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).

The neutron capture cross section of 59Co has been measured in the energy range from 6 to 200 keV using an 800-ℓ liquid-scintillator detector in conjunction with a pulsed 3-MV Van de Graaff generator as a neutron source. The excellent time resolution of the system, full width of 2.8 nsec at half maximum, permitted derivation of radiation widths for single s-wave resonances to 50-keV neutron energy. Average radiation widths of 0.564 ± 0.024 eVand 0.486 ± 0.016 eV were found for seven J = 3 resonances and ten J = 4 resonances, respectively. No significant correlation between and Γy was found for either spin state. The Maxwellian-averaged cross section for kT = 30 keV was found to be 38 mb over the region from 0.0253-eV to 200-keV neutron energy.
