==Dear Mr. Rhoades :== | |||
The purpose of this letter is to notify you that the U.S. Nuclear Regul atory Commission (NRC) | |||
Region I staff will conduct a Design Bases Assurance Inspection (DBAI) at FitzPatrick Nuclear Power Plan Joe Schoppy, a Senior Reactor Inspector from the NRCs Region I O ffice, will lead the inspection tea The inspection will b e conducted in accordance with Inspection Procedure 71111.21M, Design Bases Assurance Inspection (Team), dated December 8, 2016 (ADAMS Accession No. ML16340B000). | |||
The inspection will evaluate the capability of risk -significant/low-margin components to f unction as designed to support proper system operatio The inspection will also include a review of selected modifications, operating experience, and as applicable, operator action During a telephone conversation on January 3, 2022, with Mr. Ma rk Hawes, FitzPatrick Regulatory Assurance, we confirmed arrangements for an information-gathering site visit and the two-week onsite inspectio The schedule is as follows: | |||
* Information-gathering visit: Week of March 7, 2022 | |||
* Onsite weeks: Weeks of May 2 and Ma y 16, 2022 | |||
The purpose of the information-gathering visit is to meet with members of your staff to identify risk-significant components, modifications, operator actions, and operating experience item Information and documentation needed to sup port the inspection will also be identifie Da v e Werkheiser, a Region I Senior Risk Analyst, will support Joe Schoppy during the inform ation-gathering visit to review probabilistic risk assessment data and identify components to be examined during the inspectio Experience with previous baseline design/modification inspections of similar depth and length has shown this type of inspection is resource intensive, both for the NRC inspectors and the licensee staf In order to minimize the inspection impac t on the site and to ensure a productive D. Rhoades 2 | |||
inspection for both parties, we have enclosed a request for information needed for the inspectio It is important that all of these documents are up-to-date and complete in order to minimize the num ber of additional documents requested during the preparation and/or the onsite portions of the inspectio Insofar as possible, this information should be provided electronically to the lead inspecto The information request has been divided into two groups: | |||
* The first group lists information necessary for our initial inspection scoping activitie This information should be provided to the lead inspector by March 7, 202 By March 14, 2022, the lead inspector will communicate the initial selected set of components and m odification * The second group of documents requested is those items needed to support our in-office preparation activitie This set of documents, specific to the selected components and modifications, should be provided to the lead inspector at the Region I Office no later than April 25, 202 During the in-office preparation activities, the team may identify additional information needed to support the inspection, and those item s will be communicated directly to Mark Hawes. | |||
If there are any questions about the inspection or the material requested in the enclosure, please contact Mr. Joe Schoppy at 610- 337-5286 or via e-mail at jgs@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 3150-001 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 Numbe This letter and its enclosure will be made available for publ ic inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with Title 10 of the Code of Federal Regulations, Part 2.390, Public Inspec tion s, Exemptions, Requests for Withholdin | |||
