The Development of a Melting Method for Conversion of Zirconium Sponge to Corrosion Resistant Ingot

Description: This report covers an investigation meant to find the feasibility of producing corrosion resistant zirconium from sponge by special melting techniques. The zirconium metal has certain required specifications, such as: the metal must be free from bafnium, and it must be free from other impurities of undesirable neutron cross section.

Electroplated Metals on Uranium for Aluminum Cladding

Description: Abstract: "Aluminum-clad nickel-plated uranium is corrosion resistant in boiling water. Samples with intentional defects in the aluminum-nickel clodding layers, after testing for more than 300 hr. showed no sign of rapid failure. The study of electroplated metals on uranium for aluminum cladding has defined the effects of several processing variables on the corrosion resistance. The quality of the uranium and the quality of the aluminum-nickel bond were important. Heat treatment and vacuum outg… more

Equilibrium Extraction Characteristics of Alkyl Amines and Nuclear Fuels Metals in Nitrate Systems. Progress Report No. V for the Period July 1 - September 30, 1959

Description: Extraction of HNO3 by triaryl amine was studied by equilibrating equal volumes of aqueous and organic phases at 25C. At HNO3 concentrations of 2 to 10 N the acid in the organic phase in excess of that equivalent in the amine concentration was proportional to the concentration of HNO3 in the equilibrated aqueous phase. other workers report similar results with nitric acid and tri-n-octyl amine in benzene. Zirconium extractions carried out at 10g Zr/1 with 0.35 M TLA nitrate in toluene showed a f… more

Fate of Fission Product Gases in the Coolant Stream

Description: The quantity and characteristics of fission products in coolant gases due to leaking fuel elements are discussed. It is concluded that the rare gases, the alkali metals, the halides, and Sb may act as permanent gases to a considerable extent. The other fission products are expected to condense out completely on walls or as dust consisting of metals, carbides, and oxides.

Flux in a Rectangular Cavity.

Description: A problem proposed by E. Hart to determine whether there are locally high or low neutron densities at the corners of a cubical cavity in a graphite lattice. To simplify the computations consider an infinite two dimensional lattice with a square cavity that has a point source of neutrons at the center (see Figure 1).

Heat Transfer Fluids for Fuel Element Cans

Description: The maximum temperature in the interior of the fuel element could be greatly reduced by incorporating a liquid between the fuel element and the outer can to increase-heat transfer rates. It is of interest to consider what liquids would be chemically compatible with graphite and the actinide carbides. Elements which melt below 1100 and boil above 1400 deg C that form no stable solid carbides, include Cu, Ga, TI, Ge, Sn, Pb, Sb, Bi, and compounds include GeP, GeS, GaP, Ga/sub 2/S, GaTe, GaAs, SnT… more

Neutron Streaming in a Cylindrical Cavity

Description: The free streaming of neutrons in a cylindrical cavity is investigated. Using experimental data for the flux distribution along the walls, the direct beam hole loss and leakage into the target from the lattice is estimated for the MTA system.

Preliminary Report on Uranium Deposits in the Wind River Basin, Wyoming

Description: Abstract: Uranium was discovered in the Gas Hills of the Wind River Basin by Mr. Nail E. McNeice of Riverton, Wyoming while he was prospecting with a Geiger counter in September 1953. Field parties of the Atomic Energy Commission started work in the area in October 1953.

A Preliminary Survey of Radioactive Constituents in Rainwater at ORNL

Description: Technical report surveying radio-chemical analyses by ORNL's Analytical Chemistry Division and Health-Physics Division of large volumes of rainwater for plutonium, uranium, and fission products. Overall, carrying efficiencies for Al(OH)3 scavenging of rainwater were determined for these elements, as well as for Pu and U. [From Abstract, Introduction]

Properties of Uranium-Bismuth Reactors for Computer Programs

Description: "This memorandum is a survey of the properties of [U-Bi] reactors for U235 as a fuel and U233 as a fuel using a larger density for the graphite [for calculations]. This will include properties of the core and various reflectors which will be useful for large machine calculations of reflector savings, fast and thermal fluxes, and quantities of interest based on two-group calculations."

Radioactive Particle Fallout in the Hanford Environs from Nevada Nuclear Explosions Spring-1953

Description: Various organizations in the Biophysics Section of the Radiological Sciences Department participated in evaluating local radioactive particle fallout as influenced by the nuclear explosions at the Nevada Proving Grounds during the early part of 1953. Data collected from approximately 50 air monitoring stations operated by the Regional Survey forces were used to determine the trend of radioactive particle concentrations in the atmosphere between March and June. These measurements were suppleme… more

Reconnaissance of the Lower Chinle Along the Colorado River Between the Moab and Dewey Bridges, Grand County, Utah

Description: Abstract: The sandstones and conglomerates contained in the Shinarump conglomerate stratigraphic level in the area along Colorado River between the Moab and Dewey bridges have been assigned to the lower Chinle. One small anomaly was located, but no favorable radioactive areas were found. Gray-green mudstone and siltstone zones and carbonated material are absent.

Ru-106 - Rh-106 Activity

Description: In obtaining the results reported here a double focusing magnetic type spectrometer was used. Momentum spread was about 1%, and in most cases 2560 counts per point were taken. An end window Geiger tube was used as a detector. The window was of mica with areal density of 1.6 mg/cm2.
