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).

To resolve a discrepancy in determinations of the 10B(n,α)7Li branching ratio, a new measurement has been made at the National Bureau of Standards (NBS). The measurement was made with a 10BF3 gas proportional counter and monoenergetic 790-keV neutrons obtained at the NBS 3-MV Van de Graaff laboratory. A branching ratio of 0.66 ± 0.03 was obtained. This determination agrees with the measurements of Petree et al. and Davis et al.
