Grain Refinement of the As-Cast Uranium-5 w/o Chromium Alloy by Heat Treatment (open access)

Grain Refinement of the As-Cast Uranium-5 w/o Chromium Alloy by Heat Treatment

Introduction: "The uranium-5 w/o chromium alloy has been intensively investigated for use in a power reactor in the as-cast condition. However, when cast sample fuel elements were subjected to irradiation, their stability was found to be unsatisfactory. In order to improve the behavior of the alloy, a program of grain refinement by heat treatment was begun. The effect of chill casting on the heat-treated grain size was also investigated."

Applied Potential Corrosion of Aluminum and 18-8 Stainless Steel Alloys (open access)

Applied Potential Corrosion of Aluminum and 18-8 Stainless Steel Alloys

Introduction: In anticipation of the design of equipment for heat transfer tests, a series of short exposure corrosion tests was initiated in an effort to determine the order of magnitude of the corrosion involved. Information was required on the effect on corrosion rates of applying a potential between two concentric tubes, the annulus between them containing condensate water.

The Hydrolysis of Tributyl Phosphate Ad Its Effect on the Purex Process (open access)

The Hydrolysis of Tributyl Phosphate Ad Its Effect on the Purex Process

From abstract: "The rate of hydrolysis of TBP and the effect of the hydrolysis products in the Purex Process have been studied. Hydrolytic conditions may be encountered in the process which would lead to formation of dibutyl phosphoric acid, causing significant losses of tetravalent plutonium in stripping. This situation may be easily alleviated by reducing and stripping the plutonium in the trivalent state."

Relative Yields of Nitrogen-17 Produced by 190-Mev Deuteron Bombardment (open access)

Relative Yields of Nitrogen-17 Produced by 190-Mev Deuteron Bombardment

"Yields of N¹⁷ relative to that produced in LiF have been measured in the 190-Mev deflected deuteron and the 380-Mev alpha beams of the 184-inch synchrocyclotron. The measurements have been performed in all the light elements from 0 through V, with the exception of Sc and the noble gases. In addition, yields were measured in the separated isotopes of Mg...Comparisons are made with other types of yield studies performed with neutrons and protons, and the areas of agreement are noted."

Reconnaissance of Red Rock Valley, Apache County, Arizona (open access)

Reconnaissance of Red Rock Valley, Apache County, Arizona

Abstract: Reconnaissance of Red Rock Valley was begun on December 10, 1953, and completed on February 11, 1954. The mines in the region were investigated and all exposures of Salt Wash were walked. Paleostream directions and alterations of the sandstones were observed and recorded on a base map. No important new mineralization was discovered-and the area is considered to be of no commercial significance if judged by the outcrops alone. However, a vast amount of Salt Wash lies at slight depth directly to the east of the investigated area.

Uranium-Copper Deposits Near Copper Canyon Navajo Indian Reservation, Arizona (open access)

Uranium-Copper Deposits Near Copper Canyon Navajo Indian Reservation, Arizona

From introduction: During the summer of 1951, Navajos conducted John W. Chester, Russell C. Cutter, and E. V. Reinhardt, Grand Junction Exploration Branch, U. S. Atomic Energy Commission, to a copper deposit in Copper Canyon. Little radioactivity was noted, and no further work was done in the area at that time. In October 1951, the same group of Navajos reported the discovery of uranium ore in another portion of the same area. The site was visited by Cutter who noted that an excavation made by the Navajos had disclosed a 3-foot thickness of low-grade uranium ore. In November 1951, Cutter again visited the area and observed that the Navajos had opened a 5-foot face of good ore.

Geologic and Radiometric Reconnaissance Along the San Juan and Colorado Rivers Between Mexican Hat, Utah, and Lees Ferry Arizona (open access)

Geologic and Radiometric Reconnaissance Along the San Juan and Colorado Rivers Between Mexican Hat, Utah, and Lees Ferry Arizona

Abstract: Ten days were spent during June 1955, examining the sedimentary rocks along the San Juan and Colorado Rivers between Mexican Hat, Utah, and Lee's Ferry, Arizona. The most favorable area for uranium deposits occurs in the Shinarump member of the Chinle formation between Clay Hills Crossing and Spencer Camp along the San Juan River. Mineralization is spotty and deposits are small and almost all below ore-grade. Only one small mine, the Whirlwind, is currently producing ore. Gray-green alteration of the underlying Moenkopi is moderately developed in the vicinity of the Whirlwind mine; elsewhere alteration is weakly developed.
