Abstract
The resulting downselected TCR core design has challenging design characteristics, yet it balances simplicity and robustness with safety, licensing, and operation. The core is 1. cooled with pressurized helium, 2. has a thermal-to-intermediate neutron spectrum, 3. contains TRISO-in-SiC fuel forms, 4. contains yttrium hydride in steel moderator forms, 5. uses an external control mechanism, and 6. flows coolant in and out from the bottom of the vessel and once through the core (top down). Potential design changes may be implemented to accommodate changes to desired outcomes or performance metrics.
