IMORN-31 International Conference on Reactor Noise

TU Delft, 9-12 September, 2024, Delft, The Netherlands

Reactor noise analysis has always been a vibrant research field providing many new insights and applications contributing to safe nuclear power. Modern hardware and new numerical techniques for data management, feature extraction, dimensionality reduction, and machine learning give impetus to a strong revival of research and applications in this field.

For this reason, we organized a follow up of the renown International Meeting On Reactor Noise Series (IMORN) to gather in an informal setting and exchange ideas for the extraction and use of information hidden in signals from nuclear installations.

The IMORN-31 meeting was held from 9-12 September 2024, at the TU Delft Reactor Institute in the Netherlands, and is a follow up of the IMORN-30 meeting in Göteborg, Sweden. The slides can be downloaded here. More information on the conference can be found at the IMORN-31 website.

The organizers: Oszvald Glöckler, Jan Leen Kloosterman, Imre Pázsit.
