【摘要】 设备、部件和材料的老化贯穿核电厂从设计到退役的全过程,是一个系统性的问题,需要进行全面研究和管理。文章对老化管理的基本情况和现状进行了介绍,重点整理、描述了压水堆核蒸汽供应系统主要设备材料的典型老化问题及其研究情况。综合分析表明,我国核电厂老化管理工作起步较晚、研究基础较薄弱;尚未形成老化管理及延寿评估的技术和管理体系;在设备材料的老化性能研究方面,除反应堆压力容器外,研究主要集中在设计验证上,没有开展过专门的老化性能研究;涉及老化评价和延寿分析的关键数据缺乏。建议在设备老化的研究方面开展系统性工作。更多还原

【Abstract】 The aging problem of equipments,components,and materials,is a systematic problem which exists throughout the whole process of NPP from design to retirement.In this paper,the basic information and current status of aging research and aging management is introduced,with detailed information about the typical aging problem and research work of main component materials in PWR nuclear steam supply system.Systematical studies have shown that:1) the aging management work of NPP in China has started a little late and the research foundation is relatively weak;2)the technology system and management system of aging management and lifetime assessment has not yet been formed;3) the research work about aging problem of component materials concentrates only on the design verification except for the reactor pressure vessel,and there’s no specialized research work on aging problem;4)there’s a lack of important data on aging evaluation and lifetime enhancement analysis.A systematical research work on component aging problem is suggested.更多还原
