The Machinability of Beryllium

Description: The following report investigates the isolation of the cause of the unusual tool-wear rates found in machining beryllium as attributed to an inherent characteristic of beryllium, or an effect of inclusions in beryllium, as well as the evaluation of the comparative machinability of the various types of beryllium.

The Preparation and Some Properties of a Uranium Hexafluoride-Sodium Fluoride Complex

Description: Report discussing "preparation of some stable complexes of uranium hexafluoride with sodium, potassium, and thallium fluorides...Such compounds, reported as stable in air and of low vapor pressure, offered promise as convenient sources of unoxygenated hexa-valent uranium without the difficulties associated with the use of uranium hexafluoride itself."

Polarographic Determination of Uranium in Dust Samples

Description: Abstract: "Samples of dust are collected from the atmosphere with a Mine Safety Appliance Co. electrostatic precipitator and analyzed for uranium by means of a dropping mercury electrode apparatus. Two to three micrograms of uranium can be detected in a cell solution volume of 1 ml. Iron, nickel and chromium present in shop dusts do not interfere. Copper may interfere if present in excess but may be removed by a sulfide precipitation. Directions for preparation of cell solution and operation of the Polarograph are given. The polarographic method described may be used for determination of uranium in samples other than atmospheric dusts."

The Engineering Properties of Iron-Limonite Concrete for Construction of Biological Shields

Description: Introduction: "This letter is intended to provide a brief summary of the information presently available on the engineering properties of iron-linonite concrete with the view of adapting such concrete with the view of adapting such concrete for use as biological shielding material in a Hanford pile. By reducing materials and fabrication costs, such a adaptation might effect a savings of at least two million dollars per pile over the present iron-masonite laminated shield structure."

Separation of Isotopes by Mass Diffusion - Unequal Diffusion Coefficients

Description: From summary: "Equations for determination of stage enrichment factor and screen area for the ideal case of 'zero back-pressure' are derived...Comparison with the theory of Benedict is made together with recommendations for application of his results for non-zero back pressure to the case under consideration."

Measurements of B₄C and H₂O Shield in the Lid Tank : Experiment 11

Description: The following report measures neutrons and gammas in solid B4C, as well as measuring H2O containing .5% boron by weight in the lid tank. Quantities measured in the following report in borated water are: thermal neutron distribution along the center line of the source (Z); fast neutron dose vs. Z; Gamma dose vs. Z; and neutron absorption by boron within solid B4C.

Optical Properties of Three Uranium Phosphates

Description: Abstract: "Crystal system, crystal habit, and principal refractive indices, of uranyl hydrogen phosphate tetrahydrate, uranyl ammonium phosphate trihydrate, and uranyl phosphate tetrahydrate are reported. A procedure for differentation of these three compounds using this data was developed."

The Kinetics of the Circulating-Fuel Nuclear Reactor

Description: Abstract: "In a circulating-fuel reactor, the circulation of the fuel cause a damping of power oscillations of the reactor. This is demonstrated under the assumption, that there is no mechanical vibration coupled with the oscillation of reactor power, and that the shapes of the hydrodynamic flow does not vary with time."
