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 Milne problem for isotropic scattering for one speed and for the conservative case, (c = 1), is solved by using the full-range completeness property of Case’s eigenfunctions. Explicit numerical results are derived by iterating on a very rapidly convergent Fredholm integral equation, and the results thus obtained are in excellent agreement with those obtained previously by the use of Case’s half-range completeness theorem. Since for multigroup formulations the full-range completeness is more easily proved (as compared to the half-range completeness), it is felt that the present approach may prove useful.
