IAEA Coordinated Research Projects (CRP)

Advanced Surveillance, Diagnostics, and Prognostics Techniques used for Health Monitoring of Systems, Structures, and Components in NPPs

2008 - 2011
Demonstration of a thermal shock test

The specific objective of this CRP was to define and coordinate research to support the development of new surveillance, diagnostic, and prognostic (SDP) techniques for monitoring of systems, structures, and components' (SSCs) function and integrity in nuclear power plants. Based on this primary objective, the major sub-categories of research were focused on:

  • Reactor and signal noise analysis
  • Acoustic and vibration monitoring
  • Prognostics and structural material integrity
  • Instrument and equipment condition monitoring

In all four major research areas significant results have been reached that can be used by utility engineers, end users, researchers, managers, and executives, making decisions on the implementation of the subject technologies in nuclear facilities or determining the future direction of research, development, and demonstration (RD&D) in this area. The research was conducted on the latest tools, algorithms, and techniques that had emerged over the last few years, especially in enabling technologies including fast data acquisition, data storage, data qualification, and data analysis algorithms such as empirical and physical modelling techniques. These new tools make it possible to identify problems with plant SSCs earlier and with better resolution. The results helped meet the needs for advanced surveillance, diagnostics, and prognostics to support existing plants, their life extensions and power uprates, as well as future plant designs.

A benchmarking or demonstration effort was also conducted to illustrate that the subject surveillance, diagnostics and prognostics techniques can produce useful and objective results. 18 research organizations have participated actively in this project from 12 Member States.
