Abstract

In the long life extension operation of nuclear power plant, life cycle management technology can provide reliable support for the economic operation of nuclear power plant, and is an important support technology for the evaluation of nuclear power plant’s continuous operation. In order to promote the development of life cycle management technology in nuclear power plants, information technology is used to transform specific problems into standardized databases, relying on the Operation License Renewal Project, the software platform of life cycle management database for important equipment in nuclear power plant is developed. In addition to the storage function of the equipment life cycle management information, the database has the functions of cost calculation and economic comparison of the long-term operation plan. It includes seven modules: Original Information, Program Management, Aging Mechanism, Out-of-date Evaluation, Failure Rate, Economic Analysis and External Feedback. The database built-in nuclear power plant life cycle management typical equipment such as steam turbines, generators, main transformers, and so on, while users can be independent in life-cycle equipment maintenance to add the need to expand the object. It is considered that the acquisition and reliability of cost data, equipment reliability data, and equipment life and failure rate data are the difficulties of life cycle management of nuclear power plants at present.
核电厂生命周期管理数据库平台的开发与应用
在核电站长寿命延寿运行中,生命周期管理技术可以为核电站的经济运行提供可靠的支撑,是评价核电站连续运行的重要支撑技术。为推动核电厂生命周期管理技术的发展,利用信息技术将具体问题转化为标准化数据库,依托“运行许可证更新工程”,开发了核电厂重要设备生命周期管理数据库软件平台。该数据库除了具有设备全生命周期管理信息的存储功能外,还具有长期运行计划的成本计算和经济比较功能。包括原始信息、项目管理、老化机制、过时评估、故障率、经济分析和外部反馈七个模块。该数据库内置核电站全生命周期管理典型设备如汽轮机、发电机、主变压器等,同时用户可以在全生命周期内独立添加需要扩展的设备维护对象。认为成本数据、设备可靠性数据、设备寿命和故障率数据的获取和可靠性是目前核电站全生命周期管理的难点。
