某核燃料循环火灾事故研究装置及初步研究成果介绍

Abstract

Abstract: Fire accident is a typical postulated accident in nuclear fuel cycle facilities, and is the focus of international nuclear fuel cycle safety research. A series of fire research facilities were constructed in China Institute for Radiation Protection (CIRP). The small-scale facility consists of a 200 L cylindrical combustion chamber, and is mainly used for testing the basic parameters of combustibles. The middle-scale and large-scale facilities consist of 20 m³ and 120 m³ rectangular combustion chambers respectively, both of them are mainly used to carry out tests for combustion rate, temperature distribution, radioactive gas and aerosol release share, nuclide release share and filtration efficiency of HEPA. This paper briefly introduces the characteristics of the three experimental facilities, and the research capabilities of each facility were summarized. Further research plans were put forward.

Key words: nuclear fuel cycle, fire accident, test facility, radioactive source term
