ExaSMR: Coupled Monte Carlo Neutronics and Fluid Flow Simulation of Small Modular Reactors

Principal Investigators: Steven Hamilton, lead, Oak Ridge National Laboratory; Paul Romano, Argonne National Laboratory; Kord Smith, Idaho National Laboratory

This project couples high-fidelity neutronics and fluid dynamics in an integrated toolkit for modeling the operational behavior of small modular reactors. It also models the operational behavior of existing light-water reactors at full power with full-core multiphase thermal hydraulics and fuel depletion (over the complete reactor lifetime).
