SUBJECT:
DRESDEN NUCLEAR POWER PLANT, UNITS 2 AND 3 - NOTIFICATION OF NRC DESIGN BASES ASSURANCE INSPECTION (PROGRAMS) AND INITIAL REQUEST FOR INFORMATION: INSPECTION REPORT 05000237/2022010; 05000249/2022010
Dear Mr. Rhoades:
On March 14, 2022, the U.S. Nuclear Regulatory Commission (NRC) will begin a baseline Design Bases Assurance Inspection (Programs) at Dresden Nuclear Power Station, Unit 2 and Unit 3. This inspection will be performed in accordance with NRC Baseline Inspection Procedure 71111.21N, Design Bases Assurance Inspection (Programs), Attachment 2, Design-Basis Capability of Power-Operated Valves Under 10 CFR 50.55a Requirements.
This inspection will evaluate the reliability, functional capability, and design basis of risk-important power-operated valves (POVs) as required by 10 CFR 50.55a and applicable 10 CFR Part 50, Appendix A and Appendix B, requirements. In conducting this inspection, the team will select risk-important POVs used to prevent and mitigate the consequences of a design basis accident.
The inspection will include two weeks of onsite inspection. The inspection team will consist of three NRC inspectors. The current inspection schedule is as follows:
Preparation week: March 7 - March 11, 2022
Onsite weeks: March 14 - March 18, 2022, and March 28 - April 1, 2022 Experience with previous baseline engineering inspections of similar depth and length has shown 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 three groups:
December 21, 2021 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 31, 2022.
By February 4, 2022, the lead inspector will communicate the initial selected samples and additional information needed to support the in-office preparation activities.
The second group of documents requested is those items needed to support our in-office preparation activities. This set of documents should be provided to the lead inspector no later than March 1, 2022. During the preparation activities, the team may identify additional information needed to support the inspection.
The last group includes the additional information above as well as plant-specific reference material. This information should be available to the team onsite on March 14, 2022. It is also requested that corrective action documents and answers to questions developed during the inspection be provided to the lead inspector as the documents are generated.
In addition, the enclosure includes information and requests addressing inspection logistics.
The lead inspector for this inspection is Jamie Benjamin. If there are any questions about the inspection or the material requested in the enclosure, contact the lead inspector at 630-829-9747 or via e-mail at Jamie.Benjamin@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. This letter and its enclosure will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.
Sincerely, Jamie Benjamin Senior Reactor Inspector Engineering Branch 2 Division of Reactor Safety Docket Nos. 05000237, 05000249 License Nos. DPR-19, DPR-25 Enclosure:
