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。其为抗震I类设备

须对其进行地震反应分析。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

获得地震载荷下的应力结果。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。研究结果表明

地震反应结果对设备支撑和抗振条设置特别敏感。本文总结了这些参数对分析和设计的指导性意见

供后续核电站蒸汽发生器设计和研发时参考和关注。

Abstract

Background: 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.Purpose: Seismic analysis is required for SG

whose seismic category is Cat.I.Methods: The analysis model of SG is created with moisture separator assembly and tube bundle assembly herein.The seismic analysis is performed with RCS pipe and Reactor Pressure Vessel（RPV）.Results: The seismic stress results of SG are obtained.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.Our results show that seismic results are sensitive to support and AVBs setting.Conclusions: The guidance and comments on these parameters are summarized for equipment design and analysis

which should be focused on in future new type NPP SG’s research and design.
