摘要

核电厂安全壳过滤排放系统是严重事故的重要缓解措施之一,能够通过过滤、排气、降压,防止安全壳发生超压失效。目前,许多国家已重启或开启了对安全壳过滤排放系统的研究工作,安全壳过滤排放系统有可能成为全球核电厂的标准配置之一。中国国家核安全局颁布的核电厂安全法规也要求安全壳应配备有足够过滤能力的排气系统。国内在运、在建以及规划中的大多数核电厂都配备了安全壳过滤排放系统,以文丘里洗涤类型为主,本文讨论安全壳过排放系统在国内的应用,研究现状及发展趋势。

Abstract

To mitigate severe accidents (SAs) in nuclear power plants (NPPs), filtered containment venting system (FCVS) is designed to prevent the potential containment overpressure failure through the filtered venting process. So far, many investigations and research works have been initiated or resumed particularly about the reinforced FCVS, which is expected to become the standard configuration of most NPPs. The NPP safety regulation, the safety regulation of nuclear power plant design (HAF102) issued by the Chinese NNSA, requires that NPPs should have venting systems with adequate filtration. Now, either most NPPs of operating reactor units under construction or more units planned in China are going to be equipped with FCVS, with priority of Venturi scrubber type system. At present, major nuclear energy companies, research institutions and universities are initiating or accelerating research and engineering projects on FCVS designs with enhanced performance.
