Flowsheet No. 1: Cesium isolation and packaging

Description: An engineering flowsheet has been prepared for the conversion of an aqueous slurry of cesium-zinc-ferrocyanide into a dry cesium chloride product by the calcination process. Flowsheet No. 1 defines a six-step batch-type calcination operation for processing the slurry into a dry powder for offsite shipment in bulk containers. Some of the advantages to this process are as follows: Product losses are expected to be small, estimated to be less than 0.03 percent; the equipment required to process a … more

Shock-Tube Experiments at University of Oklahoma and Cornell University

Description: Abstract: "The shock-tube experiments of Professor R. G. Fowler and his co-workers at the University of Oklahoma, and of Professor Arthur Kantrowits and his group at Cornell University, are reported by the author, who visited the laboratories of the two groups.

Investigation of Ejection Releases of an MB-1 Rocket From a 0.04956-Scaled Model of the Convair F-106A Airplane at Mach Number 1.59

Description: Report presenting an investigation of the ejection release characteristics of the MB-1 rocket from the missile bay of a model of the Convair F-106A airplane with its fin tips retracted at a simulated altitude of 18,670 feet. Successful ejections of the rocket were made at supersonic speeds by applying a combination of ejection velocity and nose-down pitching moment at release.

Separation plant effluent gas measurements for determining plutonium production rate

Description: The use of ion chambers or proportional beta counters is recommended for the measurement of Kr{sup 85} in separations plant gaseous effluent. It will be necessary to evaluate the Xe{sup 133} present if short cooling times (less than about 90 days) since irradiation are used. This can be accomplished through calibration and decay measurements. It is concluded that the Kr{sup 85} evolution could be determined to about {plus_minus}5% with careful measurements.
