The list should contain the number and title of each document, a brief description of the change, and the corresponding number and type of the affected document (i.e., the modification or procedure to which the evaluation applies).

(3) A list of any modifications, procedure revisions, or the Updated Final Safety Analysis Report (UFSAR) changes where it was determined that 10 CFR 50.59 did not apply.

Enclosure (4) A list of calculation changes that have been issued for use.

(5) A list of corrective action documents (open and closed) that address 10 CFR 50.59 issues, concerns, or processes. These documents should also include the associated corrective action documents and the 50.59 change implementation.

The list should contain the number, title and revision (or date) of each document, the affected system and corresponding documentation (if applicable), and should be sorted in order of significance.
