摘　　要：钠冷快堆钠水反应事故的仿真是钠冷快堆仿真机开发的一个难点.为了解决这个问题,基于钠冷快堆蒸汽发生器内传热管水泄漏导致的钠水反应事故的数学物理方程,设计了一个钠水反应事故的模拟程序.使用SimTherm热工水力仿真程序,针对钠冷快堆的结构,设计了适用于钠水反应事故研究的钠冷快堆二回路模型.通过将钠水反应事故模拟程序与SimTherm进行耦合运行,实现了钠冷快堆钠水反应事故的仿真,为钠冷快堆仿真机的开发提供了一种新的思路.The simulation of sodium-water reaction accident is the difficulty in the development of the simulating system of sodium cooled reactor.In order to solve this problem,a simulation program of sodium-water reaction accident was designed based on the mathematical physical equation of sodium-water reaction accident caused by water leakage in heat transfer tube of sodium-cooled fast reactor steam generator.Based on SimTherm thermal-hydraulic simulation program and the structure of sodium-cooled fast reactor,a second-circuit model of sodium-cooled fast reactor was designed for the study of sodium-water reaction accidents.By coupling the simulation program of sodium-water reaction accident with SimTherm,the simulation of sodium-water reaction accident was realized,which provides a new idea for the development of sodium-cooled fast reactor simulator.
