Advancing Innovative Waste Solutions for Sustainable Nuclear Energy
Washington, DC
The landscape of nuclear energy has evolved dramatically since our last International High-Level Radioactive Waste Management Conference (IHLRWM) in 2022. As advanced reactor development accelerates, stakeholders increasingly recognize the essential role of nuclear energy in achieving clean energy goals, enhancing energy security, and providing reliable long-term baseload power. Management of the “back end” of the fuel cycle is an important issue for all countries using or considering nuclear power. As this conference demonstrates, solutions are found through integration of science, technology, and society. IHLRWM provides an international forum for the discussion of all aspects of storage, transportation, recycling, and disposal of used/spent fuel, high-level, and long-lived waste. Innovative approaches, progress, and lessons learned will be shared amongst participants from industry, government, academia, and the interested public. Young generation and student participation is welcomed and encouraged to enrich the exchange of ideas and experiences.
Cooperation is encouraged and expected from numerous professional and technical societies, national laboratories, federal agencies, and commercial organizations throughout the world.
Submissions should contain new data and investigations in scientific or program areas that are of general interest, address problems of interdisciplinary significance, or include in-depth discussions of scientific and technical issues or waste management regulatory and policy issues.
