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).

Cross-section sensitivities calculated with one- and two-dimensional models of a fusion reactor shielding experiment are compared. The effectiveness of the two-dimensional calculation in accurately modeling the experiment and detector configurations is demonstrated. At the same time, the validity of a one-dimensional sensitivity study is also demonstrated.
