燃料组件的地震和失水事故响应——FAMSAP程序的应用
FAMSAP: A CODE TO ANALYZE THE DYNAMIC RESPONSE OF PWR FUEL ASSEMBLIES IN LOCA AND SEISMIC CONDITIONS
-
摘要: 在地震和失水事故下堆芯燃料组件的动力响应程序——FAMSAP主要由两个程序块组成,并包括一个绘图程序,即: FAMSAP=FAMREC+FAFRES+绘图程序其中FAMREC程序块是美国核管会主持开发的程序。FAFRES和绘图程序是根据具体需要研究编制的程序块。文章阐述了FAMSAP的功能和它所应用的模型,同时简要列出用此程序帮助上海核工程研究设计院计算的秦山核电厂燃料组件动力响应的部分结果作为示例。Abstract: FAMSAP is used to calculate the non--linear lateral transient response of PWR fuel assemblies toseismic or LOCA excitation. It is mainly composed of three subcodes: two of which are for physics cal-cuation and another one is for plotting purpose, FAMSAP = FAMREC + FAFRES + PLOT.FAMREC was developed by EG & G Idaho, Inc., to supply the US NRC. FAFRES and PLOT weredeveloped at CIAE, Beijing, China. In the report, the functions of the FAMSAP are described andsome results of dynamic analysis for Qinshan assemblies are given. Finally, several acceptance critiriafor fuel assembly during seismic or LOCA condition are suggested.
