Engineering Study of Evaporation for Concentrating Radioactive Liquid Wastes : Engineering Research Final Report
Summary: "The problem of evaporation of secondary radioactive wastes resulting from waste disposal studies at Mound Laboratoy has been studied experimentally to determine the fundamental design characteristics of a plant size unit. Emphasis, of course, was on decontamination, but the factors affecting foaming and scaling also had to be investigated and evaluated. Generally speaking, the final design is a standard type of evaporator, the only unique feature being the relation of the two effects. Where critical, as affecting performance, the particular design features have been specified."

Reconnaissance Examinations of Copper Uranium Deposits West of the Colorado River
Several relatively small copper-uranium deposits have been found in southwestern Utah along the contact of the Shinarump and Moenkopi formations of Triassic age, at least from the San Rafael Swell area of Emery County, southward through central and eastern Garfield County, southwestward into western Kane County, and westward into the southern part of Washington County.

The crystal structure of thorium nitrate
From introduction: "Studies were made of single crystals of thorium nitrate hydrate which we had available in this laboratory and from these we were able to determine the unit cell and find the thorium positions. These crystals contain on the order of six water molecules per thorium atom, but the exact composition is in some doubt."

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

Preliminary Considerations Regarding Stability of MTA Mark I as a Closed-Loop System
The basic scheme under consideration in this research on stability of closed-loop of the Mark I machine is one in which a voltage proportional to the magnitude of the rf fields in the cavity acts to control rectifier voltage output. It is recognized that such is not the only scheme for maximization of output which may be conceived, but only what seems to be a logical and direct way of attaining such an objective.

Geology and Ore Deposits of Mesa V, Lukachukai District, Arizona
From abstract: Mesa V of the Lukachukai area is capped by Morrison sediments which dip gently eastward from the mountains to the mesa tip, where the strata are tilted sharply to the opposite dip by the Lukachukai monocline. The Salt Wash of Mesa V contains ore outcrops which indicate favorable intensity of mineralization at one horizon along a 2000-foot outcrop interval. Other scatted exposures indicate the existence of ore under much of the mesa surface.
