Conceptual Design of GA-EMS FMR GA-EMS FMR Licensing Strategy Principal Design Criteria Fuel Qualification Plan QA program 2022/Q1 2023/Q1 2022/Q2 NRC hosted a public meeting regarding the FMR PDC on 9/21/2022 Licensing basis event selection and safety analysis Probabilistic risk analysis and process hazard analysis Fuel performance analysis methodology and fuel qualification plans Radionuclide transport methodology Categorization of structures, systems and components into safety-related and non-safety-related systems
4 Accelerated Fuel Qualification (AFQ):
Methodology to Reduce Time and Cost to Qualify New Fuels
- Brings together modeling and simulation with targeted experiments
- Emphasis on physics-based modeling and simulation versus use of empirical fits
- Use of integral as well as separate effects and accelerated experiments K. A. Terrani, N. A. Capps, M. J. Kerr, C.

5 Fast Modular Reactor (FMR) Fuel Test Plan Accelerated testing for long lifetime fuels:
Advanced Test Reactor (ATR) high-burnup irradiation tests Fission accelerated steady-state testing (FAST) approach with irradiation system for high-throughput acquisition (ISHA) capsule to accelerate the irradiation in compact-size rodlets Separate effects test:
Transient Reactor Test (TREAT) facility transient tests Reactivity-initiated accident (RIA) power pulse test in a modified version of the dry in-pile fracture test (DRIFT) capsule Sub-integral test to bound fuel failure criteria:
In-pile tests to component properties Confirm the hermeticity, pellet-cladding mechanical interaction to inform FMR design Fuel Cladding RIA power pulse
