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 63Cu(n,α)60Co cross section has been measured by activation relative to the well-known 27Al(n,α)24Na cross section. The 60Co and 24Na activities induced were measured with a 5- × 5-in. NaI(Tl) well-type scintillation detector. The average neutron energy was 14.80 ± 0.02 MeV, with an energy spread of ∼0.3 MeV. As the result, a value of 40.7 mb was obtained for the cross section with an accuracy of approximately ±2.5% (effective standard deviation) on a 1σ confidence level.
