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).

Energy-averaged total neutron cross sections of elemental vanadium were measured from ∼1.0 to 5.5 MeV. Differential elastic and inelastic neutron scattering cross sections were measured from 1.8 to 4.0 MeV. Neutrons corresponding to the excitation of states in vanadium at 321 ± 10, 938 ± 15, 1603 ± 19, 1811 ± 21, 2409 ± 27, ∼2500, 2706 ± 30, and 2773 ± 30 keV were observed. These experimental results were used to deduce an energy-averaged nuclear model suitable for extrapolating the measured values and calculating unmeasured cross sections for applied use.
