Dr. Stephen (Steve) McDuffie has served as a seismic engineer for the Chief of Nuclear Safety (CNS) at the U.S. Department of Energy (DOE) since September 2008. In this position he oversees natural phenomena hazard characterization and design activities at DOE facilities, as well as maintaining operational awareness at several of DOE’s high hazard nuclear facilities. Prior to this he worked ten years at DOE’s Hanford Site in Washington State. In that position he oversaw contractor environmental remediation activities, with a focus on nuclear safety, worker safety, and environmental protection. He has also performed DOE oversight at the Pacific Northwest National Laboratory. Prior to DOE, Dr. McDuffie worked nearly 6 years for the U.S. Nuclear Regulatory Commission (NRC) in Rockville, Maryland. During this time he held several positions, first serving as a geologist reviewing volcanic hazards, seismic hazards, and groundwater flow at the proposed high-level nuclear waste repository at Yucca Mountain, Nevada. He also managed NRC licensing casework for applications to store and transport spent nuclear fuel, and he inspected fabricators and users of spent nuclear fuel and other radioactive material packaging.
Dr. McDuffie holds Ph.D and M.A. degrees in Earth and Planetary Sciences from Johns Hopkins University, where he investigated the physical and chemical differentiation processes in magma. He also earned an MBA degree from Washington State University with a focus on decision sciences and revenue management. Dr. McDuffie has a B.A. degree in Geology from Whitman College, where he graduated summa cum laude and first in his class.
