中文摘要：

保证核电站的安全可靠运行需要定期对核设施进行安全检查并对其老化状态进行动态安全评估,为充分共享和利用广域范围内由领域内相关企业提供的与动态安全评估相关的信息和服务,在分析目前核电设备动态安全评估现状和需求的基础上,以协同完成核电设备动态安全评估为任务,利用知识网格在实现跨平台互操作、资源与服务共享等方面的特长,搭建了基于知识网格的核电设备动态安全评估体系结构,阐述了网格技术服务平台的基本组织结构及工作原理,并通过实例介绍了基于知识网格的动态安全评估系统运行模式及应用.

英文摘要：

Safety is the most important lifeline of the nuclear power production.To ensure the safe and reliable operation of nuclear power plants,it is important to conduct regular safety inspections of nuclear facilities and carry out dynamic security assessment on the ageing state.In order to share and apply information and service of equipment dynamic security assessment provided by the relevant enterprises in wide area environment,and based on an analysis of the status quo and demand of the equipment dynamic security assessment,and to finish the task of equipment dynamic security assessment coordinately,the system framework based on knowledge grid,which supports for cross-platform interoperability and sharing of resources and services,is constructed.The basic structure and working principle of the grid service platform are described;and the operating mode and application of the dynamic security assessment system is introduced by a case study.
