Furthermore, the physico-chemical andmicrostructural properties of such fuels, such as chemicalhomogeneity, oxygen stoichiometry (O/(U+Pu) ratio) andcrystallographic structure, have to meet precise criteria forbeing introduced in the reactor core. %G English %2 https://cea.hal.science/cea-02400209/document %2 https://cea.hal.science/cea-02400209/file/Raman-PuFutures_vf.pdf %L cea-02400209 %U https://cea.hal.science/cea-02400209 %~ UNIV-ST-ETIENNE %~ ENS-LYON %~ CEA %~ INSU %~ CNRS %~ UNIV-LYON1 %~ UNIV-ORLEANS %~ CEMHTI %~ LGL-TPE %~ DEN %~ INC-CNRS %~ DEN-MARCO %~ UDL %~ UNIV-LYON %~ TEST-HALCNRS %~ TEST2-HALCNRS
