Description

1.1 This specification covers nuclear grade uranium hexafluoride (UF 6 ) 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 ²³⁵ U concentration below 5 % and that is intended for fuel fabrication. The objectives of this specification are twofold: (1) To define the impurity and uranium isotope limits for Enriched Commercial Grade UF 6 so that, with respect to fuel design and manufacture, it is essentially equivalent to enriched uranium made from natural UF 6 ; and (2) To define limits for Enriched Reprocessed UF 6 to be expected if Reprocessed UF 6 is to be enriched without dilution with Commercial Natural UF 6 . For such UF 6 , special provisions, not defined herein, may be needed to ensure fuel performance and to protect the work force, process equipment, and the environment.

1.2 This specification is intended to provide the nuclear industry with a standard for enriched UF 6 that is to be used in the production of sinterable UO 2 powder for fuel fabrication. In addition to this specification, the parties concerned may agree to other appropriate conditions.

1.3 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 UF 6 (see, for example, TID-7016, DP-532, ORNL-NUREG-CSD-6, and DOE O474.1).

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
