Nuclear criticality safety. Analysis of a postulated criticality accident1 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

(3) Metallic products and coatings on metallic products are not considered in the determination scheme of this Technical Specification since the test methods in CEN/TS 16637‑2 (tank test) and CEN/TS 16637‑3 (column test) are not appropriate for the testing of these construction products due to a different release mechanism (solubility control)
