Summary
👤
Senior🎓
Top SchoolJames Tompkins is a senior fuel performance modeling engineer with 11 years of experience specializing in nuclear fuel design, qualification, and multiphysics simulation across startups and national labs. He has led fuel development and licensing deliverables for large projects such as X-energy’s Project Long Mott and overseen irradiation campaigns in collaboration with Idaho and Oak Ridge National Laboratories. James developed novel coupled BISON-RELAP-7 models to simulate reactivity insertion accidents and verified moving-interface XFEM capabilities in the MOOSE framework, contributing to international benchmarking efforts. His background spans hands-on reactor operation and experimental validation from his TRIGA work to advanced modeling of TRISO and metallic fuels, bridging experiment, code development, and regulatory documentation. Notably, he was the first to assemble a fully coupled RIA model that captured two-phase flow recovery in a PWR context, reflecting a rare combination of practical reactor experience and open-source multiphysics development. Located in Idaho Falls, he continues to drive fuel qualification and manufacturing modeling for emerging reactor technologies.
