To demonstrate the robustness of extraction systems against radiolytic degradation is nowadays one of the limiting points to ensure a safe and stable operation for advanced nuclear fuel strategies. In this paper is 0 0 addressed the stability of one of most promising extractants TODGA N N N N -tetraoctyldiglycolamide but also the importance of designing realistic model to simulate and study the degradation of the systems. For that new irradiations experiments were carried out where mixture between phases and the oxygen content have been taken into account. Extraction behaviour and composition of the organic phases after g-irradiation have been measured and compared. Although TODGA studies are applicable to many processes currently under development this work is focus on Grouped Actinides Extraction GANEX process development. 0 0 1 Introduction containing TODGA N N N N -tetraoctyldiglycolamide and the malonamide DMDOHEMA N N -dimethyl-N N - In the development of more sustainable nuclear fuel cycle dioctylhexyloxyethyl malonamide as phase modifier to options a future potential scenario involves the transition increase the Pu loading capacity. From this loaded organic from thermal reactors to fast reactors with a closed fuel phase all TRU are stripped by .
