rmance and its qualification. In particular, fuel cannot be qualified without irradiation data collected over certain time frames. Accordingly, non-LWR applicants may use existing data (e.g., Advanced Gas-Cooled Reactor program data, legacy metal fuel data), to some degree, to support regulatory licensing. Two documents provide additional background on non-LWR DG-1404, Revision 1, Page 24 fuel qualification: (1) NRC guidance in NUREG-2246, “Fuel Qualification for Advanced Reactors,” issued March 2022 (Ref. 39), and (2) an example of a generic fuel qualification topical report and associated safety evaluation applicable to multiple non-LWR designs, “Uranium Oxycarbide (UCO) Tristructural Isotropic (TRISO)-Coated Particle Fuel Performance," issued December 2020 (Ref. 40). The applicant’s discussion of fuel qualification should focus on the role of the fuel in the safety analysis for the reactor and on the adequacy of the plan to provide the basis for fuel performance as credited in the safety analysis. Sufficient information should be available to support findings of the following: (1) The role of the fuel in the safety analysis is adequately described. This can be accomplished by stating how the fuel will perform during (a) normal operation, including the effects of AOOs, and (b) accident conditions. To support these findings, sufficient information should be provided to clearly identify the design limits of the fuel and the fuel contribution in the accident source term. The applicant’s discussion of the design limits and source term should address uncertainty from any limitations on data available, as reflected in the analyses discussed in Chapters 2 and 3 of NEI 21-07, Revision 1. (2) The fuel qualification plan is adequate. The discussion of the fuel qualification plan should consider the proposed analysis methodologies (e.g., fuel performance codes), the use of existing data, and any ongoing testing or plans to use lead test specimens. If the applicant
