Abstract

The unique feature of the Transformational Challenge Reactor is the advanced manufacturing. More precisely, selected components, including the fuel and silicon carbide reflector elements, are designed to be manufactured by 3D printing. This unique feature broadens the design of the cooling channels since it is possible to set any arbitrary shape for the coolant (helium) flows. In this study, four different designs of the helium channels of the bottom reflector are proposed and analyzed by Serpent simulations with the goal of maximizing neutronics and fluid-dynamics performances and the manufacturing process. The Serpent Monte Carlo code allows to model a reactor core by hybrid geometry. In the hybrid geometry, the 3D printed components can be modeled by the CAD geometry (using the manufacturing CAD files) and the other components can be modeled by combinatorial geometry.
