摘要/Abstract

摘要： 核能的广泛利用伴随着乏燃料的产生和累积,乏燃料后处理技术将乏燃料再循环利用受到重要推崇,但乏燃料后处理设施的安全是发展后处理技术的重要前提,后处理中的有机相着火事故作为后处理的设计基准事故之一,得到了国内外的重要关注。为分析后处理厂在有机相着火事故中,有机相的燃烧行为、放射性气溶胶的扩散和沉积、高效过滤器的性能等,美国、日本等国分别建立了实验设施并进行了有机相燃烧的实验研究。本文综合评述了国内外关于后处理厂有机相着火事故的试验技术方法和研究结果,提出了当前研究存在的问题以及未来有待进一步研究的方向。

Abstract: With the wide usage of nuclear energy,more and more spent nuclear fuel would be produced and accumulated.The spent fuel reprocessing technology recycling the spent fuel is advanced,but the security of spent fuel reprocessing facility is an important premise for the development of the spent fuel reprocessing technology.The solvent fire as one of the design basis accidents,has been an important concern at home and abroad.In order to analyse the combustion behavior of solvent fire,diffusion and deposition behavior of radioactive aerosol,performance of high efficiency filter and so on,the United States,Japan and other countries have established the experimental facilities and the combustion of solvent solution was studied.In this paper,the experimental methods and research results of solvent fire accident are reviewed,and the existing problems and future research directions are put forward.

Key words: solvent fire, tributyl phosphate, kerosene, spent fuel reprocessing plants
