Stability of N-alkylated pyrrolidone derivatives (NRPs) against radiation was examined by irradiation tests with Co-60 -ray. We have been developed a novel reprocessing system using NRPs which have precipitation ability to haxa- and tetravalent actinides in nitric acid media. Degradation rates of NRPs are evaluated by irradiation in 3M nitric acid solutions and mechanism of degradation are discussed in the present paper.
