Water immersion tests of UF sub 6 cylinders with simulated damage
Abstract
A series of water immersion tests of UF{sub 6} cylinders with simulated damage was conducted to determine the extent of water inleakage. The uranium hexafluoride content was less than normal enrichment. Metal and glass cylinder units were used and metal-to- glass cylinder connections were also tested. In openings which occur where UF{sub 6} has solidified on the metal container walls or across the valve, an insoluble plug of monohydrated UO{sub 2}F{sub 2} and metallic products is formed. This results from the reaction of the UF{sub 6} and water and the reaction of the resultant HF with the metal. Water will enter a void area if UF{sub 6} is not immediately available for reaction. Similar plug formations do not occur in Laboratory tests using glass tubes. 4 tabs.

Technical bases for using vapor-phase sampling to determine the UF/sub 6/ content of cylinders of liquid UF/sub 6/-HF
This report describes a reanalysis of data on liquid-liquid and liquid-vapor equilibria in the system UF/sub 6/-HF, and the associated vapor pressures, and the applicability of these data to the use of analyses of vapor-phase samples for determining liquid-phase compositions; that is, determining the UF/sub 6/ content of the solution. Such use of vapor-phase sampling requires that: (1) UF/sub 6/ and HF be the only significant components present; (2) equilibrium between liquid and vapor phases exists during the sampling operation. The first specification does not mean the exclusion of tens of parts per million of nonvolatile corrosion products; instead, itmore »
