Essential technical requirements for mechanical components and metallic structures foreseen for Generation IV nuclear reactors (ISO 18229:2018)
ISO 18229:2018 defines the essential technical requirements that are addressed in the process of design and construction of Generation IV (GEN IV) nuclear reactors. It does not address operation, maintenance and in-service inspection of reactors.
Six reactor concepts are considered for GEN IV: the sodium fast reactor, the lead fast reactor, the gas fast reactor, the very high temperature reactor, the supercritical water reactor and the molten salt reactor.
Annex A details the main characteristics for the different concepts.
The scope of application of this document is limited to mechanical components related to nuclear safety and to the prevention of the release of radioactive materials
? that are considered to be important in terms of nuclear safety and operability,
? that play a role in ensuring leaktightness, partitioning, guiding, securing and supporting, and
? that contain and/or are in contact with fluids (such as vessels, pumps, valves, pipes, bellows, box structures, heat exchangers, handling and driving mechanisms).
Grundsätzliche technische Anforderungen an mechanische Komponenten und metallische Strukturen vorgesehen für Kernkraftwerke der Generation IV (ISO 18229:2018)
Exigences techniques essentielles pour les composants mécaniques et les structures métalliques destinés aux réacteurs nucléaires de quatrième génération (ISO 18229:2018)
Le présent document définit les exigences techniques essentielles qui sont traitées lors du processus de conception et de construction des réacteurs nucléaires de quatrième génération («GEN IV»). Il ne couvre ni l'exploitation, ni la maintenance, ni l'inspection en service des réacteurs.
La quatrième génération couvre six concepts de réacteurs: les réacteurs à neutrons rapides à caloporteur sodium, les réacteurs à neutrons rapides à caloporteur plomb, les réacteurs à neutrons rapides à caloporteur gaz, les réacteurs à très haute température, les réacteurs à eau supercritique et les réacteurs à sels fondus.
L'Annexe A décrit les principales caractéristiques des différents concepts.
Le domaine d'application du présent document se limite aux composants mécaniques en lien avec la sûreté nucléaire et la prévention de l'émission de matières radioactives:
— qui sont jugés importants sur le plan de la sûreté ou de la disponibilité;
— qui ont une fonction d'étanchéité, de cloisonnement, de guidage, de maintien ou de supportage;
— qui contiennent et/ou sont en contact avec des fluides (par exemple récipients, pompes, robinets-vannes, tuyauteries, soufflets, structures caissonnées, échangeurs et mécanismes de contrôle et de manutention).
