- Summary
- Studies designed to characterize the reaction between UF/sub 6/ and atmospheric moisture, evaluate environmental variables of UF/sub 6/ cloud formation and ultimate cloud fate, and UF/sub 6/ release cloud control procedure have been conducted in the 1200 cu. ft. GAT environmental chamber. In earlier chamber experiments, 30 separate UF/sub 6/ release tests indicated that variations of atmospheric conditions and sample sizes had no significant effect on UO/sub 2/F/sub 2/ particle size distribution, release cloud formation, or cloud settling rates. During the past year, numerous procedures have been evaluated for accelerating UF/sub 6/ cloud knockdown in a series of 37 environmental chamber releases. Knockdown procedures included: coarse water spray; air jet; steam spray (electrostatically charged and uncharged); carbon dioxide; Freon-12; fine water mist (uncharged); boric acid mist (charged and uncharged); and an ionized dry air stream. UF/sub 6/ hydrolysis cloud settling rates monitored by a laser/powermeter densitometer, indicated the relative effectiveness of various cloud knockdown techniques. Electrostatically charged boric acid/water mist, and electrostatically ionized dry air were both found to be very effective, knocking down the UO/sub 2/F/sub 2/ release cloud particles in two to five minutes. Work to adapt these knockdown techniques for use under field conditions is continuing, taking into account recovery of the released uranium as well as nuclear criticality constraints.
