核燃料循环设施磷酸三丁酯/煤油萃取体系燃烧释放行为初步研究

Preliminary study on combustion release behavior of tributyl-phosphate/kerosene in nuclear fuel cycle

磷酸三丁酯/煤油萃取体系燃烧是核燃料循环设施典型的火灾事故,是核燃料循环安全不可忽略的重要研究内容。本文初步展开了磷酸三丁酯/煤油的小面积(77.9~2921.0 mm^(2))燃烧实验研究,通过基础实验初步分析了磷酸三丁酯/煤油的燃烧速率、气体释放组分以及气溶胶释放及其粒径分布规律,并与公开的国外数据成果进行了比较分析。

The combustion of tributyl-phosphate/kerosene is a typical fire accident in nuclear fuel cycle facilities,and it is an important research content of nuclear fuel cycle safety that cannot be ignored.In this paper,a preliminary study on the solvent fire accidents(combustion area 77.9-2921.0 mm^(2))was carried out.The combustion rate of the solvent,the release components of gases,the release of aerosols and their particle size distribution were analyzed by basic experiments.And the differences between experimental results with the published foreign data were analyzed.
