Minor actinides like americium are produced during the irradiation of nuclear fuels. These transuranic elements are mainly alpha-emitters and will generate increasing amounts of alpha-damage and helium during spent fuel storage and after disposal contributing to its radiotoxicity. In closed fuel cycles the plutonium and minor actinides separated during spent fuel reprocessing are intended to be incorporated in new fuels for transmutation in fast neutron reactors.
The SUPERFACT experiment, irradiated in 1986-1987 in the Phénix Sodium Fast Reactor (France), provided most valuable transmutation results addressing homogeneous and heterogeneous incineration of minor actinides.
In this work the first Transmission Electron Microscopy investigation of an irradiated and archive fuel with 20% Am and 20% Np is reported. We also studied archive materials with low minor actinides content (2% Am). The results are also discussed in the context of extended storage of spent fuel.
