Electrolytic procedure for the removal of ruthenium and nitrate from alkaline waste solutions

Description: The flowsheet proposed by KAPL for the treatment of alkaline nitrate radiochemical processing waste has been modified to include an ion-exchange step for the decontamination of cesium, strontium, and other cationic fission products. In laboratory studies of the electrolysis steps in a nitrate reduction cell, synthetic alkaline waste, 0.55 to 4.83 M total electrolyte, was decontaminated from ruthenium by factors of > 210. The nitrate of 3.0 M waste was reduced to ammonia with current efficien… more

Nitric acid recovery and ammonia removal: Modifications to the Redox dissolver off-gas systems

Description: Project CG-588 authorized the design and construction of dissolver and waste neutralizer off-gas scrubbers to remove the ammonia given off during coating removal and waste neutralization steps of the Redox operation. It has always been recognized that the nitrogen oxides in the dissolver off-gases, resulting from the dissolution of bare uranium slugs, could also be absorbed in water under proper conditions to give re-useable nitric acid. Consequently it appeared feasible to provide facilities w… more

Unusual incident at Savannah River

Description: On January 12, 1953, an explosion occurred in the Savannah River pilot plant which has been used since November, 1951 by du Pont personnel to train operators and to test equipment for their new Purex production plant. The explosion occurred in an evaporator in which a uranyl nitrate solution containing some organics was being concentrated to a high degree to remove nitric acid. This memorandum reviews the facts surrounding the incident as obtained from the official Preliminary Technical Report'… more

High-Frequency Titration as Applied to the Determination of Thorium, Uranium, Sulfate, and Free Acid. Parts 1-51

Description: The technique of high-frequency titrimetry was applied to the determination of thorium, uranium, sulfate, and free acid. In Part I, the reproducibility of the method for the titration of standard solutions that contained 50 rag of thorium in the absence of interferences is established. Under these conditions, the coefficient of variation of the method was <1%. In Part II, the effect of uranium on the highfrequency titration of thorium, as well as the application of the method to actual samples,… more

ISOTOPIC EQUILIBRIA OF NITROSYL CHLORIDE

Description: The electrolytic solvent characteristics of liquid nitrosyl chloride and general consideration of the factors affecting suitability of a system for isotope separation suggest that exchange reactions of NOCl might provide an interesting and useful means for the separation of the stable isotopes of nitrogen or of chlorine, or of both in a simultaneous process. Vibrational frequencies of isotope substituted NOCl molecules are calculated and used to estimate equilibrium constants for exchange of ni… more

Studies of the Behavior of the Tbp-Kerosene Solvent in Uranium Refining: Degradation of the Kerosene Diluent

Description: Extensive studies have been conducted of kerosenetype diluents for the tri-n-butyl phosphate (TBP)kerosene solvent used in uranium extraction. Wide variations have been shown in the paraffinic, isoparaffinics aromatics and olefinic hydrocarbon contents of these diluents. Such diluents have been shown to be unstable in thc presence of high nitric acid concentrations, and in the presence of small amounts of nitrous acid. This instability is primarily a function of the non-paraffinic hydrocarbon c… more

The Gravimetric Determination of Tungsten in Uranium-Tungsten Alloys

Description: Tungsten in uranium--tungsten alloys is determined by precipitating the tungsten from a cold sulfuric acid solution using alpha -benzoinoxime and cinchonine as the precipitating agents. The precipitate is dgnited at 800 deg C and weighed as WO/sub 3/. Results of 94 determinations on known samples containing 20 to 40 milligrams of tungsten in the presence of 1 to 8 grams of uranium showed an average recovery of 100.1% with a standard deviation of 0.7%.

SULFOCHLORINATION OF HYDROCARBONS INDUCED BY GAMMA RADIATION

Description: The purpose of this study was to determine the effect of gamma radiation on the direct sulfochlorination of hydrocarbons and nitrobenzene. The radiation source consisted of spent uranium fuel elements, providing a gamma radiation intensity up to 2.5 x 10/sup 6/ roentgen/ hour. The sulfochloriuation studies were carried out either with SO/sub 2/Cl/sub 2/ or with gaseous mixtures of SO/ sub 2/ aud Cl/sub 2/. Attempts to sulfuochlorinate nitrobenzene and benzene were unsuccessful. There was no det… more

THE OXIDATION OF MERCURY BY NITRIC ACID

Description: The oxidation of Hg in HNC/sub 3/ was investigated. An empirical rate law, oxidation rates, and Hg species in solution were determined. A reaction mechanism based on the presence of nitrous acid can be interpreted in terms of the rate expression derived. (auth)
