  • Some specific aspects of homogeneous Am and Np based fuels transmutation through the outcomes of the SUPERFACT experiment in Phenix fast reactor


In this study the following effects were analysed for different Am and Np based fuels: (i)interaction in the fuels with austenitic steel cladding; (ii) the consequences of the specific production of fission gases in terms of the stress supported by the cladding; (iii) self shielding effect in irradiated fuel pellets. The advantages of using fast reactors for the transmutation of actinide based fuels are shown; there are no side effects and global behaviour is similar to that of standard oxide fuel. It is anticipated that a high rate of transmutation could be attained. However, the large quantity of helium produced by fuels with a high americium content may impose limits on the irradiation due to the stress levels induced on the claddings.
