超铀 meaning in English
transuranium
Examples
- The transuranic elements especially the minor actinides ( ma ) in spent fuel represent potential environmental radiotoxicity hazard in the long term
核电站乏燃料中超铀核素，特别是其中的少数锕系核素( minoractinides ，简称ma ) ，对环境具有潜在长期放射性危害性。 - A longer - term option could involve recycling all the transuranics ( plutonium is one example of a transuranic element ) , perhaps in a so - called fast reactor
一种比较长远的做法是，在再次循环中使用所有的超铀元素（钸就是一种超铀元素） ，可能会用在快中子反应器里。 - Equipment for continuous monitoring radioactivity in gaseous effluents - part 2 : specific requirements for aerosols monitors including transuranic aerosols iec 60761 - 2 : 2002 , modified ; german version en 60761 - 2 : 2004
气态排出物放射性连续监控设备.第2部分:包括超铀元素 - With the development of nulear power industry , more and more attention has been given to the spent nulear fuel reprocessing . purex process will remain predominant in the foreseenable future . because the valence of np , one kind of transuranium elements , is easy to interchange , the route of np in purex process is difficult to be controled . a lot of work has been done on the control of neptunium way in the world
随着核电的发展，乏燃料后处理引起了人们的广泛关注。 purex流程在乏燃料后处理中一直占有主导地位。由于超铀元素np的化学价态容易相互转变，使purex流程中np的走向不易控制而倾于分散。 - This paper introduces the latest progress of high level radioactive waste disposal programs in the world , and discusses the key scientific issues as follows ： ( 1 ) the precise prediction of the evolution of a repository site ; ( 2 ) the characteristics of deep geological environment ; ( 3 ) the behaviour of deep rock mass , groundwater and engineering material under coupled conditions ( intermediate to high temperatures , geostress , hydraulic , chemical , biological and radiation process , etc ) ; ( 4 ) the geochemical behaviour of transuranic radionuclides with low concentration and its movement with groundwater : and ( 5 ) the safety assessment of disposal system
在介绍国内外最新研究进展的基础上，重点讨论高放废物地质处置的若干关键科学问题：处置库场址地质演化的精确预测、深部地质环境特征、多场耦合条件下（中（高）温、地壳应力、水力作用、化学作用、生物作用和辐射作用等）深部岩体、地下水和工程材料的行为、低浓度超铀放射性核素的地球化学行为与随地下水迁移行为及处置系统的安全评价。
