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 transport equation governing the deposition of energy carried by fast charged particles in a thermonuclear plasma is derived and solved using a new discrete-ordinates method. This method is shown to be superior to a diffusion theory approximation. Excellent agreement with analytic results for a number of representative test problems has been obtained.
