“…Owe to the numerical challenges associated with the pressure-velocity coupling boundary conditions, a domain overlapping approach for thermal coupling was also studied in this work. It leverages a previous work of the coupled 2D-RZ MSFR primary loop model [23] using Pronghorn and Griffin, also as part of the NEAMS-NRIC Virtual Test Bed exploratory modeling activities in FY21 [24]. This approach is presented in Figure 2-3.…”

The DOE Nuclear Energy Advanced Modeling and Simulation (NEAMS) program supports a full range of computational thermal fluids analysis capabilities and code developments for a broad class of light-water and advanced reactor concepts. The research and development approach under thermal fluids technical area synergistically combines three length and time scales in a hierarchal multi-scale approach. To demonstrate the feasibility and capabilities of a multi-scale thermal fluids capability using these codes, a key joint effort has been pursued to develop an integrated systemand engineering-scale thermal fluids analysis capability with the MOOSE-based codes, through integration of SAM and Pronghorn, both based on the MOOSE framework.
