“…The input file leverages the NavierStokesFV action. As such it defines all variables, all equations, all initial conditions, and all boundary conditions in approximately 200 lines of inputs [33]. The simulation is initialized using an isothermal flow simulation lasting for approximating 100s of simulation time.…”

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.

“…We demonstrated sibling transfers for the Molten Salt Fast Reactor (MSFR) model [9,10] hosted on the National Reactor Innovation Center Virtual Test Bed [11][12][13]. This model consists of a 2-D RZ coupled multiphysics simulation of a closed-loop MSFR.…”

“…As an example, the velocity field that can be obtained from Pronghorn for the Molten Salt Fast Reactor (MSFR) concept is presented in Figure 3-1. During FY21 and FY22 Pronghorn has been coupled to the neutronics code Griffin to perform multiphysics simulations of the MSRs [73]. During FY22, Pronghorn has been extended with verified capabilities for 2D-3D tracking of species through the reactor core [74].…”
