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).

Consideration is given to the use of booster rods in a D2O moderated H2O -cooled boiling water power reactor to provide reactivity control to override 135Xe buildup. A booster rod, generally containing highly 235U enriched uranium, is equivalent to a highly effluent fuel assembly. It is shown that the fuel distribution within the most effective booster rod is such that the fuel importance function is flat. Several models of booster rods are evaluated.
