“…This section discusses the various methods used for solving the thermal fluid fields. We deploy the Pronghorn porous media formulation of the Navier-Stokes equations with a weaklycompressible fluid spatially discretized with the finite volume method [14,15]. This is a low mach formulation that results in a change to the fluid energy equation called "Weakly Compressible"…”

“…Within this section, the gPBR-200 and gFHR models are described in Section 2.1 and Section 2.2, respectively, and the workflows for hot full-power and cold zero-power conditions are presented in Section 2.3. Both models are very similar in that they use a 2-D axisymmetric Griffin [8,20] model for both the neutronics and microscopic depletion to perform an equilibrium core calculation, a 2-D axisymmetric Pronghorn model that utilizes the Navier-Stokes porous media formulation [5,6] for the full-core thermal model, and representative pebble and TRISO models (for each core zone and burnup group) to compute fuel and moderator temperature.…”

“…Neutronics is coupled to coarsemesh thermal fluid flow, also solving the advection of the precursors in the system. The two codes used were Griffin [3] for neutronics and Pronghorn [14] for the fluid and precursors flow.…”
