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).

A model that includes fission for predicting particle production spectra from medium-energy nucleon and pion collisions with uranium nuclei has been incorporated into the nucleon-meson transport code HETC. A variety of calculated results obtained with this revised code for protons incident on uranium targets have been obtained and are compared with experimental data and with the calculations of other investigators. For incident proton energies 1 GeV, the calculated results are in good agreement with several, but not all, of the available experiments.
