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).

Differential cross sections are reported for elastic and inelastic scattering of neutrons from beryllium. Source neutrons were provided by the D(d,n)3 He reaction at energies from 7 to 15 MeV in 1-MeV steps. Scattered neutrons were observed over a flight path of 4 m at angles ranging from 25 to 160 deg in 5-deg increments. The integrated elastic scattering cross sections agree well with the ENDF/BIV cross-section set. The inelastic scattering cross sections are for the sum of the 1.69-, 2.43-, 2.8-, and 3.06-MeV-state cross sections and fall below the ENDF/B-IV predictions. Inelastic scattering to the 2.43-MeV state in 9Be accounts for less than half of the total 9Be(n,2n) cross sections above 8 MeV.
