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).

Thermal-neutron steady-state spectra, in the presence of a 1/E epithermal source of neutrons, calculated in pure and poisoned light water assemblies, using the recent neutron scattering kernel of water suggested by Bansal et al., are found to agree with the recent experimental results of Abbate et al. The effect of different source terms on the steady-state spectra has also been studied.
