Drum or disc excessively worn, excessively scored, cracked, insecure or fractured.

The structure of a unit body, any equipment attachments and lifting and jacking points shall be designed such that no cracks, no significant permanent deformation or ruptures occur under the load cases defined in Chapter 5 of EN 12663-2:2010.

4. Recalls, however, that the stress tests initiated by the Commission and ENSREG were limited in scope and were primarily intended to assess the robustness and preparedness of NPPs in the face of extremely severe external events; considers, therefore, that the stress tests were primarily aimed at assessing the robustness and preparedness of NPPs against such severe external events and were not and could not be intended to replace the detailed safety reviews of NPPs which are carried out under the national competence of the Member States for assessing the nuclear safety of NPPs; urges the Commission, therefore, to include the overall r ...[+++]obustness of NPPs (in particular with regard to possible cracks in pressure vessels) as a specific criterion in future stress tests;

In hydrogen components that are subjected to frequent load cycles, conditions that can lead to local fatigue and the initiation and propagation of fatigue cracks in the structure must be avoided.
