Reprocessing of spent nuclear fuel aims at improving resource efficiency and reducing its radiotoxicity andheat production in the long term. The necessary separation of certain metal ions from the spent fuelsolutions can be achieved using different solvent extraction processes. For the scenario of the EUROGANEXprocess, the use of the new, modified diglycolamide 2,20-oxybis(N,N-didecylpropanamide)(mTDDGA) was recently proposed to simplify the current solvent composition and reduce extraction offission products. Before further developing the process based on this new ligand, its stability underionizing radiation conditions needs to be studied. For this reason, gamma irradiation experiments wereconducted followed by analyses with high performance liquid chromatography coupled to a massspectrometer (HPLC-MS). The determined degradation rate of mTDDGA was found to be lower than thatof the reference molecule N,N,N0 ,N0-tetra-n-octyl-diglycolamide (TODGA). Many identified degradationcompounds of both molecules are analogues showing the same bond breaking, although alsounreported de-methylation, double/triple de-alkylation and n-dodecane addition products were observed. |
