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 thermal-neutron capture cross section and capture resonance integral for 10.7-year 85Kr have been determined in carefully monitored experiments using 99.992% isotopically pure 85Kr. Values of 1.66 ± 0.20 b and 1.8 ± 1.0 b for the thermal-neutron cross section and resonance integral, respectively, were derived from the increase in 86Kr produced during the irradiation and measured mass spectro-metrically. We conclude from our results that the burnup of radioactive 85Kr in power reactors as a possible means of disposal is not feasible.
