This specification covers fiber-reinforced carbon-carbon (C-C) composite components (flat plates and tubes) manufactured specifically for structural components in nuclear reactor core applications. The specification includes a classification system and requirements/ recommendations for physical and chemical properties, mechanical properties, performance durability, materials and fabrication processing, methods of testing, and quality assurance. The carbon-carbon composite classes specified here would be suitable for reactor core applications where neutron irradiation induced damage and dimensional changes are a significant design consideration. This specification is specifically focused on C-C composite components with a flat panel or a tubular geometry.
This classification and specification document is needed to provide clear guidance and direction on specifying, producing, and qualifying carbon-carbon composites for use as structural components in nuclear reactors. It will be used by producers, end-users, and regulatory agencies.
