Nuclear fuel cycle reimagined: Powering the next frontiers from nuclear waste
In the fall of 2023, a small Zeno Power team accomplished a major feat: they demonstrated the first strontium-90 heat source in decades—and the first-ever by a commercial company.
Zeno Power worked with Pacific Northwest National Laboratory to fabricate and validate this Z1 heat source design at the lab’s Radiochemical Processing Laboratory. The Z1 demonstration heralded renewed interest in developing radioisotope power system (RPS) technology. In early 2025, the heat source was disassembled, and the Sr-90 was returned to the U.S. Department of Energy for continued use.
November 13–17, 2022
Phoenix, AZ|Arizona Grand Resort
This conference provides an international forum for the discussion of the scientific, technical, social, and regulatory aspects associated with the storage, extended storage, transportation, recycling, and disposal of used/spent fuel, high-level and other radioactive waste, including decommissioning waste. As nuclear power is being looked at globally to address climate change, a proactive focus on resolving “back end” of the fuel cycle issues is paramount. Consent-based siting of both centralized interim storage facilities and geologic repositories will be instrumental to fostering this growth. Lessons learned and innovative approaches will be shared amongst participants from industry, government, academia, policymakers, and the interested public. International and student participation are highly encouraged to facilitate knowledge transfer to countries pursuing a nuclear future and to the generation that will be responsible for implementation.
