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 total neutron cross sections have been measured and resonance parameters determined for 243Cm, 245 Cm, and 246Cm from 0.01 to 30 eV and for 244Cm up to 90 eV. A total thermal neutron cross section at 0.0253 eV was determined for 244Cm of 23 ± 3 b and 2900 ± 450 b for 245Cm. Resonance absorption integrals of 2345 ± 470 b for 243Cm, 605 ± 40 b for 244Cm and 897 ± 180 b for 245Cm were calculated from the resonance parameters.
