The Transformational Challenge Reactor (TCR) represents a significant advancement in nuclear reactor technology, taking into consideration modularity, efficiency, and safety. This study explores the coupling between thermal behavior and the coolant gas flow behavior of the TCR’s 3D-printed ceramic core under various operating conditions. Using nitrogen as a coolant, experiments were performed at pressures ranging from 20.4 bar to 40.8 bar (300 to 600 psi) and temperatures from 100°C to 300°C. The main parameters including gas inlet and outlet temperatures, the TCR wall temperature at the inlet and outlet, and flow rates, were analyzed to evaluate heat transfer efficiency and system stability. Results indicate that higher pressures improve thermal conductivity, while increased flow rates improve heat dissipation but reduce residence time. Stable Pressure Vessel (PV) wall temperatures across all conditions confirm effective insulation. These findings validate the TCR’s potential for high-efficiency, high temperature applications, providing a foundation for its deployment in next-generation nuclear systems.
