United States Nuclear Regulatory Commission - Protecting People and the Environment

Thomas Nicholson

Thomas Nicholson is a Senior Technical Advisor in the Division of Risk Analysis of the Office of Nuclear Regulatory Research (RES) within the U.S. Nuclear Regulatory Commission (NRC). He has worked at the NRC for 39 years, primarily in RES. His principal responsibility is to provide technical advice to NRC senior management concerning radionuclide migration in the subsurface at NRC-licensed facilities. His work focuses on research in radionuclide transport at nuclear facilities, primarily due to abnormal, accidental releases in the subsurface. He has formulated and directed numerous research studies, as a senior project manager, involving mitigative techniques for groundwater contamination associated with severe nuclear accidents; radionuclide transport in fractured rock; and integration of subsurface monitoring and modeling strategies. He has provided consulting services to the NRC licensing staff and NRC Regional Inspectors dealing with radionuclide releases and environmental assessments. He co-chairs the Federal Work Group on Parameter Estimation and Uncertainty under the Memorandum of Understanding on Research in Multimedia Environmental Modeling (ISCMEM). He recently co-edited the American Geophysical Union's Special Publication 69 on Groundwater Vulnerability: Chernobyl Nuclear Disaster with Dr. Boris Faybishenko, Lawrence Berkeley National Laboratory. He co-chaired the recent "International Workshop on the Use of Robotic Technologies at Nuclear Facilities." He co-chaired the "International Workshop on the Use of Robotic Technologies at Nuclear Facilities" held at the National Institute of Standards and Technology, February 2 - 4, 2016 (http://www.nist.gov/el/isd/international-workshop-on-the-use-of-robotic-technologies-at-nuclear -facilities.cfm).

He holds a B.S. with distinction in geological sciences from Pennsylvania State University, and a M.S. in hydrogeology from Stanford University. At Stanford, he was a student of Professor Irwin Remson in the hydrogeology program. In 1989, he received the Meritorious Service Award for his scientific excellence. He is a registered Professional Geologist in Indiana, and certified Professional Hydrogeologist in the American Institute of Hydrology. He is an active member of the American Geophysical Union, Geological Society of America, International Association of Hydrological Sciences, the International Hydrogeologic Society, and the National Ground-Water Association.
