Nuclear criticality safety. Analysis of a postulated criticality accident Ingestion-build-103253 In Annex A1 Scope This International Standard specifies areas that are important to study when analysing potential criticality accidents. NOTE 1 It is important that a criticality accident analysis be performed each time a criticality accident is considered credible, due either to criticality contingencies (double batching, procedural violations, etc.) or to the failure of safety provisions (effectiveness of neutron absorber reduced by fire, etc.). NOTE 2 It is
