摘要:
核电厂严重事故工况下的仪表可用性评价一般采用曲线包络法。但由于曲线包络法存在一定的局限性,应用PSpice电路仿真方法对其进行补充,对电路仿真建模方案进行分析。根据严重事故工况环境现象及仪表失效相关数据库,结合核电厂仪表的特点,建立电路仿真模型,将仿真结果同三里岛事故仪表分析报告进行对比验证。结果表明,采用的建模方案具备合理性。
摘要(英文):
The method of enveloping is used commonly in the instrument survivability evaluation in severe accident in nuclear power plants (NPPs). Due to the limitation of this method, this paper studies the method of circuit simulation by PSpice as complementary. Based on the databases of phenomenon and effects on instruments in severe accident, we analyze and summarize the key condition factors that threats most. And according to the characteristics of instruments in NPPs, we create the circuit simulation models that present the instruments in NPPs. Com...
