Final Report on the Research Project Ringhals Diagnostics and Monitoring Stage 11
Rapport, 2007

This report gives an account of the work performed by the Department of Nuclear Engineering (formerly Reactor Physics), Chalmers, in the frame of a research contract with Ringhals, Vattenfall AB, contract No. 566379-003. The contract constitutes Stage 11 of a long-term co-operative research work concerning diagnostics and monitoring of the BWR and PWR units. The work in Stage 11 has been performed between October 1st, 2005 and October 1st, 2006. In Stage 11 we have worked with three items as follows: 1. Beam mode core barrel vibration diagnostics; 2. A literature study of the methodology of the calculation of the conversion factor between core barrel displacement and the relative change in the ex-core detector signal; 3. Evaluation of detector impacting and local and regional stability in R-1. This work was performed at the Department of Nuclear Engineering, Chalmers University of Technology by Imre Pázsit (project leader), Carl Sunde and Christophe Demazière. Contact person at Ringhals was Tell Andersson (project leader).
