Research priorities have been determined by the Electric Power Research Institutes (EPRI) Collab-orative Research on Advanced Fuel Technologies working group. These priorities are focused on facilitating material model development, code validation, and licensing of industry safety cases. This prioritization has been documented in a consensus loss-of-coolant accident (LOCA) test plan. Both the test plan and the NRC RIL underscore the need for detailed, in-situ capabilities to rapidly address existing data gaps. These needs encompass detailed temperature Figure 1.
