| 摘 要： | 基于美国核管会(NRC)对核电厂主控室可居留性评价的技术要求,并结合我国二代改进型核电厂的设计特点,提出完整的主控室内可居留性人员剂量评价模型。相对于国内现有的计算方法,新模型可兼顾设计基准事故与严重事故情况,采用组合尾流模式计算短期大气扩散因子,结合可居留区域划分及通风系统的设计特点考虑建筑物及通风系统的未经过滤的泄漏对评价计算的影响。

| Abstract: | Based on the NRC technical requirements on NPP control room habitability assessment,and considering the characteristics of the improved second generation NPPs in China,this paper developed a complete dose assessment model for control room habitability.Contrasting to the existing model in China,this model is applicable for DBA and severity accident,and the short term atmospheric diffusion factor can be calculated using the combined wake mode.By considering the zoning of habitable area and the design characteristics of the ventilation system,the effects of un-filtrated air leakage from the building and the ventilation system on the assessment calculation can be considered. |
