Durability of adhesive bonds to uranium alloys, tungsten, tantalum, and thorium. [U--Nb; Ta--10 percent W] (open access)

Durability of adhesive bonds to uranium alloys, tungsten, tantalum, and thorium. [U--Nb; Ta--10 percent W]

Long-term durability of epoxy bonds to alloys of uranium (U-Nb and Mulberry), nickel-plated uranium, thorium, tungsten, tantalum, tantalum--10 percent tungsten, and aluminum was evaluated. Significant strengths remain after ten years of aging; however, there is some evidence of bond deterioration with uranium alloys and thorium stored in ambient laboratory air.

FFTF report: FFTF piping installation and welding techniques (open access)

FFTF report: FFTF piping installation and welding techniques

The main sodium piping with a diameter of 16'' or 28 '' is being installed at the FFTF construction site starting in December 1974. The supplier and authority demarcations are: Combustion Engineering supplies the reactor vessel, guard vessel and adjoining pipes and uses the machine welding equipment ''Dimetrics''; for the piping system of the primary and secondary loops the pipes manufactured by Rollmet at HUICO, Pasco, were delivered and prefabricated there, as far as compatible with the installation. ''Astroarc'' welding machines are used by Bechtel for the piping prefabrication in the weld laboratory as well as on site at the construction site. Technical welding problems occurring during the course of the installation at the construction site and several during this time are described. At present 6 weld seams in the reactor and 14 weld seams in the secondary loop are accepted. The requirement exists to carry out as many welds as possible automatically, in order to produce sodium pipe welds of high technical quality and which are reproducible. The welding equipment is described.

Gas laser cells: stress analysis of cylindrical cells with radial injection of electrons (open access)

Gas laser cells: stress analysis of cylindrical cells with radial injection of electrons

The problem is to develop a design procedure for pressurized cylindrical excimer laser cells. Excitation of the pressurized laser gas is by a short pulse of high energy electrons injected through the cell wall. In traversing the wall, the electrons lose energy and heat the wall. Because of rapid gas heating, a shock wave is generated which produces an additional load on the wall. Selected for analysis is a simple, conservative model of a cylindrical cell pressurized to double the shock pressure. The hoop stress is given by the product of a coefficient, which accounts for the shock over pressure, and the classical hoop stress relation. The shock over pressure coefficient is linearly related to the volumetric energy deposition with slope inversely proportional to the product of initial gas density, specific heat, and temperature. The derived equation is applied to a design study of a selected range of laser parameters. The applicability of this simple analysis is discussed. Electron energy absorption curves for several metals are also presented.

Development of a Low Cost Versatile Method for Measurement of HTO and HT in Air (open access)

Development of a Low Cost Versatile Method for Measurement of HTO and HT in Air

A low cost, highly sensitive method for the measurement of HTO and HT in air has been developed. The air is first passed through an ethylene glycol bubbler to remove the HTO, then through a heated palladium catalyst where the HT gas is oxidized to HTO and collected in a second ethylene glycol bubbler. The tritium collected by the bubblers is measured by liquid scintillation counting. Recoveries of 95 to 100% with air flow up to 750 cm/sup/3 /min are routinely obtained. The sensitivity of the method is basically dependent on the liquid scintillation counter background and the counting techniques employed. Several applications of this method of tritium air sampling are in use at Mound Laboratory and are discussed.

Environmental impact assessment: chemical explosive fracturing project, Petroleum Technology Corporation/Sutton County, Texas (open access)

Environmental impact assessment: chemical explosive fracturing project, Petroleum Technology Corporation/Sutton County, Texas

A proposed two-well stimulation test to be carried out in Sutton County, Texas is described. Work will be performed in the lenticular tight sand formation of the Val Verde-Kerr Basin to demonstrate the technical and economic feasibility of chemical explosive fracturing as a method of increasing gas deliverability in that formation. The purpose of the project's experimental design, which calls for the testing of two separate wells using different techniques, would be to obtain the maximum amount of information relating to the most effective method of stimulating this particular reservoir. Results will permit the direct comparison of the different completion techniques. Also the testing of more than one well in a given area will allow for the collection of complementary data with regards to the characteristics of the reservoir and the experimental results from the explosive stimulation. The environmental effects of the project are assessed. (JRD)

Computer-controlled sampling system for airborne particulates (open access)

Computer-controlled sampling system for airborne particulates

A self-contained, mobile, computer-controlled air-sampling system has been designed and fabricated that also collects and records the data from eight meteorological sensors. The air-samplers are activated automatically when the collected meteorological data meet the criteria specified at the beginning of the data-collection run. The filters from the samplers are intended to collect airborne $sup 239$Pu for later radionuclide analysis and correlation with the meteorological data for the study of resuspended airborne radioactivity and for the development of a predictive model. This paper describes the system hardware, discusses the system and software concepts, and outlines the operational procedures for the system. (auth)

Noise from cooling towers of power parks (open access)

Noise from cooling towers of power parks

A study is presented of the noise pollution problem for large power parks proposed for the future. Such parks might have an area of about 75 sq. miles, and a generating capacity up to 48000 MW. A comparative analysis has been done for natural and mechanical-draft wet towers as the major sources of acoustic power. Noise radiation from single isolated towers as well as from a dispersed array of towers has been considered for both types of cooling systems. Major noise attenuation effects considered are due to the atmospheric absorption and A- weighting. Conditions of 60F and 70 percent relative humidity in a still atmosphere have been assumed. (auth)

Optical timing receiver for the NASA laser ranging system. Part I. Constant-fraction discriminator (open access)

Optical timing receiver for the NASA laser ranging system. Part I. Constant-fraction discriminator

Position-resolution capabilities of the NASA laser ranging system are essentially determined by time-resolution capabilities of its optical timing receiver. The optical timing receiver consists of a fast photoelectric device, primarily a standard of microchannel-plate-type photomultiplier or an avalanche photodiode detector, a timing discriminator, a high-precision time-interval digitizer, and a signal-processing system. The time-resolution capabilities of the receiver are determined by the photoelectron time spread of the photoelectric device, the time walk and resolution characteristics of the timing discriminator, and the time-interval digitizer. It is thus necessary to evaluate available fast photoelectronic devices with respect to their time-resolution capabilities, and to design a very low time walk timing discriminator and a high-precision time digitizer which will be used in the laser ranging system receiver.

Vacuum system for the Livermore intense neutron source (open access)

Vacuum system for the Livermore intense neutron source

To fulfill the need for intense 14-MeV neutron sources for controlled thermonuclear reactor material damage studies, several accelerators will be built at the Lawrence Livermore Laboratory. A high-capacity vacuum system will be required to handle the large deuterium gas load needed to produce the beam current. Outgassing of tritium from the target necessitates special handling of the exhaust from the vacuum pumps. A vacuum system utilizing turbomolecular pumps was selected after comparing its performance with mercury vapor diffusion and titanium bulk sublimation/ion pumps. (auth)
