Profile bio

About James B. Tompkins

Engineer with expertise in fuel performance, multiphysics modeling, and code verification and validation.Master’s Degree research focused on modeling highly anisotropic neutron flux in a unique irradiation position at a 1 MW TRIGA and validating computational results with experiment data he collected. James was a research subcontractor at Idaho National Laboratory for four years where he was the first to assemble a fully coupled model of a reactivity insertion accident (RIA) for a pressurized water reactor (PWR) that first developed and then recovered from two phase flow using BISON and RELAP-7. This model was used to assess performance differences between traditional and accident tolerant fuel concepts during RIAs.Also while at INL, he verified the XFEM implementation in MOOSE for moving material boundary problems, applied material boundary methods to modeling oxidation of cladding in PWR environments, and contributed towards international fuel performance benchmarking efforts with the BISON team.
