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.

Come join this interactive workshop and learn about OpenMC, an open source Monte Carlo code. We will introduce some of the basics of the code and also give you a chance to try a few of the more advanced features unique to OpenMC. Come join this interactive workshop and learn about OpenMC, an open source Monte Carlo code. You will be able to run our examples in the cloud via a web browser so no need to install any software before the conference.
