摘　　要：研究了反应堆安全分析仿真机的物理模型、热工水力模型、辅助系统建模方法及数值计算技术,用全隐式差分法求解核蒸汽供应系统各个节块、节点的联立方程,在Windows平台下开发了仿真支撑软件与计算软件。用本文开发的安全分析仿真机与Relap5程序对小破口事故进行了计算比较。结果表明,本模型模拟破口事故主要参数的变化规律与Relap5程序的计算结果相符,且本仿真机能够进行实时仿真计算,计算稳定性较好。An investigation of nuclear reactor simulator was made on its physics model, thermal hydraulics model, modeling method for assistant system and numerical calculation technology. The simultaneous equations for each module and node of the steam supply system are solved by full implicit difference method. Then the supporting and calculation softwares for simulation was developed based on Windows system. Calculation and comparison have been done for small break LOCA by the safety analysis simulator developed in this paper and Relap5 code. The results show that the variation of primary parameters for break LOCA of this model accord with the calculation results from Relap5, and the simulator can perform real time calculation with well stability.
