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).

Comparison of many experimental methods and investigation of their systematic errors are indicated for the measurement of the ratio of the epicadmium 238U neutron capture rate to the subcadmium 238U capture rate in a slightly 235U-enriched (1.143%) fuel rod. An explanation of the discrepancy between theory and experiment is given.
