  1. The path - way controlling of neptunium in co - decontamination step of purex process, the extraction thermodynamics of amido podand and its usage in recovery of actinides from simulated hllw have been investigated. more than 95 % np were maintained in np ( v ) in 1a extractor and flowed into 1 aw, if enough amount of hno2 was added in feed adjustment and then hno2 scavenger ( urea ) was added before extraction. three kinds of amido podand were synthesized, and the extraction of lanthanides, actinides and some fission products were studied. one of them ( tbopda, n, n, n ', n " - tetrabutyl - 3 - oxa - pantenadiamide ) was used as extractant to recover actinides from hllw. the results of experiments show that more than 99. 99 % actinides were recovered from hllw and separated basically in groups. the main digests are as follows : 1
