Experience from screening and analysis of safety related events at Swedish nuclear power plants

Improving safety by collecting and disseminating information from safety related events, both from Swedish and foreign nuclear power plants, has been practised at the Swedish Nuclear Power Inspectorate since at least 1974. Analyses have been carried out and utilized for different isolated purposes. Not until recently, however, has a more interdisciplinary oriented and systematic effort been possible. Screening of domestic Licensee Event Reports and reports of foreign origin, and subsequent analysis of the selected events, are performed in a systematic way. Both the screening group and the different project groups consist of persons from different departments and with different skills. Experience from one and a half years of work with these project groups is presented. (author). 3 figs
