Recovery of Tuballoy (Uranium) From Tantalum

Description: Report discussing methods for the "separation of tantalum and tuballoy from used tantalum K's. These methods are: hydrofluorination, fluorination, hydrochlorination and dissolution in hydrofluoric acid -- nitric acid, hydrofluoric acid -- hydrochloric acid mixture, and hydrofluoric acid alone."

Recovery of uranium and plutonium from Redox off-standard aqueous waste streams

Description: In the operation of countercurrent extraction columns as in the Redox process, it is possible, and probable, that from unexpected behaviour of a column, operator error, colloid formation, etc., there will result from time to time excessive losses of uranium and plutonium in the overall process. These losses will naturally accumulate in the waste streams, particularly in the aqueous waste streams. If the loss is excessively high, and such lost material can be recovered by some additional method,… more

Recovery of Uranium From Beta Salvage Residues by Vapor Phase Chlorination With CCl₄

Description: Abstract: A simple process to recover the bulk of the uranium from ignited beta salvage residues was sought. In preliminary experiments a vapor phase chlorination with CCl₄ for about four hours followed by water and nitric acid leaching was found adequate. Recoveries are estimated at 60 to 90% of the total uranium content.

Recovery of Uranium From Contaminated Precipitron Oil

Description: Abstract: The distillation and residue extraction recovery procedures developed for the recovery of uranium from Kinney and diffusion pump oil, were applied to contaminated precipitron oil. The effectiveness and advisability of using the method, in whole or in part, is discussed, and various recommendations for processing this particular type of oil are presented. Additional contaminating substances present in this type of oil added to the complexity of the problem but a satisfactory recovery p… more

Recovery of Uranium From Fiberglass Air Filters

Description: Abstract: Various procedures for extracting uranium from fiberglass air filters have been tested and compared. Satisfactory results which involve the least amount of handling are obtained by simply washing the material with hot 1:1 hydrochloric acid.

Recovery of Uranium From Oil Distillation Residue

Description: Abstract: The complete development of an effective process for recovery of the uranium in the residues from distillation of used Kinney and diffusion pump oils or similar oils is described. After considerable study and experimentation with several methods, a successful procedure has been developed. The recommended procedure embodies solution of the residues in trichlorethylene followed by extraction with nitric acid. Recovery of uranium is better than 99 percent effective and the method may be … more

Rectangular Shell Plating Under Uniformly Distributed Hydrostatic Pressure

Description: "A check of the calculation methods used by Foppl and Henky for investigating the reliability of shell plating under hydrostatic pressure has proved that the formulas yield practical results within the elastic range of the material. Foppl's approximate calculation leaves one on the safe side. It further was found on the basis of the marked ductility of the shell plating under tensile stress that the strength is from 50 to 100 percent higher in the elastic range than expected by either method" (… more

Redox Committee: Conference notes and recommendations, April 5, 1949

Description: The notes and recommendations contained in this report relate to the design and construction of the Redox Production Plant with its associated Tank Farm at Hanford. All current development work for the Redox Program was to be transferred to the Redox Production Plant. [The Redox plant used a reduction-oxidation process for fuel separation that allowed recovery of uranium as well as plutonium for the first time. It succeeded earlier plants (T and B) that used methods based on the bismuth phospha… more
