ARDP picks divergent technologies in Natrium, Xe-100: Is nuclear’s future taking shape?
The Department of Energy has put two reactor designs—TerraPower’s Natrium and X-energy’s Xe-100—on a fast track to commercialization, each with an initial $80 million in 50-50 cost-shared funds awarded through the Advanced Reactor Demonstration Program (ARDP). In all, the DOE plans to invest $3.2 billion—with matching funds from industry—over the seven-year demonstration program, subject to future appropriations.
Energy Secretary Dan Brouillette announced the awards late in the day on October 13 in Oak Ridge, Tenn., and said, “These awards are a critical first step of a program that will strengthen our nation’s nuclear energy and technological competitiveness abroad, and position our domestic industry for growth, for increased job creation, and for even more investment opportunity. It’s absolutely vital that we make progress on this technology now.”








On March 9, the Department of Energy’s Office of Environmental Management (EM) released its first strategic plan in several years. Titled “A Time of Transition and Transformation: EM Vision 2020-2030,” and called the Strategic Vision1, the document outlines the past accomplishments in cleaning up legacy nuclear waste and provides a broad overview of the initiatives that EM plans to put into motion over the next decade, “laying the groundwork for a long-term plan to realize meaningful impact on the environmental cleanup mission.”2
The future of nuclear energy is in cogeneration, according to a policy briefing released on October 7 by the United Kingdom’s Royal Society. (The equivalent of the United States’ National Academy of Sciences, the Royal Society, founded in 1660, is the oldest scientific institution in continuous existence.)
