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 controlled thermonuclear reactor blanket model containing pure lithium metal was expanded by a graphite layer of 15-cm radial thickness. A clear increase of the tritium production due to this graphite reflector could be observed. Measurements of the space-dependent tritium production were carried out and compared with theoretical calculations.
