摘　　要：RELAP5程序由于其非实时计算、无动态输入输出功能以及计算流程难以控制等原因,不适合作为核电站模拟器的热工水力系统程序。RELAPSIM程序在RELAP5基础上经过实时计算功能改造、数据动态交互功能改造、计算流程控制功能改造后,能够完成实时热工水力计算,数据动态交互以及启动、停止、冻结、运行、快照、复位计算流程等功能,满足了作为核电站模拟器的热工水力系统程序的要求。本文主要介绍了RELAP5程序的改造方法和原理以及改造后的RELAPSIM程序测试和结果。Original RELAP5 is a non-real-time code, and has limitation on the data communication and calculation process control, so it is not very suitable for simulator. A new thermal-hydraulic system code for simulator, RELAPSIM, has been developed by employing RELAP5 at NSSE. The course of development consists of three major parts. Firstly, the time control function has been added into the code to meet the requirement of real-time calculation. Secondly, the function of controlled dynamic data communication was improved, thus thermal-hydraulic parameters can be exported from the code and can be input and modified by commands. Finally, the function of calculation process control was embedded in RELAP5 code, which provides the full ability to fulfill the multiple operations, such as starting up, shutting down, freezing, running, snapshoting, and resetting. This paper presents the development activities and the results of assessment by using RELAP5 and RELAPSIM.
