Flow field analysis (open access)

Flow field analysis

The average mean wind speed integrated over a disk is shown to be extremely close to the mean value of wind speed which would be measured at the center of a disk for most geometries in which a WECS (Wind Energy Conversion System) would operate. Field test results are presented which compare instantaneous records of wind speed integrated over a disk with the wind speed measured at the center of the disk. The wind field that a rotating element would experience is presented which has been synthesized from the outputs of an array of anemometers.

Grant request: to implement energy conservation measures as part of the state original and supplemental energy conservation plans (open access)

Grant request: to implement energy conservation measures as part of the state original and supplemental energy conservation plans

The program measures described in this document comprise a grant request to DOE under the Energy Policy and Conservation Act of 1975 and the Energy Conservation and Production Act of 1976. The amount requested, $5,555,000, will allow the extension, acceleration, and implementation of energy conservation activities already in progress in California. Accomplishments to date have included the adoption of residential standards, and the implementation of an energy survey program for public buildings. Efficiency standards have been established for refrigerators and room and central air conditioners, appliances which utilize a significant amount of residential energy. Before the end of 1977, efficiency standards will be established for clothes dryers, washers, and water heaters. Program elements are: technical/financial assistance; public awareness; standards setting; solar element; research/analysis/evaluation; and coordination and management.

Integrated system for production of neutronics and photonics calculational constants. Volume 5, Part B. Relativistic transformations between center-of-mass and laboratory systems for two-body nuclear reactions (open access)

Integrated system for production of neutronics and photonics calculational constants. Volume 5, Part B. Relativistic transformations between center-of-mass and laboratory systems for two-body nuclear reactions

A technique is described for transforming cross sections and secondary-particle energies between center-of-mass and laboratory systems for two-body nuclear reactions. The derivations of the relativistic transformations needed for this technique are also reviewed.

Introduction to albedo neutron dosimeters (open access)

Introduction to albedo neutron dosimeters

The design, operation, calibration, and performance of albedo neutron dosimeters are discussed. An albedo neutron dosimeter is designed to measure the flux of thermal neutrons which leave the body when a person is exposed to fast energy neutrons. The fast neutrons are scattered and moderated in the body, and many have lost most of their initial energy and emerge as thermal neutrons. The albedo neutron dosimeter is designed to detect this flux of thermal neutrons by using a thermal neutron detector. This could be any type of thermal neutron detector but in practical applications lithium fluoride (LiF) thermoluminescence dosimeters (TLDs) are most frequently used. Various types of albedo neutron dosimeters are described. (WHK)

Inventory and relative biological hazard of LMFBR core materials (open access)

Inventory and relative biological hazard of LMFBR core materials

Information on the composition of an LMFBR core by element has been collected on the basis of published design data and ORIGEN calculations. The mass quantities of structural materials, actinides, and fission products are in the ratio of 1:1.4:0.1 with actinides, particularly plutonium and neptunium, representing the major inhalation and ingestion hazard. Some of the fission products are present in quantities large enough to suggest that they warrant specific attention in source term analysis.

Polarized proton acceleration (open access)

Polarized proton acceleration

The question of whether polarized beams of 12 GeV or, preferably, higher energy can be produced at other existing or planned accelerators is explored. Sources of polarized H/sup -/ ions suitable for injection into accelerators appear to be feasible with intensities in the milliampere range (an order of magnitude better than present performance at Argonne). This would be sufficient to produce polarized beams of intensities comparable (though somewhat weaker) to those of unpolarized beams in high energy accelerators and luminosities not more than a factor of about 10 lower than those for unpolarized beams in storage rings, such as the CERN ISR or ISABELLE, the 400 GeV storage accelerator system now under design at BNL. The major question, then, is whether it is possible to maintain polarization in these accelerators during the acceleration process and during storage in a storage ring.

Secondary recovery of plutonium and americium from process waste streams by solvent extraction (open access)

Secondary recovery of plutonium and americium from process waste streams by solvent extraction

A solvent extraction process is being evaluated for the secondary recovery of plutonium and americium from Rocky Flats waste streams. The bidentate organophosphorus compounds dihexyl-N,N-diethylcarbamylmethylene phosphonate and its dibutyl analogue have been shown to be selective extractants for the actinides from solutions of nitric acid. The results from laboratory test runs in which the organophosphorus extractants were used for processing secondary waste solutions will be presented. Solvent extractant properties and purification procedures are discussed.

Solute-travel time estimates for tile-drained fields. III. Removal of a geothermal brine spill from soil by leaching (open access)

Solute-travel time estimates for tile-drained fields. III. Removal of a geothermal brine spill from soil by leaching

The time required to leach a slug of saline, sodic geothermal brine from the point of injection to the tile outlet of an artificially drained field is calculated. Sprinkler, complete, and partial ponding leaching methods are compared as a function of drain spacing and initial location of the spill, with ponding requiring more water but less time to leach brine out of the system for all situations except where the brine spill occurs near the midpoint between tile lines. Calculation results are presented in dimensionless parameters which scale the drainage system dimensions and the soil water transport properties. A simple calculation is proposed to estimate the volume of leaching fluid required to remove excess Na/sup +/ from the exchange complex, and was found to be in good agreement with the results of laboratory soil column experiments. For fine-textured soils in the Imperial Valley of California it may require up to 30 pore volumes of leaching fluid to lower Na/sup +/ concentrations if saturated gypsum solution is used in reclamation. The results of these calculations suggest that reclamation of fine textured soils could require a prohibitive amount of time unless the brine spill is localized around a drain.
