A Novel Multiscale and Multiphysics Software Development for LWR Simulation in Support of the Nuclear Renaissance in the UK

A multiscale and multiphysics software development, including a customized coupling environment and improved codes, is necessary to meet the needs of the nuclear community in the UK. This software development incorporates neutron transport, fluid mixing, and solid dynamics methods, and is designed to deliver results at the fuel pin or materials level using relatively few processors. Validation and verification of the multiscale and multiphysics software are being conducted to ensure it becomes state-of-the-art.
