  5. 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

    鎿走向控制研究中通過調價階段加入亞硝酸、而萃取前清除亞硝酸的獨特辦法可以將大於95的鎿趕入1aw 。合成了三種酰胺莢醚萃取劑，研究了它們對錒系和裂片元素的萃取熱力學，通過條件實驗選擇了其中一種莢醚tbopda （ n ， n ， n 』 ， n 』 ?四丁基? 3 ?氧戊二酰胺） ，進行了從模擬高放廢液中分離錒鑭系元素的工藝研究，錒系的回收率大於99 . 99 ，並且基本上實現了錒鑭元素的組分離。其要點如下： 1
  6. This research has studied the microstructure of cathode materials systematically by the means of high resolution transmission electron microscopy and scanning electron microscopy, surveyed the electron emission performance of la2o3, - mo, la2o3 - y2o3 - mo, la2o3 - sc2c > 3 - mo cathode with the self - designed electron emission surveyor and analyzed the elements changing of the surface of mo - la2o3 - sc2c > 3 cathode in - situ. while it was heated to different temperature. at last, the relationship of the microstructure of cathode, diffusion of active matter and electron emission performances has been discussed

    本研究採用高分辨掃描電鏡、透射電鏡對稀土鉬鎢陰極材料的顯微結構進行了系統研究；利用本課題研究組設計研製的電子發射測量儀對la2o3 - mo ， la2o3 - sc2o3 - mo ， la2o3 ? y2o3 - mo三種陰極（以下稱鑭?鉬陰極、鑭鈧?鉬陰極、鑭釔?鉬陰極）的發射性能進行了測量；利用經改造后的俄歇電子能譜儀「原位」分析了發射性能較好的鑭鈧鉬陰極在不同溫度下表面活性元素的變化情況。
