Perpetual Atomics, QSA Global produce Am fuel for nuclear space power
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).

The relative self-shielded fission rate has been measured for 235U in the energy range from 0.464 to 2150 eV. Absorber thicknesses from 0.5 to 19 g/cm2 of 235U-enriched uranium were used. The measurement was performed to improve on data obtained previously under high-background conditions.
