核电站辐射热点临时屏蔽装置研制现状

Investigation of Temporary Radiation Shielding Facilities in Nuclear Power Plants

在核电站运行和停堆检修期间,使用临时屏蔽装置对辐射热点进行屏蔽是一种常用且有效的辐射防护手段。国内核电站目前使用广泛的辐射热点临时屏蔽装置存在品种单一,功能简单,使用不便等缺点。文章对比总结了国内外辐射热点临时屏蔽装置的应用范围及优缺点,综述了辐射热点临时屏蔽装置的使用情况、发展现状和研究方向,为核电站辐射防护装备的使用和开发提供了参考。

It is a common and effective measure to use temporary shielding device to shield the radiation hot spots during the operation and overhauls period of the nuclear power plants. Domestic nuclear power plants currently widely used radiation hot spot temporary shielding devices, existing a variety of shortcoming, such as little species, simple function, inconvenience, etc.. In this paper, a classified introduction for the application scope and relative merits of domestic and foreign temporary radiation shielding devices are presented. The development status and research direction are summarized, which provide references for the application and development of radiation protection equipment in domestic nuclear power plants.
