Hydration of uranium residues contained in enriched UF6 cylinders

Description
The transport of uranium hexafluoride (UF6) is carried out in large steel cylinders. During filling and extraction operations, some air in-leakage in cylinders is possible and its moisture content results in the hydrolysis of UF6 and the creation of non-volatile uranium residues, in particular UO2F2 complexes with H2O and HF. This paper presents justifications for considering, in criticality safety assessments of enriched UF6 transport cylinders, a bounding hydration ratio H/U of 6 for uranium residues, based on the operating conditions of UF6 cylinders in fuel facilities.
