Zeno Power says it has gained access to radioactive material destined for its first full-scale radioisotope power systems under the terms of a partnership with the U.S. Department of Energy.
The transfer of the material from Oak Ridge National Laboratory in Tennessee benefits Zeno as well as the Department of Energy: Zeno — which has offices in Seattle and Washington, D.C. — gets the strontium-90 fuel that it needs for its next-generation RPS. At the same time, the DOE gets an opportunity to put a decades-old RPS to good use instead of putting it through a costly disposal process.
“This transfer highlights another unique approach our team has taken to accelerate environmental cleanup at Oak Ridge,” Jay Mullis, manager of DOE’s Oak Ridge Office of Environmental Management, said today in a news release. “This is a win-win scenario that’s removing a significant source of radioactivity at a savings to taxpayers, while also supporting nuclear innovation.”
Radioisotope power systems, also known as radioisotope thermoelectric generators or RTGs, have been used for decades to provide off-grid power for space missions and other applications. Such devices convert the heat generated by radioactive decay into electricity. Plutonium-238 is often used for space applications, but Zeno is working on a system that uses strontium-90 as an alternative heat source.
