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).

PURNIMA, a PuO2-fueled copper-reflected zero-energy fast reactor at Trombay, was built as a mockup of the proposed air-cooled 30-kW Kalpakkam Pulsed Fast Reactor. This paper describes the salient features of PURNIMA and discusses the calculational methods used and the control philosophy and operational procedures adopted. Important aspects relating to the overall safety are examined in detail. Some of the experiments carried out with this facility are also briefly reported.
