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."

Report issued by the Bureau of Mines over manganese deposits of Santa Clara and Stanislaus Counties. As stated in the introduction, "the geology is outlined, ore deposits are described and work performed by the Bureau of Mines is covered in detail and supplemented by assay maps and figures" (p. 1). This report includes tables, maps, and illustrations.

This document is an addendum to DC 56-8-167 and gives a description of the proposed Navy nuclear seaplane program and the objectives of the X211 engine study program.

Report discussing the progress of research projects at Battelle Memorial Institute relating to civilian applications during August 1956.

Memorandum presenting an altitude investigation to determine the basic mechanism by which J65-W-4 turbine rotor-blade failures were occurring in service. The engine was installed in an altitude test chamber and a series of controlled engine throttle bursts, with and without inlet-air distortion, over a range of altitudes, flight Mach numbers, and inlet-air temperatures. An examination of the data obtained during the investigation indicated that the danger of turbine failure could be eliminated without any appreciable sacrifice in engine acceleration time.

From abstract: "The stability constants of curium and americium alpha hydroxyisobutyrate complexes were determined by means of ion exchange equilibrium measurements on Dowex-50 four percent resin in the ammonium form."

Abstract: "A particularly conventional modified form of Maxwell distribution is chosen. The modified expressions for (a) the energy transfer from the ions to the electrons in a plasma and (b) the brehmestrahlung from the electrons are calculated. Using the expressions some possible steady-state conditions for the ion and electron gases are derived and compared with those for the usual Maxwell distributions."

Abstract: "The quantities of interest in a confined plasma include the electric and magnetic fields, current density, diffusion velocity, temperature, pressure, and particle density. Equations governing the distribution of these seven variables are given in this report and special cases of a one-dimensional steady-state plasma are examined in detail. The solutions are given in graphical form."

Report discussing the heating of a plasma which passes through a series of magnetic pumping cells by applying the second-order theory of transit-time heating developed by Berger and Newcomb. From abstract: "Transit-time magnetic pumping in single-transit systems seems to be a feasible method of increasing plasma energy by amounts of the order of a factor of 10."

Report discussing the survey work done at the Battelle Memorial Institute with the objective to successfully build a gas-cooled reactor.

The Savannah River reactors were operated initially for the production of plutonium, and used slug-type natural uranium fuel elements. Recently one reactor was converted to the production of tritium, and other reactors will be converted soon. slug-type elements (of enriched uranium-aluminum) were charged into this reactor in order to reduce to a minimum the development effort required before the shift to tritium was made. It was recognized, however, that the slug elements would be deficient in that they would give a low yield of tritium per atom of uranium-235 destroyed because of the large parasitic capture of neutrons by aluminum. Also the production rate of tritium would be low because of the small amount of surface available for the transfer of the fission heat. Both of these shortcomings will be reduced materially by the substitution of tubular elements for the slugs now employed. The development of this type of element has progressed so that a full reactor loading of tubular fuel elements is contemplated for early 1957. The special hazards related to the production of tritium using tubular fuel elements are described in this memorandum which has been written as a supplement to a report entitled ``Reactor Safety Determination -- …

Abstract: The Diamond Head droup area is entirely igneous. Tight fractures in alaskite and granite, which have been altered by heiratite and kaolinization contain narrow seams and very locally,pods of sooty uraninite. A greater percentage of the structures in the area strike about east-west and dip steeply to the north, while the radioactive structures have similar strike, they dip steeply to both the north and the south. A drift has been driven on a mineralized structure far enough to ascertain that the general character of the mineralization is very narrow seams. Many such seams exists but are scattered throughout the area.

Corrosion of anode assembly materials in fluorine generators is pronounced, therefore, selection of the proper materials for construction is important. Several metals and alloys have been tested for corrosion resistance when anodic in a fluorine test cell. In general, copper, copper alloys and magnesium alloys offer the best corrosion resistance.

This document presents a summary of work and progress at the Hanford Engineer Works for August 1956. The report is divided into sections by department. A plant wide general summary is included at the beginning of the report, after which the departmental summaries begin. The Manufacturing Department reports plant statistics, and summaries for the Metal Preparation, Reactor and Separation sections. The Engineering Department`s section summarizes work for the Technical, Design, and Project Sections. Costs for the various departments are presented in the Financial Department`s summary. The Medical, Radiological Sciences, Utilities and General Sciences, Employee and Public Relations, and Community Real Estate and Services departments have sections presenting their monthly statistics, work, progress, and summaries.

Progress is reported in the fabrication and inspection of metals.

This bibliography contains 145 references on the technology and apparatus used in the purification of argon, helium and xenon, and on the analysis for water, carbon monoxide, hydrogen, nitrogen, and oxygen, in the purification process. The references are arranged in four classifications: general, argon, helium, and xenon. Within each classification, the references are arranged in chronological order.
