Determination of Rare Earths in Refined Uranium : Topical Report

Description: Abstract: "Rare-earth analyses were performed on several samples of refined uranium oxide and nitrate, using a modified cellulose column procedure. Rare earths were not detectable in samples of 0.03 shotgun of less. Detection limits were from 0.0005 to 0.015 ppm. Negligible quantities of low-cross-section rare earths were found in less pure uranium samples, obtained during start-up operations of the pilot plant at the Feed Materials Production Center, primarily those rare earths of greater than… more

Proposed study program of the effects on Hanford of a dam at Columbia River mile 348

Description: At the request of Hanford Operations Office, Atomic Energy Commission, a study was made of the effects on the Hanford Facilities of a navigation and power dam at Columbia River mile 348, about five miles upstream of the 300 Area. The original study was based on a nominal slack-water pool elevation of 395 to 400 feet at the dam location. A supplemental study evaluated the effects on plant facilities of a dam at the same location but with slack-water pool elevation of 385 feet. In addition to eff… more

Proposal for irradiation of uranium swelling capsule

Description: To date, no data is available on the swelling rates of unrestrained unalloyed uranium rods operating at 450--630C core temperature and 250--350C surface temperature. These temperature ranges are of extreme interest in the Hanford fuel element development program. To obtain information on the effect of cladding restraint, exposure, and the above temperatures, on uranium swelling rates, a series of experiments is being designed for irradiation in Hanford reactors. The experimental assembly consis… more

The Path of Carbon in Photosynthesis. XIV.

Description: It seems hardly necessary to repeat to an audience of this kind the importance of the process known as photosynthesis in the interaction and the interdependence of organisms and in the very existence of life as we know it. This process by which green plants are able to capture electromagnetic energy in the form of sunlight and transform it into stored chemical energy in the form of a wide variety of reduced (relative to carbon dioxide) carbon compounds provides the only major source of energy f… more

Bubble Formation: A Bibliography

Description: Bubble phenomena have been given a new meaning with their study in relation to the kinetic behavior of reactors. Prior to their study in relation to physics, the bulk of work on bubble phenomena concerned naval engineering problems of behavior in cavitation and water entry behavior. This bibliography is intended to fill the need of the reactor physicist as well as the naval engineer. An attempt has been made to include all available references on bubble phenomena and associated effects. A subje… more

Methods for the Study of Gas-Metal Reactions in Ultra-High Vacuum

Description: A critical review of the methods reported in the literature for the study of gas-metal reactions in high and ultra-high vacuum systems is given. Experimental apparatus and techniques based on volumetric, gravimetric, magnetic, and other properties of the metals including work function, accommodation coefficient, resistivity, and others have been used. A volumetric method, based on a determination of rate-of-reaction, was selected as most readily applicable to the proposed investigation. (auth)

RESEARCH AND DEVELOPMENT IN THE FIELD OF THORIUM CHEMISTRY AND METALLURGY. VOLUME I. PREPARATION OF ELECTROLYTIC CELL FEED FOR PRODUCTION OF THORIUM METAL. Final Report

Description: A research and development program in the field of thorium chemistry and metallurgy was conducted. Most of this activity was directed toward the development of techniques for the production of metal by fused salt electrolytic approaches, little effort being proportioned to the preparation of an electrolyte for the process. An aqueous method for the preparation of an anhydrous cell feed was set up and operated for several months. Relatively high operating expense and difficulties with materials … more

FUNDAMENTALS OF DIFFUSIONAL BONDING--IV. Fourth Annual Progress Report for July 1, 1958 through June 30, 1959

Description: Investigatlon of interdiffusion in the aluminumuranium system and of the effects of applied pressure on such systems was about completed. The growth kinetics of the UAl/sub 3/ phase were determined at 400 to 600 C and at pressures of 1 1/4, 5, and 10 tsi. The origin of the macroscopic defects occurring in the UAl/sub 3/ layer during interdiffusion was clarified. The solubility range of UAl/sub 3/ was determined by a nuclear track emulsion technique to be about 2.6 at.% uranium. Exploratory runs… more

FUNDAMENTALS OF DIFFUSIONAL BONDING--III. Third Annual Progress Report for June 30, 1957 to June 30, 1958

Description: An investigation has been begun of interdiffusion in the aluminum- uranium system and of the effects thereon of applied pressure. In confirmation of the results of other investigations, it has been found that UAl/sub 3/ layer growth is accelerated by increasing applied pressure. The growth kinetics are characterized by a transient'' period, during which growth occurs non- parabolically, which is followed by a steady state'' period of parabolic growth. Interesting correlations are shown to exist… more
