Summary
👤
Senior🎓
Top SchoolWilliam Wieselquist is a nuclear engineering leader with over a decade of experience at Oak Ridge National Laboratory, currently serving as National Technical Director for criticality benchmarking of HALEU fuel cycles and Director of the SCALE code system. He blends deep expertise in radiation transport, reactor physics, depletion methods, and uncertainty propagation with hands-on stewardship of widely used analysis tools like ORIGEN and Sampler. His work spans multilateral DOE/NRC collaborations and practical regulatory support, reflecting both strategic program leadership and detailed methodological development. Trained with a PhD in Nuclear Engineering (math minor) from NC State, he is as comfortable developing spatial discretizations and quasidiffusion methods as he is coordinating multi-lab benchmark efforts that de-risk advanced fuel cycles.
