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).

A semi-analytic method of solving the neutron transport problem for a homogeneous scattering and absorbing sphere with an isotropic central point source is described. The method consists essentially of a modified Neumann series approach in which the Neumann series is constructed for the difference between the finite problem and the closely related problem in infinite geometry.
