Uranium Hexafluoride in Pressurized Cylinders

The primary sample bottle is transferred to the operator s laboratory and mounted on a subsampling station O Fig. 63.10). The UFg is liquefied and a subsample of 1 to 5 g is collected again from the liquid phase (ANSI 1972 ISO 1996b) into a finger tube ( Fig. 63.11), which is weighed and shipped to the inspectorate laboratory. If the subsample is not issued from homogeneous liquid phases, only the uranium isotopic analysis will provide a meaningful result. In such a case, it is recommended to skip the elemental uranium assay.
