The Wind Variability of Fall-Out Patterns

Description: The following report investigates part of the variability of the computed fall-out intensity patterns due to the variability of the winds, on the basis of winds from four Pacific shot days. An extreme case from Operation Sandstone is also considered.

A Survey of Some Los Alamos County Canyons for Radioactive Contamination, Spring 1953 to Spring 1955

Description: Abstract: This document is a survey analysis of soil samples from Los Alamos, Pueblo, Bayo, and Mortandad canyons to determine the presence and activities of radioactive contaminants. Also included are the results of analyses of a few samples of grass and of surface water. This survey covers the period from spring 1953 to spring 1955.

Magnetic Field Distributions in a Pinched Discharge

Description: By use of small magnetic probes inserted into the discharge, the magnetic field distributions in the interior of a high-power pinched discharge have been measured as a function of time. From these data the current distributions can be deduced. By applying a static pressure calculation, in the cases when the radical pinch accelerations are small, the plasma pressure nkT in the pinch has been determined, with superimposed axial magnetic fields, and for stable and unstable configurations.

Nonweapons Activities at Los Alamos Scientific Laboratory. Part III: Power Reactor Experiments

Description: The work of the Laboratory has greatly expanded into applications of nuclear energy which are significant for national defense and security, but are not directly connected with weapons development. It was felt, therefore, that a description of the non weapons activities of the Laboratory would serve a useful purpose at this time. For classification reasons, it has been necessary to issue the report in three parts; the third part concerns power reactor experiments.

Critical Assembly of Uranium Metal at an Average U236 Concentration of 16-1/4%

Description: A uranium metal critical assembly consisted of a 15 inch diameter core with an average U235 content of 16-1/4%, surrounded by a 3 inch thick natural uranium reflector. The critical mass was 692 kg of core material.

Nonweapons Activities at Los Alamos Scientific Laboratory. Part 1: Controlled Thermonuclear Reactions

Description: The work of the Laboratory has expanded into applications of nuclear energy which are significant for natural defense and security, but are not directly connected with weapons development. It was felt, therefore, that a description of the nonweapons activities of the Laboratory would serve a useful purpose at this time.. For classification reasons, it has been necessary to issue the report in three parts; this is the first and is concerned with controlled thermonuclear reactions.

Fabrication Procedure For RaLa Source Fuel Rods

Description: A new method to procure RaLa sources was proposed by Group CMR-10, Los Alamos Scientific Laboratory. This method depended upon irradiation of small-diameter U235 wire in the Materials Testing Reactor, Arco, Idaho. A procedure for cladding and sealing U235 wire in stainless steel tubing, by drawing, plugging the tube ends, and welding, was developed, tested, and proved to be satisfactory.

Time Behavior of Godiva Through Prompt Critical

Description: The transition region between short, but controlled, pile periods and uncontrolled, highly-supercritical conditions has been investigated with an unreflected, spherical uranium assembly (Godiva). This study was undertaken because knowledge of the behavior of supercritical systems is important in evaluation of reactor hazards and also the hazards of less standard operations involving possibly critical quantities of active material.

Process Development Studies for Recovering Ba140 From Irradiated Enriched-Uranium Rods

Description: As an alternative to recovering Ba140 from the spent MTR fuel assemblies a new enriched-uranium fuel pin was designed for irradiation. Two specimens, each containing about 3 g. of uranium (93% enriched), were irradiated to 1.3% and about 18% burnup. Examination after irradiation indicated that design improvements were needed; photographs are presented to illustrate the damage incurred during irradiation. A simple inorganic chemical process using precipitation and filtration techniques was devel… more

Some Experiments on the Precipitation of Plutonium Compounds From Triputyl Phosphate Solutions

Description: The experiments described in this report were designed to explore the feasibility of precipitating plutonium from 35 percent TBP in Gulf BT using peroxide, fluoride, sulfide, sulfite, sulfate, cocalate, hydroxide, iodate and phosphate ions from anhydrous, dilute and concentrated aqueous sources.

Determination of Ruthenium in Plutonium

Description: An analytical procedure for 0.04 to 1.6 percent ruthenium in plutonium metal was developed. Determination of ruthenium in metallic plutonium was investigated as part of a program for securing analytical procedures for various metals in plutonium. However, results of the investigation are given in this report with emphasis on the determination of ruthenium in plutonium chloride solutions. Specifically, this report is primarily concerned with the separation and determination of 40 to 400 microgra… more

Preliminary Survey of Uranium Metal Exponential Columns

Description: Reflected cylindrical exponential columns of bare and natural uranium were constructed of stacked plates of oralloy (93.4%) and tuballoy. Average concentrations of U235 ranging from 0,72% to 9.18% were investigated. Flux distributions, buckling values, and spectral indices were obtained. The indicated U235 concentration for infinite critical mass is about 5.5%.
