查询词典 actinides

The calculation and analysis show that the sub-critical fast reactor is feasible for transmutation of minor actinides and can remain sub-critical when it adds some MA, it is feasible to choose the CDFR for the sub-critical fast reactor research.

计算结果表明：次临界快堆中加入MA后能够保持一定的次临界度且具有较好的嬗变效果，因此，选取示范快堆堆芯作为ADS次临界快堆的参考堆芯研究是可行的。

The present project intends to develop a new compound only containing CHON, which can extract U, Pu and the minor actinides together form the acidic media to integrate the reprocessing.

本课题旨在寻找一种新的只含CHON的化合物，能够从酸性介质中同时萃取铀、钚和次锕系元素，实现后处理一体化。
