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).

Excellent agreement has been found between a University of Florida neutron pulse propagation experiment and a two-dimensional space-time calculation. Discrepancies previously reported between the experiments and one-dimensional WIGLE calculations are now attributed to inadequate treatment of the kinetic distortion caused by the presence of transverse reflectors.
