【摘要】 蒸汽发生器是排出反应堆堆芯产生热量的主要设备,是反应堆冷却剂系统压力边界的一部分。本文建立了蒸汽发生器地震反应分析模型,地震反应分析模型包含汽水分离器组件和管束组件等内件。两个蒸汽发生器模型与一回路管道和压力容器串联,进行地震反应分析。同时,本文还就地震反应分析结果对各参数的敏感性做了研究,其中包括另一台蒸汽发生器、支撑、抗振条设置等的影响,总结了这些特性对分析和设计的指导性意见。地震反应结果对设备支撑和抗振条设置特别敏感,后续电站蒸汽发生器研发时这些因素需着重考虑。更多还原

【Abstract】 The steam generator (SG) serves as the primary means for removing the heat generated within the reactor core and is part of the reactor coolant system (RCS) pressure boundary. The analysis model of SG is created, with moisture separator assembly and tube bundle assembly. The seismic analysis is performed with RCS model. In addition, parameter sensitivities of seismic analysis results are studied, such as the effect of another SG, support, anti-vibration bars (AVBs), and so on. The comments are expected to be significant for future analysis and design. Especially, seismic results are sensitive to support and AVBs setting, which should be focused on in future new type NPP SG’s development.更多还原
