Former director, Nuclear Safety Project
Mr. Lochbaum received a BS in Nuclear Engineering from the University of Tennessee in 1979 and worked as a nuclear engineer in nuclear power plants for 17 years. In 1992, he and a colleague identified a safety problem in a plant where they were working. When their concerns were ignored by the plant manager, the utility, and the Nuclear Regulatory Commission (NRC), they took the issue to Congress. The problem was eventually corrected at the original plant and at plants across the country. Lochbaum joined UCS in 1996 to work on nuclear power safety. He spent a year in 2009-10 working at the NRC Training Center in Tennessee. He retired in 2018. Areas of expertise: Nuclear power safety, nuclear technology and plant design, regulatory oversight, plant license renewal and decommissioning
Dr. Lyman received his PhD in physics from Cornell University in 1992. He was a postdoctoral research scientist at Princeton University's Center for Energy and Environmental Studies, and then served as Scientific Director and President of the Nuclear Control Institute. He joined UCS in 2003. He is an active member of the Institute of Nuclear Materials Management and has served on expert panels of the Nuclear Regulatory Commission. His research focuses on security issues associated with the management of nuclear materials and the operation of nuclear power plants, particularly with respect to reprocessing and civil plutonium. Areas of expertise: Nuclear terrorism, proliferation risks of nuclear power, nuclear weapons policy
Ms. MacDonald received her MA in International Relations and Comparative Politics from Cornell University in 2009, specializing in China. Before coming to UCS in 2011 she worked at the MIT International Science and Technology Initiatives (MISTI) program, and was an instructor at Endicott College teaching courses on international relations. Areas of expertise: Nuclear weapons complex, China
