XE-100 LICENSING TOPICAL REPORT XE00-R-R1ZZ-RDZZ-L, RISK-INFORMED PERFORMANCE-BASED LICENSING BASIS DEVELOPMENT, REVISION 2 (EPID L-2021-TOP-0019)
Dear Travis Chapman:
By letter dated July 7, 2021, (Agencywide Documents Access and Management System (ADAMS) Accession No. ML21196A069), X Energy, LLC (X-energy) submitted its Xe-100 Licensing Topical Report (TR) XE00-R-R1ZZ-RDZZ-L, Risk-Informed Performance-Based Licensing Basis Development, Revision 1 dated June 25, 2021, for the U.S. Nuclear Regulatory Commission (NRC) staffs review. This TR provides a description of the approach taken by X-energy to develop a technology-inclusive, risk-informed, and performance-based process for the selection of licensing basis events (LBEs), safety classification of structures, systems, and components (SSCs) to include associated risk-informed special treatments, and a determination of defense-in-depth (DID) adequacy that will form a portion of the Xe-100 licensing basis. As part of its review, the NRC staff developed a set of preliminary questions to X-energy on November 5, 2021 (ADAMS Accession No. ML21312A166). On November 17, 2021, the NRC staff held a public meeting with X-energy representatives to discuss these questions (ADAMS Accession No. ML21347A947). Subsequently, on March 15, 2022, X-energy submitted Revision 2 of its TR to the NRC staff, addressing the set of preliminary questions (ADAMS Accession No. ML22074A288).
Enclosed is a copy of the NRC staffs draft safety evaluation (SE) for Risk-Informed Performance-Based Licensing Basis Development, Revision 2.
Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) Section 2.390, Public inspections, exemptions, requests for withholding, the NRC staff is providing the enclosed draft SE for X-energy to identify any proprietary information within the draft SE.

Please provide comments on any proprietary aspects of the draft SE within 20 working days from the date of this letter. If the SE includes proprietary information, there will be both proprietary and non-proprietary versions of the SE, and the non-proprietary version will be made publicly available.
