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).

An experiment to measure the detailed energy, angular, and spatial distribution of neutrons originating from a 14-MeV neutron source in liquid air is presented. The neutron spectra are measured with a proton-recoil NE213 scintillator combined with a collimator. The measurements cover the energy range from 2 to 18 MeV at eight different angles from 0 to 90 deg. The distance between the neutron source and the measurement position varies from 60 cm (52 g/cm2) to 150 cm (130 g/cm2) in liquid air. The results are discussed and compared with known theoretical neutron transport calculations.
