Columbia River temperature study at 100-F Area

Description: In August 1946 it was discovered that two effluent lines near the Columbia River at Hanford were damaged. The upstream effluent line has broken off 37 fact from the shoreline and the downstream effluent line had been bent and partly broken seventeen feet from shoreline and has swung downstream to a point about 50 feet from shorelines. This study was made to determine how fast and in what fashion the temperature of the effluent water is dissipated in the Columbia River under the present conditio… more

The X-Ray Spectra of the Last-Row Elements

Description: Abstract: X-ray energy level diagrams as given in the literature are tabulated for radium, thorium and uranium. A level scheme for protoactinium is derived from the published data. After a brief review of the use of X-ray data in studying outer electronic structure, it is pointed out that differences in the X-ray spectra should exist depending on whether the outer electrons are in f or d orbitals. The observed separation of the OI and OII levels in thorium and uranium indicated that the f lev… more

The Effects of Fast Neutrons on the Ability of Mice to Take Forced Exercise

Description: From abstract: "In an attempt to gain some insight into the physiological condition of mice surviving massive doses of radiation, a study of their vitality was undertaken. It was assured that the ability of these animals to do forced work would be a measure of their vitality, Stimulating exposed animals to run in exercise wheels to their fullest capacity, has resulted in a demonstration of a striking vitality less during a post-irradiative period, when no other effects are demonstrable by gross… more

Recovery of Uranium From Beta Salvage Residues by Vapor Phase Chlorination With CCl₄

Description: Abstract: A simple process to recover the bulk of the uranium from ignited beta salvage residues was sought. In preliminary experiments a vapor phase chlorination with CCl₄ for about four hours followed by water and nitric acid leaching was found adequate. Recoveries are estimated at 60 to 90% of the total uranium content.

PREVENTION OF FISSION PRODUCT DIFFUSION

Description: The favorible attention being given graphite as a fuel rod material calls attention to the need for preventing diffusion of fission products from the fuel rods. The methods of prevention include painting the surface of the rod with an impermeable organic synthetic composition, enclosing the rods in metal cans, electroplating the rods with a suitable metal, or covering the surface with some type of inorganic ceranmic glaze. Each of these methods is evaluated as to feasibility. (M.H.R.)

300 Area, February 12 through February 18

Description: Extrusion was run on one day, February 2, and a total of 271 billets (178 Type G, 12 type BT, and 81 red band) were processed. Two failures occurred among the red band billets; UM 6610 had begun to melt in the furnace and TX 3323 disintegrated on being extruded through the die. Samples of these billets are being checked chemically and metallurgically in an attempt to ascertain the cause for the hot-short characteristics of these billets. A sample cut from a rod which possessed zero strength (fe… more
