系统工程方法论在核反应堆数字实验中的应用研究

核反应堆工程实验系统的复杂性一直是制约核反应堆工程实验技术攻关和创新的重要因素之一。为提升应对核反应堆工程实验系统复杂性的能力和手段，引入数字实验概念，目的是建立适用于核反应堆工程实验全生命周期的统一高效的业务执行环境。本文基于系统工程方法论详细阐述了数字实验平台的顶层架构，包括由V模型和业务场景图构成的业务流程架构，由数据模型化知识化逻辑图构成的实验基础架构，以及由业务层的业务管理系统、应用层的实验设计仿真环境系统、知识层的实验知识系统和资源层的基础功能系统构成的平台功能分层架构，并以“华龙一号”（ACP1000）二次侧非能动余热排出系统（PRS）实验系统为对象进行了应用验证。验证结果表明:上述的架构具有较强的可行性，可作为数字实验平台开发的整体逻辑框架。 

Application of System Engineering Methodology in Digital Experiment of Nuclear Reactor Engineering

Complexity of nuclear reactor experiment systems always is one of important factors which limit? the experimental technology development and innovation. Digital experiment of nuclear reactor engineering is introduced to improve the ability to deal with the complexity of experiment systems. The objective of digital experiment is to establish a unified and efficient work environment throughout the whole life cycle of the experiment programs of nuclear reactors. The high-level system architecture of digital experiment is constructed based on the method of system engineering in this paper. It consists of business architecture which is constituted by V model and business scenario diagram, experimental infrastructure architecture which is constituted by logic diagram of intellectualization, and layered architecture of digital experiment platform which is constituted by business administration system in the business layer, experimental design simulation environment system in the application layer, experiment knowledge system in the knowledge layer and basic data administration system in the resource layer. The application example for PRS experiment validates the effectiveness of the above system architecture of digital experiment as the whole logic framework of the digital experiment platform.
