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 parameters for both Taylor and three-exponential representations of the point-isotropic-source dose buildup factors in water have been determined. The three-exponential representation is shown to provide a significantly better fit to the raw buildup factor data than either the Berger or the Taylor representation, while preserving the Taylor representation's most attractive feature, its amenability to integration over extended sources.
