摘要

随着现有的核电站继续寻求长期运行，老化管理项目已经被开发出来，以减轻对安全和发电至关重要的反应堆部件的降解过程的影响。检查计划是老化管理的一个组成部分，因为它们为确定维修和更换计划的范围以及指导延长寿命项目的投资计划提供了关键信息。本文提出了一个概率框架，用于与老化管理程序的目标校准定期检查程序的样本量，例如将潜在不合格部件的数量限制在合理的阈值以下。

Calibration of Inspection Strategies in Support of Aging Management Programs: A Probabilistic Approach

As existing fleets of nuclear power plants continue to seek long term operation, aging management programs have been developed to mitigate the effects of degradation processes affecting reactor components that are important to safety and generation. Inspection programs are an integral part of aging management, as they provide crucial information to determine the scope of maintenance and replacement programs and guide investment planning of life extension projects. This paper presents a probabilistic framework for calibrating the sample size of a periodic inspection program with the goals of the aging management program, such as limiting the number of potential substandard components below a reasonable threshold.
