摘要
本文在CPR1000核电机组二回路系统放射性物质产生、转移、去除等机理的基础上确定了二回路系统放射性源项的计算模型。计算结果表明,与根据法国的假定和相关设计参数取值得到的结果相比,本文所得源项计算结果要比法国提供的同类机组的源项结果更为保守;而按单台0.5kg/h稳定泄漏率假定得到的计算结果则远小于法国提供的同类机组的源项计算结果。
Computational models of secondary source terms of normal operation is established with CPR1000 nuclear power plants based on the overall process of production, transportation, decontamination of secondary radioactive materials. The results computed with this model and assumption of France is more conservative than that provided by France, but the results computed with ANSI/ANS-18.1-1999 assumption is far less than that provided by France.
