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).

The thermal-neutron capture cross section and capture resonance integral for 243Cm have been measured in cobalt-monitored reactor irradiations of nearly isotopically pure 243Cm (99.94%) using cadmium filter techniques. The thermal-neutron absorption (capture plus fission) cross section and corresponding resonance integral for 243Cm have also been measured in a separate experiment relative to 248Cm. Values of σ2200(n, γ) = 130.7 ± 9.6, σ2200(n, f) = 609.6 ± 25.9, I(n, γ) = 214.7 ± 20.3, and I(n, f) = 1575 ± 136 b are reported.
