Standard Practice for Sampling of Gaseous Uranium Hexafluoride for Enrichment

Importancia y uso:

5.1 Uranium hexafluoride is normally produced and handled in large (typically 1 to 14-ton) quantities and must, therefore, be characterized by reference to representative samples (see ISO 7195). The samples are used to determine compliance with the applicable commercial specification C787. The quantities involved, physical properties, chemical reactivity, and hazardous nature of UF₆ are such that for representative sampling, specially designed equipment must be used and operated in accordance with the most carefully controlled and stringent procedures. This practice can be used by UF₆ converters to review the effectiveness of existing procedures or as a guide to the design of equipment and procedures for future use.

5.2 The intention of this practice is to avoid liquid UF₆ sampling once the cylinder has been filled. For safety reasons, manipulation of large quantities of liquid UF₆ should be avoided when possible.

5.3 It is emphasized that this practice is not meant to address conventional or nuclear criticality safety issues.
