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).

In this Note we report on a technique for determining a two-dimensional time-dependent response function using a one-dimensional solution of the transport equation for a homogeneous medium. Basic to this technique is the calculation of the adjoint function. We have determined the asymmetric energy deposition rate in air from a spatial asymmetric source as an example of the method.
