ISO 27467:2008 specifies areas that it is important to study when analyzing potential criticality accidents.
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.).
It is important that the criticality safety specialist be mindful that the process of evaluation developed in ISO 27467:2008 does not cater to the unforeseen, since any actually occurring criticality accident will probably result from a scenario not envisioned or from failure to comply with prevailing regulations.
ISO 27467:2008 does not address detailed administrative measures, for which the responsibility lies with the public authorities, nor does it deal with criteria used to justify the accident criticality analysis of a nuclear facility.
ISO 27467:2008 does not apply to nuclear power plants.
