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).

Fewer neutrons are produced from 11B(11B, n) than from 11B(p, n)11C for temperatures from 100 to 800 keV. For temperatures below 300 keV, 11B(d, n)12C produces more neutrons than either of these reactions if the normal isotopic mixture of hydrogen is used. Potentials generated by the double-folding method and tested against 7Li + 7Li data were used to generate 11B + 11B cross sections for energies where there were no measurements.
