基于自主化严重事故分析软件NUSSAP的IAEA严重事故模拟机开发
Development of the IAEA Severe Accident Simulator Based on Autonomous Severe Accident Analysis Program NUSSAP

本文针对国内自主化严重事故计算程序普遍没有较为灵活的API接口或与外部程序直接交互的功能，结合中核武汉核电运行技术股份有限公司为国际原子能组织(IAEA)提供的严重事故原理模拟机软件的框架，对使用自主化核电厂仿真严重事故分析程序(NUSSAP)开发严重事故原理模拟机的方式方法以及设计理念进行了阐述。主要介绍了教控控制、系统外部接口、逻辑控制等交互功能设计。各研发单位可参考该项目的设计理念，结合自主化程序的程序结构特点，进行程序API开发，进一步扩展程序的应用场景。
In view of the fact that domestic autonomous severe accident calculation programs generally do not have flexible Application Program Interface (API) or the function of direct interaction with external programs, this paper combines the framework of severe accident principle simulator software provided by China Nuclear Power Operation technology Co., Ltd. for the International Atomic Energy Agency (IAEA). The method and design concept of developing the severe accident principle simulator using the autonomous Nuclear Simulation Severe Accident Analysis Program (NUSSAP) are described. This paper mainly introduces the interactive function design of operating control, external interface of the system, logic control. Research and development institutions can refer to the design concept of the project and combine the program structure characteristics of the autonomous program to develop the program API and further expand the application scenario of the program.
