Dae Chung
U.S. Department of Energy

Mr. Dae Chung has over twenty six years of combined experience in the U.S. government and commercial nuclear industries managing, leading, and performing various nuclear design, engineering, analysis, and safety policy development and oversight activities for a wide variety of programs, facilities, and operations, including: Department of Energy (DOE) defense production facilities; research and test reactors; legacy facilities undergoing environmental cleanup and disposition; and commerical nuclear power reactors.

Mr. Chung began his professional career as a nuclear engineer with Westinghouse Electric Corporation in Pittsburgh in the area of reactor physics and core design and became a senior lead engineer responsible for all aspects of core design, licensing, and start-up and operational support for a number of nuclear power plants in the U.S. and overseas. Since joining the Department in 1989, he has served in increasingly responsible technical and management positions in the Office of Environment, Safety and Health, the Office of Nuclear Energy, the Office of Defense Programs, and the Office of Environmental Management (EM). Mr. Chung has pioneered development of key DOE nuclear safety related polices and directives, including those associated with safety analysis, nuclear facility design, nuclear criticality safety, and long-term safe storage of nuclear materials, which have made significant contribution to assuring safety at many of DOE’s nuclear facilities. Mr. Chung’s expertise in nuclear safety, nuclear facility design and engineering, and safety authorization basis has been widely recognized in the DOE complex as well as national and international nuclear communities. As the Deputy Assistant Secretary for Safety Management and Operations he was responsible for managing an EM corporate policy and oversight program to ensure appropriate implementation of Department’s nuclear safety, Integrated Safety Management System, nuclear materials disposition initiatives, and quality assurance requirements at EM sites and projects. His office was also a focal point for providing day-to-day safety operational oversight, feedback, interface, and direction to the EM site offices including radioactive materials packaging and transportation activities. Mr. Chung was also responsible for managing the EM’s nuclear materials strategic initiatives.

In July 2009 Mr. Chung became the Principal Deputy Assistant Secretary responsible for carrying out program and policy direction for the EM portfolio.

His honors include the Presidential Rank Award and many achievement and special acts awards.

He has a B.S. degree in Nuclear Engineering from the University of Maryland and a M.S. in Mechanical Engineering from the University of Pittsburgh.
