Safety Analysis for Research Reactors

This publication provides practical guidance for performing safety analyses of research reactors. The guidance is based on present good practice worldwide. It covers all the steps required to perform safety analyses, i.e. selection of initiating events and acceptance criteria, rules and conventions, selection of computational tools, and presentation and evaluation of the analysis results. The safety report also discusses various factors that need to be considered to ensure that the safety analysis is of an acceptable quality. It may be applied in varying degrees to all research reactors. The use of calculations and methods such as those included in this safety report may be applied, as deemed necessary, to the preparation of the safety analysis of newly designed research reactors, modifications and upgrades of existing reactors, and new experiments with an impact on safety. It may be also used for updating or reassessing previous safety analyses of operating research reactors.
