Long-term degradation (≈ 1,000 years): radiolysis and alkaline hydrolysisQuestion: what is the effect of water-soluble products on the radionuclides mobility? Water infiltration Considered polymer Poly(ester urethane) (PUR) Used as glove for glove boxes Composed of 3 segments issued from these molecules hard segment extender soft segment + 8.9% inorganic fillers +1,8% cross linking agents +0,4% pigments Objectives Characterizing and quantifying water-soluble molecules created by the alkaline hydrolysis of the non-irradiated and irradiated PUR at different doses Understanding the degradation mechanisms PUR under radiolysis Irradiated PUR under hydrolysis Identifying the products than can complex with the radionuclides Being able to model the complexant release kinetics
