Scope

1.1 This test method is applicable to the isotopic analysis of uranium hexafluoride (UF₆) with ²³⁵U concentrations less than or equal to 5 % and ²³⁴U, ²³⁶U concentrations of 0.0002 to 0.1 %.

1.2 This test method may be applicable to the analysis of the entire range of ²³⁵U isotopic compositions providing that adequate Certified Reference Materials (CRMs or traceable standards) are available.

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 health practices and determine the applicability of regulatory limitations prior to use.

Significance and Use

Uranium hexafluoride is a basic material used to produce nuclear reactor fuel. To be suitable for this purpose, the material must meet criteria for isotopic composition. This test method is designed to determine whether the material meets the requirements described in Specifications C787 and C996.
