Scope

1.1 This practice covers the dissolution of UF ₆ from a P-10 tube to provide solutions for analysis.

1.2 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. For specific safeguard and safety precaution statements, see Section 8.

Significance and Use

Uranium hexafluoride is a basic material used to prepare nuclear reactor fuel. To be suitable for this purpose the material must meet criteria for uranium content, isotopic composition, metallic impurities, hydrocarbon, and partially substituted halohydrocarbon content in Specification C 787. This practice results in the complete dissolution of the sample for uranium and impurities analysis, and determination of isotopic distribution by thermal ionization mass spectrometry as described in Test Methods C 761. Highly volatile impurities should be determined directly on UF₆.
