From abstract; "Two basic instruments were developed for determining the concentration of uranium in solutions. Both instruments detect the gamma activity present in a sample solution, and interpret this analysis into direct presentation as parts per million."

The reports aims to determine the solubility limitation of concentrations of uranium in the food preparation step of the tributyl phosphate waste metal recovery process, and the subsequent solubilities in the RA column.

This report covers the laboratory and pilot plant investigation of the reclamation of the low hafnium zirconium fines resulting from the manufacture of zirconium sponge and zirconium crystal bar. The process investigated involved recovery of the zirconium as zirconium tetrachloride, by drying the fines in an atmosphere of nitrogen and subsequent chlorination of the fines with anhydrous hydrogen chloride at temperatures above the sublimation point of the product.

The following report focuses on research made to determine whether the service performance of UO₂ fuel-elements cores for the PWR can be improved by certain ceramic or metal additions.

Report discussing tests to determine the aerodynamic characteristics of a model of a 45 degree swept-wing fighter airplane and to determine the loads on attached stores and detached missiles. An investigation into aileron-spoiler effectiveness, aileron hinge moments, and the effects of wing modifications of aerodynamic characteristics was also carried out at various Mach numbers. Results are presented, but caution is provided in regards to extrapolating results from the model onto a full-scale aircraft.

From introduction: "The present paper deals with a classical calculation in which some of the meson effects can be included to all orders in the meson-nucleon coupling coupling constant, in particular those having to do with the gyration of the nucleon spin and isotopic spin. Such a treatment leads to results qualitatively different from the weak coupling calculations."

Abstract: "The results of the investigation of three methods of obtaining transverse stability in linear accelerators for ions are presented and discussed. For electric or magnetic quadrupole focusing the range of stable operation, oscillation amplitudes, and the operation of an actual grid is analyzed from measurements of the field distribution. Finally, the formulas applicable to focusing by axial magnetic lenses are presented."

Report discussing the properties of a plasma held in a steady state by a magnetic field. Properties such as "electric and magnetic fields, current density, particle density, and macroscopic velocity" are determined analytically by assuming uniform temperature throughout the plasma.

Introduction: A proposal for using an energetic neutral deuteron beam for injection into a mirror machine has been made by Eugene Lauer. This report describes an experimental attempt to produce a large neutral deuteron beam. The beam from the NTA ion source was passed through a target of hydrogen gas where the charge exchange mechanics produced a beam of energetic neutral deuterium atoms.

From abstract: " This report describes the construction of a plasma source that projects deuterium and titanium ions and eletrons at speeds up to 2 x 10^7 cm/sec."

From abstract: "The reactivity effects of one and of two highly enriched fuel rods placed into a natural uranium lattice thermal pile are investigated according to the small source model."

Abstract: "The deuterium plasma which is ejected by a 6000-ampere pulsed current through a rail-type spark source has a yield in the forward direction which is a factor of 5 to 10 greater than that in the perpendicular direction. This effect is believed to be due to the magnetic propulsion of the plasma."

Abstract: An investigation of ionization by shock waves in hydrogen has been initiated. The shock waves are produced in a 1-inch diameter glass pipe by a high-voltage spark at one end. Variables which will influence attainment of the maximum degree of ionization and ion temperature are described. Spectroscopic methods of measuring ion density and temperature are outlined, and improvements in the design of the shock tube are discussed.

Report discussing waste line methods for separation plants at Hanford Works. A discussion of existing and proposed methods, including methods of protection for lines are included.

Thesis discussing the study of deuterons produced at wide angles to a beam of 300 Mev neutrons and a beam of 300 Mev protons. It was observed that the deuterons are formed by "a two step process in which the incident nucleon, or its collision partner, is scattered and then picks up in the same nucleus." Some tritons are also observed, and it is thought that they are formed by the same process as the deuterons. From these findings, the author concludes that "for heavy nuclei, there is a nuclear skin rich in neutrons."

Abstract: Mesas 1 1/2 and II 1/2 were investigated in October 1951, to determine the extent and degree of uranium mineralization in the Salt Wash sandstone. Carnotite-vanoxite-type minerals are sufficiently concentrated to recommend 14,600 feet of drilling.

The Technical Data Book compiles useful chemical and physical data of feed materials, chemicals, uranium intermediates and end products of the FMPC, Fernald, Ohio. The data presented encompass the process operations involved in the original integrated FMPC project, the uranium hexafluoride reduction plant and the throium plant.

Abstract: "A simple detector for determining the presence of UF6 in a stream of HF, UF4, and dissociated NH3 is described. The basic detection element is a sensitized piece of carbon rod. The unit has proved satisfactory on production equipment."

Abstract: "Since the first report on the use of amines as uranium extractants (ORNL-1734) over eighty additional organo-nitrogen compounds have been examined for their ability to extract uranium from aqueous solutions, particularly sulfate solutions, of the types usually encountered in uranium ore processing. As before, the more promising of these (as well as other compounds previously reported) have been examined further with respect to other characteristics essential to practical application, i.e., reagent loss to the aqueous phase, compatibility with practicable diluents, influence of commonly present anions, reagent stability, sufficient selectivity for uranium, adequate phase separation properties, compatibility with practicable stripping methods, etc. The potential cost and availability of the reagents tested, i.e., certain secondary and tertiary amines, have shown even greater promise as practicable extraction agents than many of the promising compounds previously tested. In addition to the work with sulfate liquors, cursory studies have been made of uranium extraction from fluoride and sulfate-fluoride solutions. Extractions of other metals from sulfate liquors, i.e., titanium and thorium, have been briefly examined."

Report presenting an investigation of the flutter characteristics of a series of thin cantilever wings with taper ratios of 0.6 for a range of Mach numbers. Results regarding flutter frequencies, time histories, effects of sweep on the flutter-speed ratio, effects of aspect ratio on the flutter-speed ratio, effects of additional models on the reference flutter speed, application of the flutter-speed ratio, and modified experimental flutter-speed coefficient are provided.

Local heat-transfer coefficients, temperature recovery factors, and pressure distributions were measured on the front side of a circular cylinder at a nominal Mach number of 3.9 over a range of free-stream Reynolds numbers from 2.1 x 10 to the 3rd power to 6.7 x 10 to the 3rd power and yaw angles from zero degrees to 44 degrees. Yawing the cylinder reduced the heat-transfer coefficients and the pressure drag coefficients. The amount of reduction may be predicted by a theory presented herein.
