William B.J. J Marshall

Senior R&D Staff

B.J. Marshall has been at Oak Ridge National Laboratory since June, 2010.  His primary work areas include SCALE testing and training, validation of computational methods, the criticality safety of commercial spent nuclear fuel storage and transportation,  and the application of sensitivity/uncertainty methods to criticality safety.  B.J. is also involved in nuclear data testing and is also increasingly involved in support of the Department of Energy's Nuclear Criticality Safety Program (NCSP) in research, modeling and simulation, and training roles. B.J. was elected to the NCSP Nuclear Data Advisory Group (NDAG) in 2019, and assumed the role of Vice Chairperson of the International Criticality Safety Benchmark Evaluation Project in June, 2022.

Prior to his time at ORNL, B.J. spent nearly 4 years at the Westinghouse Electric Company working on spent fuel pool criticality safety and PWR reload analysis.  B.J. also spent 4.5 years at Knolls Atomic Power Laboratory, primarily working on reactor physics for new reactor designs.

He holds a Doctor of Philosophy in Nuclear Engineering (December, 2017) and a Master of Science degree in Nuclear Engineering (August, 2001) from the University of Tennessee-Knoxville, and a Bachelor of Science degree in Nuclear Engineering (December, 1999) from the University of Missouri-Rolla (now the Missouri University of Science and Technology).
