b'Figure 2. Integrated six-year plan for development of metal fuel for both commercial interests and the versatile test reactor (VTR) driver fuel. This plan integrated both separate effects testing in the Oakridge MiniFuel and the Nuclear Science User Facility (NSUF) Disc Irradiation for Separate Effects Testing with Control of Temperature (DISECT) experiments along with the semi-integral testing of FAST and transient conditions in TREAT.Figure 4. Three different thermal analyses of the uranium carbide FAST experiments used to determine the necessary enrichments and power generation rates needed to achieve the desired temperatures. The UC experiments will push FAST to much higher cladding and capsule temperatures than previously explored with the metal fuel, opening it up to support other very high temperature applications.Figure 3. A thermal analysis model of uranium carbide kernel compacts to be used in a FAST experiment in support of General Atomics EM 2 reactor concept. The analysis was used to determine how kernel size may affect the bulk behavior of the compact as it is scaled down for FAST dimensions.2020|AFC ACCOMPLISHMENTS 129'
