U.K.-based Perpetual Atomics and U.S.-based QSA Global claim to have achieved a major step forward in processing americium dioxide to fuel radioisotope power systems used in space missions. Using an industrially scalable process, the companies said they have turned americium into stable, large-scale ceramic pellets that can be directly integrated into sealed sources for radioisotope power systems, including radioisotope heater units (RHUs) and radioisotope thermoelectric generators (RTGs).

Zeno Power, a developer of nuclear batteries, is to receive americium-241 recovered from Orano’s La Hague nuclear fuel recycling site in Normandy, France, under a strategic agreement announced by the companies on September 24.
