En metodik för att utvärdera brandskadescenario på kärnkraftverk

There are a large number of fire scenarios at nuclear power plants that must be analysed to obtain a picture of the fire risk. This report presents a schematic method that can be useful when identifying areas where deeper analysis is necessary. The methodology is based on four possible scenarios. Accepted and generally used calculations methods are available for three of these scenarios. As for the fourth scenario, smoke layer temperature in an adjacent room, there are no general and useful correlations available. For this reason is a large part of this report devoted to describing how such a correlation has been developed. The smaller validation study of the correlation made in the report is promising, but further validation are considered necessary The presented methodology presented provides a rough idea of the fire risks and can be used as a support for decisions on further analysis.
