【摘要】 核电厂设备的失效大多源于一种或多种老化机理单独或综合的作用,老化管理是防止关键设备失效、确保核安全的重要手段。本文以国际原子能机构2009年颁布的"核电厂老化管理核安全导则(NS-G-2.12)"为依据,梳理了核电厂从设计、建造、调试,到运行、延寿,直至退役的全生命周期各阶段需要的老化管理工作,分析了各阶段工作承上启下的内在联系,论述了"老化管理核安全导则"的实施,对核电厂设计理念、设备制造、设备鉴定、建造调试、营运管理、检查维修、执照取证、延寿模式、退役模式等带来的新挑战,以及对促进核电厂核安全水平的全面提高,以及对积极发展中的核电行业安全稳定可持续发展的重要意义。更多还原

【Abstract】 Most component failures stem from effects of one or multiple ageing mechanism(s).Ageing management is one of the most significant measures to prevent failure and to ensure safety of nuclear power plants.Based on Nuclear Safety Guideline on Ageing Management(NS-G-2.12) published by IAEA in 2009,the paper summarizes main ageing management activities required for all stages of life cycle of NPPs,including design,construction/manufacture,commissioning,operation,life extension for long-term operation and decommissioning.Interactive relations of ageing management in successive stages are analyzed.Implementation of the IAEA Guideline in comprehensive way will bring about new challenges in senses of design conception,modes of construction,manufacture,commissioning,equipment qualification,O&M,licensing,life extension and decommissioning for NPPs,however,it will be beneficial to enhance nuclear safety level,especially to promote development of nuclear power in China in a safe,steady and sustainable way.更多还原
