Report issued by the Brookhaven National Laboratory discussing the shipboard cobalt-60 irradiator. As stated in the introduction, "this report discusses the conceptual design of a cobalt-60 shipboard irradiator for use to improve the keeping quality of fish landed aboard commercial fishing trawlers operating out of ports along the eastern seaboard of the commercial United States" (p. 1). This report includes tables, and illustrations.

Foreword: This report describes the results of a series of engineering evaluation studies conducted between July 1, 1961 and June 30, 1962, related to heavy water moderated power reactor plants.

From foreword: This report investigates the economics and performance of alternate cycles for heavy water moderated power reactors.

From introduction: This study is a comprehensive investigation of altered sandstone associated with uranium deposits near Pumpkin Buttes in the Powder River Basin of Wyoming, and the detection of such alteration using remote sensing technology. The purpose of this study is two-fold: 1) to develop video image processing techniques that will preferentially enhance areas of alteration associated with uranium deposits and enable mapping of these areas, and 2) to investigate the spectral, geochemical, and mineralogical characteristics of altered areas which make them detectable on remote sensor data. Once these video processing techniques have been defined, they may be applied as exploration tools to new areas with similar surface and geological environments. In this way, remote sensing can serve as a valuable tool for uranium exploration.

"A series of high urania-content glasses were fiberized and examined for high-temperature strength properties. One glass, RX360 containing 60% U/sub 3/O/ sub 8/ by weight, had better high-temperature tensile properties than any glass previously reported. It was observed that many of the glasses studied separated into immiscible phases and that the fiberizable glass phase had lower U/sub 3/O/ sub 8/ content than the base compositions. A physical analysis of crystal structures of the devitrification products from the nuclear fuel glasses indicated that most of the crystals consisted of uranium oxide in a reduced state. By adding O/sub 2/ to molten glass, it was possible to eliminate most of this devitrification. By elimination of crystals, the fiberizing of the glass was more uniform and the glasses produced had more consistent physical properties."

Abstract: A series of clean critical experiments was performed in the SGR critical facility utilizing 2 wt % enriched, uranium metal, hollow cylinder, fuel elements, in AGOT graphite moderator.

From abstract: Results of the Date Creek Basin detailed geochemical survey are reported. Field and laboratory data are reported for 239 stream sediment samples. Statistical and areal distributions of uranium and possible uranium-related variables are displayed. A generalized geologic map of the area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.

This report for June, 1947 describes progress regarding ore dressing and pyrometallurgical studies, chemical work, analytical work, and beta counting.

From Foreword: "The program described herein proposed the use of a traveling bridge crane with fixed position, totally enclosed cab, as a means for maintaining and repairing the canyon area of a chemical process plant handling highly radioactive solutions."

"Properly designed and fitted respirators have been effective devices for reducing the inhalation of toxic aerosols. The degree of protection afforded by these devices has not been quantitatively measured under actual work conditions except by bioassay or other elaborate techniques. This report describes a new quantitative technique for evaluating over-all respiratory performance under conditions comparable to exposure to highly toxic radioactive materials such as plutonium and non-radioactive materials such as beryllium."
