关于控制室可居留性若干问题的讨论

Discussion on Control Room Habitability Assessment

从控制室包络(CRE)边界的完整性、控制室可居留性分析所用源项以及影响控制室剂量后果的其他因素等几个方面,结合美国及我国在控制室可居留性方面的管理规定及我国核设施在控制室可居留性方面的研究现状进行讨论,建议我国核设施应考虑通过进行CRE完整性测试来获取CRE渗入量的数据,为控制室可居留性分析提供输入参数,此外,在控制室人员后果计算中应考虑不同事故及可能的不同路径作系统的分析。

The discussion on control room envelope integrity, source term analysis in habitability assessments and other impact factors for dose consequence is provided combined with regulatory requirements and the current status of domestic NPPs. Considering that the infiltration is an important factor for control room habitability assessment, CRE integrity test should be performed to demonstrate the CRE＇s infiltration characteristics. The consequence assessment should be performed based on different DBAs arid different pathways, such as pathways internal to the plant.
