基于WEB架构的轻量化核电站严重事故模拟系统实现

Implementation of a Lightweight Nuclear Power Plant Severe Accident Simulation System Based on WEB Architecture

摘要: 福岛核事故后，对严重事故现象的认识及对事故工况预防缓解措施的处理等方面的培训及研究的需求增强，而传统的核电站严重模拟机规模庞大、造价昂贵、启停繁琐、维护复杂，对高校、设计院所不适用。基于上述背景，本文开发了一套基于WEB架构的轻量化核电站严重事故模拟系统，重点对系统功能、实现方案、技术架构、实施流程等进行研究，针对特定用户场景，提升事故模拟性能及部署能力，扩充传统核电站严重模拟机应用边界，系统运行稳定，功能、性能指标满足用户要求，已应用于多个高校教学培训及科研院所辅助设计验证。

Abstract: After the Fukushima nuclear accident, there has been an increasing demand for training and research on the understanding of severe accident phenomena and the handling of preventive and mitigation measures for accident conditions. However, traditional nuclear power plant severe sim-ulation machines are large in scale, expensive in cost, cumbersome in startup and shutdown, and complex in maintenance, which are not suitable for universities and design institutes. Based on the above background, this paper develops a set of lightweight nuclear power plant severe accident simulation systems based on WEB architecture, focusing on the system function, implementation scheme, technical architecture, implementation process and other research, aiming at specific user scenarios, improve the accident simulation performance and deployment capability, expand the application boundary of traditional nuclear power plant severe simulator. This system runs stably, and its functions and performance indicators meet users’ requirements. It has been applied to the teaching and training of many universities and research institutes to assist in design verification.
