Correlation of Exponential and PCTR Measurements of Cluster Fuel Elements with Theory

Description: Accurate knowledge of the lattice parameters comprised in the four factor formula k∞=η∈Pi are required for optimum designing of reactors. In the special case of cluster fuel elements conventional handbook formulas are of little use. It is the intent of this paper to report the results of some recent improvements in the calculation of these parameters. By the addition of certain refinements in the calculation of these parameters. By the addition of certain refinements to the conventional calcula… more

Fluorescent X-Ray Spectrography- A Recent Analytical Technique

Description: Because of the relative simplicity of the X-Ray spectra and recent improvements in instrumentation, analytical applications of X-Ray of spectrography are becoming very popular. The method us applicable to both qualitative and quantitative determinations of all elements heavier than sodium. Elements in multicomponent systems, such as alloys and minerals, and elements such as, W, Pt, Nb, Ta, Hf, Zr, and the rare earths, which are difficult to separate or determine by other methods, can usually be… more

Computer description APPR-1 simulator

Description: The APPR-1 is a pressurized water reactor having a low specific heat fuel and a water primary coolant. The primary coolant loop delivers heat from the reactor to the steam generator. The secondary water in the steam generator is converted to steam and then taken to the turbine to drive an electrical generator. The simulation of this system is broken down into three primary areas: the neutron kinetics in the reactor which are necessary to generate the primary power function, the heat transfer… more

Standard Practices Guide for Writing Experimental Operating Manuals

Description: This is a sample operating manual designed to aid experimenters in writing operating manuals for MTR and ETR experiments. It contains what is felt to be the necessary information for operating a particular experiment. One of the main functions of an operating manual is to provide quick reference to material needed in an emergency. It is believed this type of manual provides the required information without an excessive amount of bulky, surplus material.

The Fabrication of a Plutonium Helix for a Doppler Experiment

Description: A helix constructed of plutonium was made to test the Doppler temperature effect in ZPR-III. The helix, 1 inch in diameter and 6-1/4 inches long, contained 240 grams of delta-phase plutonium alloy encapsulated in titanium tubing. Four plutonium rods were extruded, joined together, and pushed into a titanium tube. This tube was swaged tightly over the plutonium rod, and the assembly was wound into a coil. Electrical leads to the coil were made by swaging copper tubing over the ends of the coil. … more

Investigation of Uranium Deposits, Anderson Mine and Adjacent Properties, Yavapai County, Arizona

Description: From abstract: A team consisting of R. A. Lindblom, S. A. Mayer, R. G. Young, W. L. Chenoweth, R. F. Droullard, and I. T. Fisk made a reexamination of the Anderson mine (Uranium Aire) of Interstate Oil and Development located near Wickenberg in Yavapai County, Arizona. The field examination was made from August 22, 1958 to September 2, 1958. This team was formed to resolve differences between company and AEC ore reserve estimates. A cooperative effort in which the company supplied labor, limite… more

Preliminary Results Obtained With Catalytic Surfaces in the Upper Atmosphere During Balloon Flights

Description: Abstract: Using high altitude balloons,preliminary investigation of recombination rates of atomic particles and free radicals was performed by exposing radiosonde thermistor elements specifically vacuum coated with silver and aluminum oxide. Positive results were obtained by the silver coated thermistor while the coated thermistors showed negative readings as was expected.

Pressure Balance in a Toroidal Pinch

Description: Abstract: In the study of a linear pinch, use of the equation of pressure balance has proven to be a powerful method of analyzing data taken with a magnetic probe. The toroidal pinch, however, is a geometrically more complicated object, and the use of the pressure balance equations is not so clean cut. It is the object of this note to analyze the pressure balance equations for a torus to the point where they might prove useful in interpreting probe data.

Radial distribution of plasma in Astron's E-layer

Description: A report discussing a more general analysis of "the relation between plasma pressure in the Astron [Thermonuclear Reactor] and the magnetic field of the E-layer" which is described in UCRL-5032. The analysis given in this report has "no restriction to the exponential form and [satisfies] the condition that the pressure at the axis shall be zero."
