Ringhals Diagnostics and Monitoring: An overview of 30 years of collaboration 1993 - 2023

Report, 2023

A joint research project between Chalmers University of Technology and the Ringhals power plant was conducted regarding development of noise analysis methods and their application to reactor diagnostics between 1995 - 2023. The project was financially supported by Ringhals. The actual contacts and collaboration started actually in 1993, although at the beginning with support from SKI. This report gives a historic overview of the project; its origins, start-up, the problems tackled, and the results obtained. The emphasis is more on providing a full descriptive inventory of the methods and results with explaining their significance, without going in deeply into technical details. For these latter, references will be made to the project reports and other publications. In addition to the research items, the report also includes lists of papers published and conference talks presented from the results of the collaboration, as well as the list of persons contributing to the results, the list of PhD and Licentiate exams, and finally a list of various prizes obtained by the Chalmers participants of the project.


This report constitutes the closing part of the above mentioned long-term collaboration, and is supported financially by with Ringhals, Vattenfall AB, contract No. 4501756928-062. The work in the contract was performed between 1 July 2022 and 30 June 2023.
