Eddy Transport in Liquid-Metal Heat Transfer (open access)

Eddy Transport in Liquid-Metal Heat Transfer

This report seeks to "develop a practical method of evaluating the eddy diffusivity of heat transfer for liquid metals, so that it can be incorporated into the more or less standard theoretical methods to give heat transfer coefficients which are in reasonable agreement with experimental facts"--from introduction.

Magnetic Acceleration of a Plasma by a Rail Source (open access)

Magnetic Acceleration of a Plasma by a Rail Source

Abstract: "Two parallel wires close together with an arc between them form a hairpin-type of current configuration which should magnetically propel the plasma of the arc. By the time-of-flight measurements with probes it has been demonstrated that directed translational energies of 290 ev can be imparted to deuterons in a plasma produced by a high-current pulsed arc at the tips of two titanium wires loaded with deuterium. It is believed that three deuterons are actually magnetically propelled."

An Immobilized Plasma in a Nonuniform Field : (IBM Machine Code Title "PLANOUNF1") (open access)

An Immobilized Plasma in a Nonuniform Field : (IBM Machine Code Title "PLANOUNF1")

Abstract: "The self-consistent equations have been found for a plasma which lies in a mainly unidirectional magnetic field, which has a circular symmetry and which has a harmonic variation in the direction of the magnetic field. The equations have been solved in two cases, 1) where the harmonic variation of the field is finite and the plasma is weak, and 2) where the plasma is strong but the harmonic variation of the field is weak. The configurations thus found can form an important starting point for calculations of the stability of plasmas."

Results of Diamond Drilling Mesas 1, 2, 3, and 4, Lukachukai Mountains, Northeastern Arizona (open access)

Results of Diamond Drilling Mesas 1, 2, 3, and 4, Lukachukai Mountains, Northeastern Arizona

From purpose and scope: Diamond drill exploration of the Lukachukai district was undertaken to find minable bodies of uranium ore and to determine whether sufficient reserves were present to warrant construction of a local mill. A minimum of 30,000 feet and a maximum of 50,000 feet of drilling were assigned to block out ore in the discovery area, Mesa I (pl. 1.). It was anticipated that some of the footage might be used to test Mesa II should the area become accessible. With access to Mesas II and IV subsequently provided by roads constructed by F. A. Sitton, Inc., and access to Mesa III furnished by a road constructed by the Atomic Energy Commission, the area available for drilling was eventually increased by some three and a half times. With no increase in allotted footage, the hole density was correspondingly decreased,

A Method for Neutron Energy Measurement (open access)

A Method for Neutron Energy Measurement

This technical report discusses a method proposed to measure neutron energies by accurately determining the momenta of recoil protons in a magnetic spectrometer specially designed for this purpose. The main consideration in the design of the spectrometer is the shielding of the detector from the high radiation background associated with intense neutron beams.

The Hall Effect in Neutron Irradiated and Annealed Graphite (open access)

The Hall Effect in Neutron Irradiated and Annealed Graphite

Abstract. Irradiated Whiting graphite possesses a small negative or a positive Hall constant, depending upon the dosage. Annealing at 500 degrees C for 1 hour in helium results in a Hall constant which is large in magnitude and negative in sign. The properties of the annealed graphite are presumably close to those of the original unirradiated material. Unirradiated AGOT-K graphite has a large, negative Hall constant. A mechanism is suggested which accounts for the change in sign of the Hall constant as a result of neutron bombardment.

Separation of Tuballoy From Gunk Solutions by Sulfite Precipitation (open access)

Separation of Tuballoy From Gunk Solutions by Sulfite Precipitation

Summary: A method is presented for the precipitation of tuballoy, apparently as a tubanyl ammonium sulfite, from gunk solutions containing the contaminants encountered in the recovery cycle. The impurities are not precipitated under the conditions employed, and their amounts in the product are reduced to values which can be attributed to occlusion. The recovery of tuballoy on one precipitation ranges from 99.5% to 99.9%.
