Zeno Power announced on January 26 that it will get the strontium-90 that it needs to fuel full-scale radioisotope power systems (RPSs) for national security and space exploration missions from the Department of Energy’s Oak Ridge Office of Environmental Management (OREM). Under a public-private partnership, a large legacy RPS known as the BUP-500 that had languished, unused, in storage at Oak Ridge National Laboratory has been transported to an unnamed commercial radiological facility in Pennsylvania—Zeno Power’s subcontractor—where the Sr-90 it contains will be repurposed as heat sources for Zeno Power devices.

The Department of Energy recently shipped half a kilogram of plutonium oxide pellets from Oak Ridge National Laboratory to Los Alamos National Laboratory, the agency announced July 18, marking the largest such shipment since the DOE restarted domestic plutonium-238 production over a decade ago.
