HASL Aerial Survey System

Description: Radioactive debris from nuclear detonations may fall out over an extensive area. A rapid evaluation of the distribution of such surface contamination cam be obtained by an aircraft mounted detector. The gamma field measured in the aircraft can be related to the intensity on the ground. The HASL Top Hat'' system measures the radiation intensity, in an aircraft, at any altitude up to 1500 feet. The data are continuously compensated to the reading that would be obtained if the measurements were ta… more

Quantization of Crystal Vibrations

Description: "Although the Born-von Karman treatment of the dynamics of crystal lattices is superior to that of Debye, the conABSTRACTS tinuum model of Debye is more amenable to computation; therefore the Debye treatment is used to obtain frequencies at a maximum energy. From the classic Hamiltonian of the solid, quantization is carried out by the Schroedinger method. The thermodynamic functions are obtained, and the mean square displacement is derived"

The Partition of Oxygen Between Sodium and Tantalum

Description: We now proceed by finding a relation between the O2 pressure and the mole fraction of oxygen in the condensed phase for each phase and then equate the O2 pressures to get a relation between the mole fractions of oxygen in the two phases.

Adsorption of Zirconium-Niobium on Silica Gel

Description: From abstract: "Adsorption of radioactive zirconium-niobium from uranyl nitrate solutions by silica gel was increased by increasing the temperature and time the solution contacts silica gel, and decreased by "aging" the solutions before contacting the silica gel."

The Effect of Sodium Vapor Formation on the Operation of the Enrico Fermi Reactor : an Estimate

Description: This technical report presents the results of some simplified calculations concerning the two-phase flow of sodium in the Enrico Fermi reactor. The rather large value for the specific volume of sodium vapor coupled with the resistance of the top axial blanket sections resulted in large pressure drops for even small values (by weight) of net vapor. It is concluded that the formation of any sodium vapor in the Enrico Fermi reactor produces "boiling disease", i.e. triggers an unstable condition wh… more

Betatron Oscillation Frequency Shift Due To "N-Errors"

Description: "Expressions are found to relate DELTA gamma to the n-errors.'' It is demonstrated that the integral n-value concept'' is of no use in the present case. A modification of integrated n-value'' is suggested."

Extension of Operating Life of KAPL-30 Thimble

Description: In June of 1957, the KAFL Pressure Systems and Pressure Vessels Review Board completed their evaluation of the radiation damage to the KAPL-30-4 carbon steel thimble. The Board decided that it was safe to extend the operating life of the thimble from 9 to 16 MIM cycles, subject to review if further extended low temperature operation occurs. This memorandum summarizes the data and evaluation which were the basis for the decisions and recommendations of the KAPL Pressure Systems and Pressure Vess… more

A Study of Uranium Deposits in the Copper Mountain Area: Fremont and Hot Springs Counties, Wyoming

Description: Report documenting a study of the Copper Mountain area to "evaluate the potential uranium production to determine, if possible, the origin and conditions of deposition of the uranium; and suggest possible guides to prospecting in this and geologically similar areas. All known radioactive deposits were examined and samples were collected for special studies and for assay of uranium content" (p. 5).

Irradiation of Wrought Uranium Plate

Description: From abstract: "Wrought uranium plate, clad in 1100 aluminum with a nickel bonding layer, was irradiated to a maximum exposure of 1600 MWD/T in the MTR and was demonstrated to be suitable as a fuel element material. Beta-transformed plate, or beta-transformed plate that was cold stretched 2-1/4 per cent, did not change appreciably in dimensions but roughened on the surface. As-rolled plate increased in length, but did not roughen. Irradiation reduced the strength and virtually eliminated the du… more

Sodium Boiling Calculations

Description: The equations are derived for making rough calculations of the pressure drop required to produce a given mass flow through a subassembly for a given heat generation for cases where the vapor volume fraction is 0.9 or less. The ratio of vapor velocity to liquid velocity is left as a parameter that is varied form unreasonably low to unreasonably high values.
