Dr. Apted has more than 25 years of experience in nuclear-waste disposal R&D, primarily in the design and testing of engineered barrier systems (EBS), hydrogeochemical modeling, and safety assessment. For the Electric Power Research Institute he is the R&D manager for post-closure risk assessment studies regarding disposal of spent nuclear fuel and high-level waste at the Yucca Mountain site, Nevada, USA. He is a member of the International Technical Advisory Committee (ITAC) to the Nuclear Waste Management Organization of Japan (NUMO), and serves as a coordinator for NUMO's International Tectonics Committee. Dr. Apted is Chairman of the EBS and Technology Support Group for STUK, the safety authority in Finland. He also has consulted for nuclear waste repository implementation and regulatory agencies in Sweden, Switzerland, South Africa, Canada, Taiwan, and South Korea. Professor Joonhong Ahn is a Professor of Nuclear Engineering at the University of California, Berkeley. He also serves as Geological Faculty Scientist at Lawrence Berkeley National Laboratory. Since 2010, he serves as a member of the international review committee for 2010 report compiled by Nuclear Waste Management Organization of Japan (NUMO) Fellowship Program by Office of Civilian Radioactive Waste Management, US Department of Energy. He has been participating in the Coordinate Research Project by International Atomic Energy Agency for the topic of Role of Partitioning and Transmutation of High-Level Radioactive Wastes for Minimization of Environmental Impacts from Nuclear Fuel Cycle since 2002.
