Bio
Dr. William Wieselquist is a Distinguished Research and Development Staff member in the Nuclear Energy and Fuel Cycle Division at Oak Ridge National Laboratory (ORNL). Since 2019, he has served as Director of the SCALE Code Suite. He earned his Ph.D. in Nuclear Engineering from North Carolina State University in 2009.
From 2009 to 2012, Dr. Wieselquist was a staff member at the Paul Scherrer Institut, where he led the development of an uncertainty quantification platform for the Studsvik Scandpower core analysis codes. Dr. Wieselquist also contributed to core safety analysis for Switzerland’s Beznau Nuclear Power Plant, Units 1 and 2.
At ORNL, he has taken on key development roles within the SCALE Code Suite. Dr. Wieselquist has served as the lead developer and manager for both the ORIGEN depletion/decay code and the Sampler code for sampling-based uncertainty quantification and has also contributed to the development of the Polaris lattice physics code, particularly in the design of its input interface.
Dr. Wieselquist’s research interests include sensitivity analysis, uncertainty quantification, data assimilation, verification and validation, lattice physics, depletion methodologies, multi-physics coupling, and user/application interface design.
