Perspectives in using Raman spectroscopy for characterizing the microstructure of plutonium-bearing materials
Résumé
In the frame of the development of uranium-plutonium
mixed oxide fuels for Sodium-cooled Fast Reactors (SFRs),
characterizing nuclear materials by various techniques is
paramount.
These fast neutron reactors imply the use of a (U,Pu)O$_{2-x}$
ceramic fuel with a Pu/(U+Pu) content between 19 and
30 mol.%. Furthermore, the physico-chemical and
microstructural properties of such fuels, such as chemical
homogeneity, oxygen stoichiometry (O/(U+Pu) ratio) and
crystallographic structure, have to meet precise criteria for
being introduced in the reactor core.
