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).

Predicted fission cross-section values, based on systematic trends observed recently by Behrens, are presented in the neutron energy interval from 3 to 5 MeV for 43 isotopes, ranging from thorium through californium. Comparisons with measured fission cross-section values are included for 33 isotopes.
