Technical Topics to be discussed

Many utilities have started the analysis of pipe wall thinning phenomenon using the available large amount of measurement data from operating plants. The evaluation covered a wide variety of data pertaining not only to two-phase flows, but also to single phase, such as feedwater and steam systems. The following topics are examples to be presented and discussed in the workshop:

1. Basic Knowledge on equipment degradation and ageing focusing on Erosion and corrosion
2. R&D activities on equipment degradation and ageing
3. Water chemical control
4. Application tool or approaches for diagnostics and prognostics on equipment degradation and ageing in NPPs
5. Feedback of results concerning successes of component management
