摘　　要：着重评述了近年来与高放废物深部地质处置有关的地质环境中Pu化学的研究进展,重点讨论了Pu从高放玻璃固化体中的浸出行为、Pu在地下水中的溶解度、配合反应(包括水解反应)、氧化还原反应、胶体的形成等。提出了近期和长期应开展的若干研究课题。The generation, characteristic, and disposal technology of the high level radioactive waste were discussed, anda progress in the study on the chemical behavior of Pu, a transu ranic element possessing the long-term potential risk for the environment, under the geolog ical repository was reviewed. Release behavior of Pu from the high level radioactive glass waste form, the basic chemical reactions of Pu possibly happening in groundwater, including solubility, complexation, redox reaction, and colloidal formation. Some proposals for the further work in China are also suggested.
