Technical Meeting on On-line Monitoring of Plant Process and Instrumentation and Control Systems and Components

Background

On-line monitoring techniques have been under development over the past decades for a variety of applications in process and power industries. In the nuclear power industry, on-line monitoring techniques have been considered for instrument calibration verification as well as equipment and plant condition monitoring. The subject of improving the performance of nuclear power plants by utilizing on-line condition monitoring of instrumentation and control systems in plants was suggested by the Technical Working Group on Nuclear Power Plant Control and Instrumentation (TWG-NPPIC) in 2003. It was then approved by the IAEA and included in its work programmes for 2004–2007. In 2008, the IAEA released two publications:

• On-Line Monitoring for Improving Performance of Nuclear Power Plants, Part 1: Instrument Channel Monitoring (IAEA Nuclear Energy Series No. NP-T-1.1);
• On-line Monitoring for Improving Performance of Nuclear Power Plants; Part 2: Process and Component Condition Monitoring and Diagnostics (IAEA Nuclear Energy Series No. NP-T-1.2).

The first report focused on the application of OLM to verify the static (calibration) and dynamic (response time) performance of process instruments in NPPs. Its focus is on instrument calibration verification and extension of calibration intervals of sensors, transmitters and channels. The second report extends the application of OLM to equipment and process condition monitoring, encompassing an array of technologies including vibration monitoring, acoustic monitoring, loose parts monitoring, motor current signature analysis and noise diagnostics, as well as vibration analysis of the reactor core and the primary circuit.

Recognizing the relevance of the above-mentioned issues, the members of the TWG-NPPIC at their 2023 meeting recommended that the IAEA should update the publication based on the recent development of digital technologies and on-line monitoring techniques for advanced surveillance, maintenance optimization, diagnostics and prognostics.

In response, the IAEA is developing new revision of the Nuclear Energy Series publication entitled On-line Monitoring for Improving Performance of Nuclear Power Plants; Part 2: Process and Component Condition Monitoring and Diagnostics (IAEA Nuclear Energy Series No. NP-T-1.2) to integrate the recent developments as on-line monitoring techniques have been under development since the last publication.

The purpose of the event is to finalize this IAEA Technical Publication.
