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 problem of optimal estimation of state for deterministic space-time reactor processes has been considered. Based on the proposed dynamic and observation models and the quality index, the problem of estimation has been formulated. The conditions of the optimal solution have been given using the theory of Lagrange functionals. Analytical and numerical solutions of power density estimation in the slab reactor are presented.
