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).

Activation techniques were employed in measurements of cross sections for excitation of the 99.4-min isomeric state at 0.392 MeV in 113In and the 4.5-h isomeric state at 0.335 MeV in 115In from near threshold to ∼10 MeV. Effective cross sections for these processes in standard fission neutron spectra were also computed from these data.
