摘要/Abstract

摘要： 为保证船用核动力系统运行安全,研究船用核动力分散式控制系统(DCS)深度安全体系。通过分析船用核动力DCS原理架构,提取DCS深度安全特点;基于复杂系统SHEL模型分析DCS运行软件、硬件、环境及人员等深度安全因素;从顶层安全管理、总体安全架构及防护技术体系等3个方面构建船用核动力DCS深度安全防护体系;基于DEMATEL方法计算分析DCS深度安全防护体系要素的影响度、被影响度、中心度和原因度,识别DCS深度安全防护体系的核心及要点。结果表明:针对复杂的船用核动力DCS深度安全影响因素,能够从管理、架构、防护技术等方面进行深度安全防护,尤其需要关注安全教育与培训、安全管理制度、病毒防护、入侵防护等核心要点。

Abstract: In order to ensure operation safety of marine nuclear power system, DCS safety-in-depth system is studied. Firstly, deep safety characteristics of DCS were extracted by analyzing DCS structure of marine nuclear power. Secondly, safety-in-depth factors, including operation software, hardware, environment and livewire, were analyzed based on SHEL model. Then, a safety-in-depth protection system of DCS was constructed from three aspects, top-level safety management, overall safety architecture and safety protection technology. Finally, the influencing and being influenced degree, centrality and causality of system factors were calculated and analyzed based on DEMATEL method, and its key factors and points were identified. The results show that DCS safety-in-depth factors of marine nuclear power are complex and it is necessary to carry out safety-in-depth protection from management, safety architecture and protection technology, especially paying attention to key points of safety education and training, safety management system, virus protection and intrusion protection.

Key words: marine nuclear power, distributed control system (DCS), safety-in-depth, software-hardware-environment-livewire (SHEL) model, safety protection
