Dan Walker, Executive Director
Dan came to the valley seven years ago after bouncing between coasts. After receiving his bachelors degrees from Northeastern University in Boston and Reutlingen University in Germany, Dan went on to work with the Department of Defense. As a senior analyst with BAE Systems and MTC Technologies, he led contracting teams out of Quantico Virginia for seven years. Specializing in DoD procurement programs specific to integrating joint capabilities between military branches, Dan managed teams of analysts and subject matter experts on an array of DoD concerns, notably missile defense systems.
While traveling between the San Francisco area and Virginia, Dan also found time to complete his certification as a wilderness EMT, and later as a Paramedic. An avid climber and skier with professional training from the American Mountain Guides Association, Dan also worked with military expeditions to climb peaks in Alaska, Argentina, and Peru. After moving to Jackson and enjoying the shortened commute to granite walls and deep powder for a few years, Dan transitioned away from the DoD and went to work with a local company, Cloudveil Mountain Works. His three years at Cloudveil afforded Dan the opportunity to become more directly involved with several community organizations and environmental advocacy groups.
Dan came to work with KYNF in the fall of 2011 with the focus of working with the INL's cleanup efforts. An ardent advocate for environmental stewardship, Dan continues to ensure that our community is educated on the safety and viability of the programs that are guided by our energy needs.
Mark Sullivan, Attorney
Mark works as KYNF's attorney. Armed with an LL.M in Environmental law, Mark started his career with Riverkeeper, Inc., the Hudson-river based environmental watchdog where Mark spearheaded Riverkeeper’s watershed protection program. Mark then spent nearly five years at the Wall Street firm of Carter Ledyard & Milburn in its prominent environmental practice group, focused on urban environmental issues such as air and water pollution, traffic and noise. Yearning for open spaces, in 2003 Mark and his family relocated to Jackson Hole. Today, Mark lives with his wife, architect Nona Yehia, and their two children, Wyatt & Lucy, in Wilson, where Mark has his own diverse practice of law. Mark and his family enjoy all that Jackson has to offer, and work hard to give back to their community.
Mark became involved with KYNF in 2004 when the Department of Energy first proposed using the Advanced Test Reactor to make Plutonium-238. Volunteering his time, Mark delved deeply into that Project's environmental impact statement, unearthing alarming realities about the dangers of using a 40 year old reactor to manufacture plutonium. Thereafter, Mark represented KYNF in NEPA and Freedom of Information Act litigation, and prevailed in forcing the Department of Energy to release thousands of pages of safety documents relating to the Advanced Test Reactor. With the help of Mark's advocacy, KYNF successfully derailed the PU-238 project. Mark is a fierce advocate and will continue to assist KYNF as it monitors DOE operations in Idaho.
TECHNICAL ADVISORY BOARD
Tami A. Thatcher
Tami is a mechanical engineer with over twenty-five years of engineering experience specializing in probabilistic risk assessment and safety analysis of DOE nuclear facilities. She has extensive experience analyzing the risk of plant operations for the INL’s Advanced Test Reactor. Tami was a persistent investigator of safety issues, submitting many more Unreviewed Safety Questions (USQs) than peers due to thorough investigation of safety issues and knowledge of plant systems, accident risk models, safety basis, and safety regulations and deeply caring about nuclear accident prevention. She has extensive experience in facility safety documentation and analyses involving the “Nuclear Safety Management” rule, 10 CFR 830.
Her goals are to promote transparency of Department of Energy Idaho National Laboratory safety management and improve public understanding of the serious risks and potential accident consequences posed by INL facilities. She will work to monitor and influence DOE, State, and federal decision-making regarding INL facilities, existing INL spent fuel, and the future of spent fuel and nuclear energy in the US.
Kathy has 31 years of experience supporting the safe management of radioactive waste. Her experience ranges from the management of uranium mill tailing to spent nuclear fuel. She has been directly responsible for over $1 B in projects for large, complex nuclear facilities. She has a strong reputation for strategic planning, and knowledge of national and international requirements and skills in dealing with a broad range of stakeholders. She was formerly the vice president of waste management nuclear services, and a director of the Environmental Restoration Program at INL. Her background in water resource management (water chemistry) has led to over three decades of experience in radioactive waste mitigation and remediation.
