((date:long LONG MOTT ENERGY, LLC - PLAN FOR AN AUDIT REGARDING OF PRELIMINARY SAFETY ANALYSIS REPORT CHAPTER 2 AND SECTIONS 3.7, 6.4.1, AND 7.3.1 OF THE PRELIMINARY SAFETY ANALYSIS REPORT FOR THE LONG MOTT GENERATING STATION CONSTRUCTION PERMIT APPLICATION (EPID NO. L-2025-CPS-0000) Applicant: Long Mott Energy, LLC Applicant Address: 530 Gaither Road, Suite 700 Rockville, MD 20850 Plant Name and Units: Long Mott Generating Station (4 units) Docket No.: 50-614
Background:
By letter dated March 31, 2025, (Agencywide Documents Access and Management System (ADAMS) Package Accession No. ML25090A057) Long Mott Energy, LLC (LME), submitted a construction permit (CP) application and corresponding preliminary safety analysis report (PSAR) to the U.S. Nuclear Regulatory Commission (NRC) staff for a reactor facility pursuant to Title 10 of the Code of Federal Regulations (10 CFR), Part 50, Domestic Licensing of Production and Utilization Facilities, and section 103, Commercial Licenses, of the Atomic Energy Act of 1954, as amended. The facility, referred to as Long Mott Generating Station (LMGS), would be built in Calhoun County, Texas. On May 12, 2025 (ML25115A247), the NRC staff accepted LMEs CP application for docketing. A notice of the acceptance for docketing was published in the Federal Register on May 2, 2025 (90 FR 18874). The NRC staff is conducting a detailed review of the LMGS CP application. This regulatory audit is intended to assist the NRC staff in its review of the LMGS CP application.
Purpose:
The purpose of this audit is for the NRC staff to gain a better understanding of the LMGS CP application by providing an opportunity to review and discuss the material used to support statements or conclusions in PSAR Chapter 2 and Sections 3.7, 6.4.1, and 7.3.1. The audit is expected to facilitate a more effective and efficient review by allowing the NRC staff to review and discuss the supporting material with the objective of improving communication and eliminating unnecessary requests for additional information. If the NRC staff identifies information that is needed to support a regulatory finding pertaining to the review of the CP application, LME will need to submit that information on the application docket. Commented [SP1]: Suggested reordering just to make clear these are all sections of the PSAR. Commented [SP2]: I dont think we need this sentence for an audit plan. It is fine to keep the sentence, if youd like, but if so, need to correct the date and FRN citation. (The FRN for acceptance for docketing wasnt published until sometime in June.) Regulatory Audit Basis: The basis for the audit are the regulations in 10 CFR pertinent to the NRC staffs review of the CP application, including 10 CFR 50.34, Contents of applications; technical information, 10 CFR 50.35, Issuance of construction permits, 10 CFR 100.20, Factors to be considered when evaluating sites, 10 CFR 100.21, Non-seismic site criteria, 10 CFR 100.23, Geologic and seismic siting criteria, and Appendix S to Part 50, Earthquake Engineering Criteria for Nuclear Power Plants Regulatory Audit Scope: This audit will focus on information provided by LME onin the electronic reading room (eRR) and during meetings and interactions with LME. This audit will provide the NRC staff with information related to the review of the LMGS CP application, specifically related to Chapter 2, Site Characteristics, Section 3.7, Civil and Structural Analyses, Section 6.4.1, Reactor Building, and Section 7.3.1, Civil Structures. Specific objectives and topics to be discussed will be identified in subsequent correspondence, such as an email, and dates will be proposed for discussion of the information. Information and Other Material Necessary for the Regulatory Audit: LME should be prepared to provide documents, reports, calculations, computer code verification, and other material, as applicable, supporting the analyses documented in the PSAR chapter and sections detailed in the Regulatory Audit Scope. The NRC staff may request that LME make these additional materials available in the eRR or during a site visit, if one is conducted. Information requests and discussion items will be provided separately throughout the audit. Team Assignments: Adrian Muniz Senior (Sr.) Project Manager, Audit Lead Timothy Drzewiecki Sr. Reactor Systems Engineer, Lead Technical Reviewer Denise McGovern Sr. Project Manager, Audit Support Ondra Dukes Project Manager, Audit Support Richard Rivera Project Manager, Audit Support Amitiva Ghosh Physical Scientist - Hazards Analyst Carol Dye Geologist Jason White Physical Scientist - Meteorologist Jenise Thompson Geologist Nebiyu Tiruneh Hydrologist Hosung Ahn Hydrologist Rosalynn Wang Geophysicist Vladimir Graizer Seismologist Ian Jung Sr. Reliability and Risk Analyst Robert Roche-Rivera Sr. Civil Engineer - Structural CNWRA Contractor Support Additional audit team members will be added, as needed. Logistics: Commented [RR3]: @Timothy Drzewiecki and @Robert Roche-Rivera could you review this section and edit as appropriate? I believe that the first 2 references are still applicable, but the last one, not so much. Commented [RR4R3]: I think that 10 CFR 100.23 should apply. Additionally, I added, Appendix S to Part 50Earthquake Engineering Criteria for Nuclear Power Plants. Commented [RR5]: @Timothy Drzewiecki @Robert Roche-Rivera and @Nebiyu Tiruneh, please review the list of staff assigned to this audit, and let me know if any additions/deletions are needed. Note: I am including all of the PMs and the tech lead to make sure that we have proper coverage at all times. Commented [NT6R5]: @Richard Rivera I have included @Hosung Ahn in the list of attendees for the audit. Commented [RR7R5]: Can we add the following CNWRA contractor staff: Kristin Ulmer John Stamatakos May also add: Nilesh Chokshi and Biswajit Dasgupta. Commented [RR8R5]: @Robert Roche-Rivera for the audit plan I will simply add a line indicating contractor support from CNWRA. As we coordinate the audit meetings, we inform LME the names and email addresses of the contractors that will need access to the eRR. Commented [SP9]: Define somewhere (Center for Nuclear Waste Regulatory Analyses, I think) Entrance Meeting: June XX, 2025 Exit Meeting: September 2026; precise date, and time are to be determined. The audit will follow the guidance in the Office of Nuclear Reactor Regulations (NRR) Office Instruction LIC-111, Revision 2, Regulatory Audits, (ML24309A281). Audit meetings will take place mainly in a virtual format, using Microsoft Teams or other similar platform. Audit meetings will be scheduled on an as needed basis and, if applicable, once the NRC staff has had the opportunity to review documents placed in the eRR. If a site visit is needed, review topics will be provided to LME, and mutually agreeable dates will be established. The audit will begin in June 2025, and continue for approximately 16 months, with activities occurring intermittently during that period. Interim status report(s) on topics being addressed by the audit will be provided to LME. The audit period may be reduced or extended, depending on the progress made by the NRC staff and LME in addressing audit questions. Additional audit activities may be planned as necessary to support the NRC staffs understanding of information needed to complete the review of the LMGS CP application. To improve the efficiency of the audit, LME and the NRC staff discussed the use of an eRR, established by LME, that would allow the NRC staff read-only access to the technical information provided by LME. Use of the eRR is acceptable provided that LME establishes measures to limit access to specific NRC staff (e.g., based on NRC email addresses or the use of passwords which will only be assigned to the NRC staff directly involved in the audit on a need-to-know basis), and to make the documents view-only (i.e., prevent the NRC staff from saving, copying, downloading, or printing any documents). The conditions associated with the eRR must be maintained throughout the audit process. The NRC audit project managers will provide LME with the names of the NRC staff audit team that will require access to the eRR. Special Requests: None. Deliverables: The NRC staff will issue an audit summary within 90 days after the exit meeting. The summary will be publicly available in ADAMS. If you have any questions related to this audit, please contact Richard Rivera at 301-415-7190 or via email at Richard.Rivera@nrc.gov. Date: Month XX, 2025 Commented [SP10]: Consider adding (not required) / For the PRA audit plan, we included: The NRC staff requests that LME subject matter experts are available to answer questions during the audit. LME should track the NRC staffs audit questions and make the responses available in the eRR. If any changes, such as PSAR revisions, are identified during the audit, the NRC staff requests LME to share the draft in the eRR for discussion before formal submission.
