Review: Accident analysis is an important tool for confirming the adequacy and efficacy of provisions within the defence in depth concept for the safety of nuclear power plants (NPPs). The analysis needs to be consistent, complete, and of good quality. This safety report, based on good practice worldwide, aims to provide practical guidance for performing accident analysis for NPPs with pressurized heavy water reactors (PHWRs), taking into account the specific features of these reactors. Like the other books in the Safety Reports Series, this report covers all the steps required for accident analysis. It looks at the processes by which initiating events are selected. Next, an example is given of high-level acceptance criteria used in the most recent CANDUs (PHWRs of Canadian design) and the technical capabilities that computer codes used in PHWR safety analysis should possess are described. Analysis of individual events are reviewed on an event-by-event basis. Severe accident phenomena and analysis are summarized and suggestions given on what results should be reported for various types of accident.
