Whole Core Multiphysics Simulations Enabled Through Pin Resolved Transport

摘要

In this paper, we demonstrated the benefits of whole core pin-resolved neutron transport for coupled multiphysics problems. For CIPS, the pin-resolved coupled neutron transport, thermal-hydraulic and crud chemistry compoents were crucial to solve together to capture the power shift. In molten salt reactors, new complex physics require advanced modeling and simualtion capabilities to understand the behavior over time. Additionally, high fidelity tools reduce methods development time to determine robust and accurate low-fidelity models to solve these reactors which could take several years to develop and demonstrate.
