摘　　要：安全壳过滤排放系统是核电站应对严重事故的有效缓解措施之一,对几种典型的安全壳过滤排放系统进行了介绍及差异分析;金属纤维过滤器与载银沸石吸附器结合型、高速滑压文丘里洗涤过滤型安全壳过滤排放系统的性能较为优越,尤以高速滑压文丘里洗涤过滤型安全壳过滤排放系统已成为发展趋势;载银沸石过滤单元可提高安全壳过滤排放系统去除有机碘的效率,模块化的设计为国内在役标准高速滑压文丘里洗涤过滤型安全壳过滤排放系统增设该过滤单元提供了便利,建议探讨改进的可行性。The filtered containment venting system is one of the effective mitigation measures for nuclear power plant to deal with serious accidents.Several typical filtered containment venting systems are introduced and analyzed with their differences.The performance of metal fiber filter combined with silver-impregnated zeolite absorber and high-speed sliding pressure venture scrubbing filtered containment venting system is superior,especially,high-speed sliding pressure venture scrubbing filtered containment venting system has become the development trend.The efficiency of the filtered containment venting system for removing organic iodine can be improved by adding a silver-impregnated zeolite filter unit.It is suggested to discuss the feasibility for adding the unit to the standard high-speed sliding pressure Venture scrubbing filtered containment venting system in China.
