Abstract

A variety of degradation modes may challenge the integrity of steam generator (SG) tubing and therefore the stations’ reliability, capacity factor and cost effectiveness. One of the key life?management components for ensuring tube integrity, and thus protecting the safety of the public and the environment, while maintaining cost effective operation of Nuclear Power Plants (NPP), is inspection and monitoring aimed at timely detection and characterization of the degradation.
However, the role of Non-Destructive Evaluation (NDE) has evolved. In addition to the historical role of providing detection tools, current NDE technologies are used as diagnostic tools to gain knowledge that can be related to SG operational parameters. This additional information is often instrumental in tube integrity assessment decisions, fitness-for-service and operational assessments.
This paper discusses the evolution in the overall role of SG inspections and analyzes the motivations behind that evolution. It presents examples that illustrate the current scope of SG inspections as detection and diagnostic tools.
