Standard Guide for Development of Specifications for Fiber Reinforced Carbon-Carbon Composite Structures for Nuclear Applications
|Publication Date:||1 September 2015|
This document is a guide to preparing material specifications
for fiber reinforced carbon-carbon (C-C) composite structures (flat
plates, rectangular bars, round rods, and tubes) manufactured
specifically for structural components in nuclear reactor core
applications. The carbon-carbon composites consist of
carbon/graphite fibers (from PAN, pitch, or rayon precursors) in a
carbon/graphite matrix produced by liquid infiltration/pyrolys
This guide provides direction and guidance for the development of a material specification for a specific C-C composite component or product for nuclear reactor applications. The guide considers composite constituents and structure, physical and chemical properties, mechanical properties, thermal properties, performance durability, methods of testing, materials and fabrication processing, and quality assurance. The C-C composite materials considered here would be suitable for nuclear reactor core applications where neutron irradiation-induced damage and dimensional changes are a significant design consideration.

The component specification is to be developed by the
This guide is specifically focused on C-C composite components and structures with flat panel, solid rectangular bar, solid round rod, or tubular geometries.
This specification may also be applicable to C-C composites used for other structural applications discounting the nuclear-specific chemical purity and irradiation behavior factors.
