This specification covers nuclear grade uranium hexafluoride (UF6) that has been processed through an enrichment plant or produced by blending highly enriched uranium with other uranium to produce a concentration suitable for nuclear fuel fabrication. This specification defines the impurity and uranium isotope limits for the enriched commercial grade UF6 and for enriched reprocessed UF6. All materials should conform to the specified chemical, physical, and isotopic requirements.

1. Scope | ||||||||||||
1.1 This specification covers nuclear grade uranium hexafluoride (UF6) that either has been processed through an enrichment plant or has been produced by the blending of Highly Enriched Uranium with other uranium to obtain uranium of any 235U concentration below 5 % and that is intended for fuel fabrication. The objectives of this specification are twofold: 1.2 This specification is intended to provide the nuclear industry with a standard for enriched UF1.3 The scope of this specification does not comprehensively cover all provisions for preventing criticality accidents or requirements for health and safety or for shipping. Observance of this specification does not relieve the user of the obligation to conform to all applicable international, federal, state, and local regulations for processing, shipping, or in any other way using UF6 (see, for example, TID-7016, DP-532, and DOE O474.1). 1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
