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).

We have performed three measurements of the 235U fission cross section in the energy range from 0.02 eV to 1 keV. The averaged data are grouped into broad energy intervals to improve the statistical accuracy and to aid in the normalization of higher energy measurements. The uncertainty in the cross sections analyzed in this manner will permit normalization of the values at higher energy with an accuracy of about ±1%.
