Optimum Design of Catalytic Towers

Description: Abstract: "This paper gives an arithmetic method of computing the number of sections required in a catalytic tower to produce a given enrichment. It also tells how to calculate the enrichment of a tower with a given number of sections. The problem of the most economical design of catalytic towers is solved. Methods are given for determining the temperature, the efficiencies of catalyst beds and strippers, the relative production rate, and the water vapor-hydrogen gas ratio which give the optimu… more

Studies on the Electrolytic Reduction of Nitric Acid

Description: Report discussing the reduction of nitric acid that results from its use at the cathode for the electrolysis of uranyl nitrate. From introduction: "It is the purpose of this report to give the results of studies on the reduction of nitric acid of different concentrations, at different types of electrodes, and for various current densities in order to ascertain the effects of such changes."

Radiometric Analysis of Thick Samples

Description: Introduction: Measurements of polonium content in solids are usually performed by dissolving the material and preparing a thin sample which can be measured with one of the available instruments. A measurement of the radiation emerging from the thick sample should be sufficient to evaluate the polonium content. For this reason a calculation has been performed and the results have been compared with those obtained by the thin sample method. Obviously this proposed method using thick samples would… more

Healing of Fast-Neutron-Induced Changes in Graphite. III. Further Experiments on Effect of Heating During Exposure

Description: Abstract. It has been established that heating samples of graphite during exposure in a pile decreases substantially the observed changes in the elastic modulus and electrical resistance caused by the irradiation. The functional relationship between the percentage changes observed and the temperature of exposure resembles the relationship between the final percentage changes and the temperature of heat treatment after exposure (cf. report CC-1668). Anomalous results reported previously for hi… more

Factors Affecting the Precipitation of Tubanyl Peroxide from Gunk Solutions at Reduced Temperatures

Description: This paper reports work carried out to determine the factors necessary to give a filterable precipitation and determine the effects of these factors on the quantitativeness of the precipitation, and how any tendency to increase the tuballoy solubility may be overcome.

The Uranium-Cobalt System

Description: Abstract: "A phase diagram for the uranium-cobalt system has been constructed, based on thermal, microscopic, X-ray and chemical data. The results indicate the existence of three compounds and two eutectics, one of which shows a lowering of the melting point of uranium by approximately 400 C."

Analysis of X-ray Powder Diffraction Data on Crystalline Uranium Hexafluoride.

Description: From introduction: "The concluding remarks of the report on the electron diffraction study of UF6 suggest two alternate explanations for the apparent discrepancy between the structure proposed for this compound as deduced from X-ray diffraction work on single crystals and from the electron diffraction investigation of the vapor. The second explanation is based on the premise that the difference may be due to essentially unlike methods of treating the diffraction data. In this report we shall an… more

Mass Spectrometric Determination of Isotopic Ratio with Varying Ion Beam Intensity

Description: Summary: "An apparatus is described which applies alternate pulses from two ion beams to a galvanometer network. The isotopic ratio is read directly from a potentiometer. The comparison is independent of ion beam intensity. This method is not practical for application to the standard Nier assay instrument because of the low ion currents normally used. It is suggested that this comparison method may have utility in a spectrometer utilizing a high intensity ion source such as capillary ore or con… more

Reclamation of Contaminated Kinney and Diffusion Pump Oils and Removal of Uranium Therefrom

Description: Abstract: Test distillations were made with Kinney and diffusion pump oils under vacuum in order to determine accurately the temperature range over which satisfactory distillate may be collected. Also recommendations are made as to the most advisable type of heating equipment necessary to produce the required heat and maintain the desired temperature. In addition, several important refinements in the distillation equipment were checked for operational characteristics and for their efficiency in… more

The Maintenance of Animals Containing Radioactive Materials

Description: Abstract: In the Biology Division, the maintenance of animals containing radioactive materials posed many problems. In addition to routine care of the animals, protection had to be provided for the personnel who worked with the contaminated animals. Frequent air changed in the room in which the animals were caged were necessary: farm workers were required to wear masks; animal cages were checked regularly for radiation; acid was used on the sawdust in the excrete pens; and a new, more efficient… more
