N2 - Multiphysics interactions between radiation transport and thermal-fluids play an important role in fission reactor design. Progress and challenges in Monte Carlo-based multiphysics modeling are reviewed, with emphasis on software design, data transfers, and iterative solution. This paper then introduces Cardinal, an innovative approach to high-fidelity multiphysics and multiscale analysis using OpenMC, NekRS, and MOOSE. Recent accomplishments in advanced reactor modeling and simulation are presented for a variety of advanced fission concepts, including pebble bed reactors, prismatic gas reactors, molten salt reactors, sodium fast reactors, and systems-CFD coupling. The paper then closes with a discussion on future research directions and current needs in the high-fidelity multiphysics space.
