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).

Fission fragments anisotropy in fast-neutron-induced fission of 235U was measured at neutron energies ranging from 0.3 to 1.4 MeV at intervals of 0.1, 1.6, 1.8, and 2.2 MeV. In the present study, the pairing energy gap (2Δ0) for the highly deformed transition state of the nucleus 236U was found to be 2.0 ± 0.06 MeV.
