Abstract

An ITER hard core component (HCC) is defined for each undesirable situation with cliff edge effect consequences. Such structure system components (SCCs) are designed to prevent these situations at nuclear power plants, as well as to return and maintain a safe state in the event such a situation occurs. Only two hard core situations can really lead to cliff edge effect unless HCCs are implemented to limit the consequences: extreme earthquake (SL-3) and multiples fire in tritium building initiated by SL-3. The equipment (window and/or shutter) that closes penetrations from both sides of gallery to outside (Diagnostic building, Tritium building, and Assembly building) are classified as HCCs and SIC-2. Design status of the HCC penetrations belong to US ITER diagnostic systems will be presented in this publication.
