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).

Neutrons and gamma rays emitted by a test fuel element were imaged through a linear array of pinholes. The ionizing radiations formed optical images on a plastic scintillator that was viewed by an intensified television (TV) system. The TV records provided a sequence of twelve 16-ms frames spanning a 2860-MW, 315-MW-s Transient Reactor Test Facility transient. Data show radial expansion of the test fuel pin.
