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 variances of pulse fluctuations of a periodically pulsed fast reactor have been calculated. The characteristic parameters of SORA, the 1-MW pulsed fast reactor, under development by Euratom at Ispra, have been used as input data. As a result, the relative standard deviation was found to be independent of the duration of the power pulse and the pulse shape and inverse proportional to the square root of the operation power.
