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.

Advanced Research Projects Agency - Energy (ARPA-E) has sponsored multiple research programs that benefit research and development of advanced reactors. MEITNER and GEMINA programs are two excellent examples among others. These programs further advance the U.S. nuclear energy technologies and increase economic competitiveness of advanced reactors. Thermal-hydraulics research plays an indispensable role in the development, deployment, and operation of advanced nuclear technologies and an important part of these programs. This panel invites panelists to participate in the discussions on the recent status of these ARPA-E supported projects, with the focus on their advances and impacts related to thermal-hydraulics.
