Christepher McKenney has a Bachelor of Science in Nuclear Engineering - Radiation Protection Option from Oregon State University, 1991 and has been with the U.S. Nuclear Regulatory Commission since 1991. He is currently the Chief of the Performance Assessment Branch in the Division of Decommissioning, Uranium Recovery, and Waste Programs in the Office of Nuclear Material Safety and Safeguards. His group is responsible for reviewing and performing modeling related to the long-term impacts of decommissioning, disposal of low-level waste, and waste incidental to reprocessing.
Over his twenty-three years at the NRC, he has primarily worked the waste and radiation protection arenas. He worked on developing guidance and responded to questions related to general radiation protection, low-level waste disposal and uranium recovery issues during the previous update to NRC’s radiation protection standards. He has primarily worked on modeling biosphere transport and establishing exposure scenarios for regulatory compliance in low-level waste, decommissioning, high-level geologic disposal and uranium recovery. Major accomplishments over the years include: (1) being a primary architect of the Memorandum of Understanding with the US Environmental Protection Agency on Decommissioning, (2) his guidance development for decommissioning (NUREG-1757, Volume 2) and low-level waste (NUREG-1573), (3) his work on the BIOMASS program on Reference Biospheres (a method of creating the exposure scenarios) and several IAEA technical documents, (4) his technical direction for NRC activities related to waste incidental to reprocessing at the Savannah River Site, Idaho National Laboratory, and Hanford Nuclear Reservation, and (5) ICRP Report 122 on Radiological Protection in Geological Disposal of Long-Lived Solid Radioactive Waste.
