Progress in Radiation Chemistry of Extractants for Nuclear Fuel Reprocessing

The research work of Chinese scientists in the radiation chemistry of extractants used in nuclear fuel reprocessing in 30 years has been reviewed in this paper, particularly the progress in radiation chemistry of tri-n-butyl phosphate （TBP） has been reported mainly. Moreover, current studies on the radiation stability of other novel extractants have been discussed. Finally, some challenges and prospects in this field are suggested.
