摘要

The 2015 ASME Pressure Vessels and Piping Conference includes one dedicated session on fatigue monitoring issues and related assessment methods covering topics on fatigue monitoring approaches worldwide. This session has four papers. The first paper by Reese et al gives an overview on the practical transient temperature measurements at primary circuit components in nuclear power plants operated by E.ON and related operational lessons learned. This kind of fatigue monitoring has been followed since commissioning of the plants at fatigue relevant locations, especially at primary circuit components. The temperature measurement concept has been optimized continuously based on operational lessons learned. Comprehensive surveillance activities yield to a significant amount of information which is used to analyze the component specific health status and which contributes to operational excellence. The specific German authority requirements and long term fatigue evaluation as a significant part of the German ageing management process and break preclusion concept are addressed. An additional relevant aspect is the application of the information gained for the optimization of operation of the plants by minimizing fatigue relevant transients.
