Geology of Part of the Craig C-2 Quadrangle and Adjoining Areas, Prince of Wales Island, Southeastern Alaska

Description: From abstract: The area mapped is on the east coast of Prince of Wales Island, southeastern Alaska, about 35 miles northwest of the town of Ketchikan. Deposits of magnetite and copper in the mapped area and on Kasaan Peninsula, which adjoins it on the southeast, have been mined for copper and have produced more than 600,000 tons of ore valued at more than $6 million.

Geology of the Craig Quadrangle, Alaska

Description: From abstract: The Craig quadrangle, in southeastern Alaska, lies entirely within the Tongass National Forest and includes a large part of Prince of Wales Island, the largest island of the Alexander Archipelago. Sedimentary, volcanic, and metamorphic rocks of Paleozoic and Mesozoic age are exposed as complexly folded and faulted sequences. Paleozoic rocks occupy a broad geanticlinal area comprising Prince of Wales Island and the islands to the west. Metamorphosed Mesozoic rocks form a geosyncli… more

Geology of the Mount McKinley Quadrangle, Alaska

Description: From abstract: The Mount McKinley quadrangle, in south-central Alaska, includes parts of the Alaska Range, the Tanana and Kuskokwim lowlands, and the Kuskokwim Mountains. Schists of Precambrian age crop out in the northern foothills of the Alaska Range. Sedimentary and volcanic rocks of Paleozoic and Mesozoic age are exposed in the Kuskokwim Mountains, where little is known of their distribution and character, and in the Alaska Range, where they occupy the axial part and northern limb of a grea… more

Ground Water Test Well A, Nevada Test Site, Nye County, Nevada: A Summary of Lithologic Data, Aquifer

Description: Abstract: "ground-water test well A was drilled to a depth of 1,870 feet with rotary and cable-tool equipment. Only alluvial materials were penetrated. These were saturated below 1,605 feet. Pumping and bailing tests indicate that the minimum transmissibility of the alluvium is about 800 gallons per day per foot. The specific capacity was 1.9 gallons per minute per foot of drawdown after 1 hours of pumping at rates of both 41 and 60 gallons per minute. A suite of geophysical logs, a summary of … more

Handbook of Nuclear Safety

Description: Discussions are given of the factors that determine a critical mass, consequences of attaining a critical mass, theory of chain reactions, and margins of safety. Critical and safe conditions are included for the fissionable materi als, U-233, U-235, snd plutonium, both as pure metals and when alloyed with other metals. Considerations are given for heterogeneously and homogeneously moderated systems, and interactions occurring between units in air and water. (B.O.G.)

Heat Transfer to a Mist Flow. Technical Report No. 5

Description: An experimental and analytical study was made of the heat-transfer characteristics of a mist flow of steam and water droplets flowing vertically upward in a round tube. A simplified analytical model, based on momentum, mass, and energy considerations, was developed which shows qualitatively that severe temperature fluctuations are characteristic of such flows under constant-wall heat-flux conditions. The experimental data showed that the analytical model gave a fairly accurate qualitative descr… more

High Power Density Development Project Sixth Quarterly Progress Report: July-September 1961

Description: During the quarter the development program was continued as scheduled. Milestones that were reached included the successful irradiation of prototype Big Rock fuel bundles in VBWR to a level above 2500 MWD/T with power densities as high as 88 kw/1. Also completed was the scheduling computer specification followed by a formal solicitation of bids through the AEC. A summary of progress by task is presented here.

An Investigation of the Use of Acoustic Vibrations to Improve Heat Transfer Rates and Reduce Scaling in Distillation Units Used for Saline Water Conversion

Description: Report presenting a study to determine the feasibility of using acoustical energy to improve the economy of evaporator operation as related to saline water conservation. Some of the improvements to be sought are increased film heat transfer coefficients on the water side, possible promotion of dropwise condensation on the steam side, and reduced scale formation.

INVESTIGATIONS OF THE POTASSIUM-ARGON METHOD OF AGE DETERMINATION USING SOLID ISOTOPIC DILUTION AND GAS REMOVAL BY CRUSHING

Description: Preliminary work on a new technique of isotopic dilution analysis useful in the measurement of radiogenic Ar content of rocks or mineral samples in age determination is reported. Argon-38 is added to the sampies as the diluting isotope dissolved in a solid glassy silicate which approximates the pertinent properties of the sample. Crushing as well as melting can be used to extract the representative portion of gas needed to apply the isotopic dilution method. In the preliminary investigations or… more

LEAKAGE FROM PRESSURIZED CONTAINERS DURING LONG TERM STORAGE

Description: Concern for the protection of water-sensitive components by storage in pressurized containers prompted this study of leakage from pressurized containers. Work carried out to determine leakage rates, which will ensure a positive pressure within the container for a specified storage period, is summarized. These analyses considered molecular flow and two cases of viscous flow through physical gaps or holes in the container. (auth)

Limnology of Yellowstone Lake in Relation to the Cutthroat Trout

Description: Limnological data collected from 1954 to 1959 on surface currents, bottom currents, temperatures, bottom soils, water chemistry, plankton, bottom fauna, and higher aquatic plants are related to the biology of the cutthroat trout, Salmo clarki lewisi, in Yellowstone Lake (Wyoming). The lake, formed on Eocene lava, is oliotrophic and low in dissolved solids. Diatomus shoshone, Daphnia shoedleri, and Conochilus unicornis made up more than 90 percent of the macroscopic zooplankton by number. Upwell… more

A Low Dead-Time Neutron-Counting System

Description: A counting system capable of processing input pulses at an average rate in excess of 3 x lO/sup 5/ counts per second with less than 10% counting loss because of instrumental dead time is described. The system is capable of detecting thermal neutrons in the presence of a high gamma background. It consists of a fission counter, a preamplifier, linear amplifier, and integral discriminator. Components of the system are described in detail, and circuit diagrams and layout information are given. Fact… more
