摘要
介绍秦山核电二期工程反应堆系统在一回路管道系统假想的失水事故（ＬＯＣＡ）发生时，系统在流体压力的瞬间变化产生的动态水力载荷作用下的非线性动力分析过程。文中着重介绍了反应堆系统中非线性因素的工程处理方法、非线性动力分析模型的建立和非线性动力分析方法，对于系统ＬＯＣＡ动力响应及其在设计中的应用也作了简要叙述。
The hypothetical loss of coolant accident (LOCA) in the primary piping is assumed in the design of Qinshan Ⅱ reactor system.This accident causes transient pressure variation of the coolant and induces dynamic hydraulic loads on reactor components.This paper describes the nonlinear dynamic analysis procedure of reactor system including the engineering method for nonlinear factors,the establishment of the nonlinear dynamic model and the nonlinear dynamic analysis method.The generation and the application of the LOCA dynamic response for the system are also presented.
