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).

Boron carbide (10B4C) shields are frequently used in the measurement of fast- and intermediate-neutron spectra. In this Note, we present the results of both transport calculations and experimentally measured values for the transmission factors for various activation detectors when covered with a 1.65 g/cm3 10B shield. For unfolding work, the (n,α) absorption by 10B is calculated for each activation detector, and net correction factors are subsequently presented.
