组件暴露在高温条件下，蠕变或其他时间相关的过程发生遭受退化的性能在长时间的暴露期。这种破坏随后导致开裂和失效。在保证核电站安全运行的同时，延长核电站的使用寿命以获得最大的经济效益是非常重要的。在过去的十年里，人们提出了许多评估剩余寿命的方法。本文综述了目前常用的结构蠕变寿命评估模型。特别强调的是，当这些方法应用于可能包含焊缝的真实部件时，其现状和可行性。
Components exposed to high temperature conditions under which creep or other time dependent processes occur suffer degradation of their properties over long exposure periods. This damage subsequently leads to cracking and failure. It is important to gain the maximum economic benefit from extended operating lives in such plant while ensuring safe operation and over the past decade, many methods have been proposed and used for the evaluation of remaining life. This review examines the currently favoured models for creep life assessment of structures. Particular emphasis is placed on the current status and viability of the methods when applied to real components which may contain welds.
