ASTM-D7219 › Standard Specification for Isotropic and Near-isotropic Nuclear Graphites
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
1.1 This specification covers the classification, processing, and properties of nuclear grade graphite billets with dimensions sufficient to meet the designer’s requirements for fuel elements, moderator or reflector blocks, in a high temperature gas cooled reactor. The graphite classes specified here would be suitable for reactor core applications where neutron irradiation induced dimensional changes are a significant design consideration.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. (See .)
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
