Sustainable Results

iconRoger J. Mattson was an advisor to the NRC commissioners on policy issues, such as safety goals, safeguards, and Three Mile Island reforms, and led all licensing reviews of advanced nuclear energy systems from 1977 to 1984. Dr. Mattson assisted in onsite response to the accident at Three Mile Island and several other nuclear incidents. He has advised the top-level managers of NRC licensees, National Laboratories and DOE contractors on policy issues and decision-making in the nuclear safety field. He developed NRC licensing standards for safety, radiation protection and environmental protection of uranium fuel cycle facilities and waste management facilities. He participated in safety analysis and field reviews of nearly 150 nuclear facilities in the US, Europe, the former Soviet Union and the Far East.
In two periods, 1977-1980 and 1981-1984, he was Director of NRC divisions with responsibility for regulating radioactive waste management at all US nuclear power plants. He assisted the president of Maine Yankee and Connecticut Yankee in the decommissioning of two nuclear power plants. He led readiness reviews for startup of the Limerick Nuclear Power Plant Unit 2 and the Plant Rocky Flats Site, a special team established by Bechtel for the Hydrogen in Piping and Ancillary Vessels at the Hanford Waste Treatment Plant, and a myriad of other projects involving risk management, systems design and employee concerns at various DOE Sites.
