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 feasibility of the weighting technique to determine fast neutron capture cross sections when applied to NaI pulse-height measurements is investigated. This technique is applied to the measurement of the capture cross section of 181Ta at 0.5- and 3.0-MeV neutron energies. The results are compared with those obtained using the spectrum integrated method.
