摘要

本文讨论了对美国核电厂在线维护(OLM)实践的研究所获得的见解。OLM在美国已经广泛应用，将一些停电工作转移到电力运行期间进行。通过减少停运工作范围和执行更多的OLM，核电站可以显著减少因停运期间的计划维护而造成的发电损失。在电力供应放松管制、竞争激烈的市场环境中，这一点变得越来越重要。工作周概念和滚动计划是OLM的一些方面，它们使OLM的性能更容易实现。但是，必须仔细审查OLM的范围，以确保OLM所带来的可靠性改进不会因安全系统长期无法使用或其他不当的操作风险而抵消。

A study of online maintenance practices at US nuclear plants

This paper discusses the insights gained from a study of the online maintenance (OLM) practices at selected US nuclear power plants. OLM has been practiced extensively in the US to shift some of the outage work to be performed during power operations. By reducing the outage work scope and performing more OLM, nuclear power plants can significantly reduce generation loss resulting from planned maintenance during outage. This is becoming increasingly important in a deregulated, competitive market environment for electric power supply. The workweek concept and rolling schedule are some of the aspects of OLM that makes the performance of OLM easier to implement. The scope of OLM, however, has to be carefully reviewed to ensure that reliability improvements resulting from OLM are not offset by extended unavailability of the safety systems or other undue operational risks.
