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 prompt neutron multiplicity distribution for the spontaneous fission of 242Cm has been measured. The measurement has been carried out with a neutron multiplicity counter using hydrogen moderation and neutron detection with 3He proportional gas counters. The fission chamber is of a novel design enabling the measurement of fission fragments in the presence of high alpha intensities. We report a value of (242Cm) = 2.532 ± 0.013, which is in turn based on an assumed value for (252Cf) = 3.760.
