Performance analysis of coated plutonia particle fuel compact for radioisotope heater units

Investigation of physico-mechanical properties of ceramic oxide kernels for nuclear applications

“…Since the coated particles and ceramic fuel kernels are physically and chemically stable, they would be very suitable for eventual geologic disposal after appropriate conditioning. Recently, plutonia kernels were proposed for potential use in advanced radioisotope heater units and radioisotope power systems [5].…”
