Effect of strain-gage surface preparation techniques on beryllium

Description: Beryllium is a metal sensitive to machining damage, causing a loss in mechanical properties. Since some mechanical abrading is often used in surface preparation for mounting strain gages, it is desirable to know whether the abrading produces flaws. Metallographic study of beryllium subjected to four different surface preparation methods was carried out. It was determined that the gentle abrading necessary for affixing strain gages produced a negligible density and depth of flaws and did not low… more

Conceptual design and systems analysis of photovoltaic systems. Volume I. Study summary. Final report

Description: This investigation of terrestrial PV systems considered the technical and economic feasibility for systems in three size categories: a small system of about 12 kW peak output for on-site residential use; a large 1500 MW central power plant contributing to the bulk energy of a utility system power grid; and an intermediate size system of about 250 kW for use on public or commercial buildings. In each category, conceptual designs were developed, performance was analyzed for a range of climatic re… more

Uranium-232 production in current design LWRs

Description: The spectrum-dependent zero dimensional depletion code, LEOPARD, was modified to permit a study of uranium-232 buildup in pressurized (PWR) and boiling water reactors (BWR). The results of the study showed good agreement with comparable calculations performed by Westinghouse for PWRs but poor agreement with General Electric calculations for BWRs. Differences noted were attributed to the nuclear cross section data and, in the case of the BWR results, the method of calculation. This study indicat… more

Analysis of the factors that impact the reliability of high level waste canister materials

Description: The analysis encompassed identification and analysis of potential threats to canister integrity arising in the course of waste solidification, interim storage at the fuels reprocessing plant, wet and dry shipment, and geologic storage. Fabrication techniques and quality assurance requirements necessary to insure optimum canister reliability were considered taking into account such factors as welding procedure, surface preparation, stress relief, remote weld closure, and inspection methods.

Microsphere Separation Techniques. Final Report

Description: A multiple contact adhesion model has been derived to explain the charge observed on silica dust. This model has good agreement with the observed adhesion of microspheres and microballoons. From theoretical arguments, it appeared feasible that surface acoustic waves could be used to overcome the electrostatic adhesion between a particle and surface, and be used to move the particle along the surface in a controllable fashion. In an inverted geometry, evidence for resonance in the hollow microba… more

Air assisted fuel injection and ignition: a new concept to improve the automotive diesel engine. Monthly technical status report, May, 1977

Description: It is anticipated that by employing high temperature, high pressure air to inject fuel into the combustion chamber of a diesel engine, the combustion process can be improved significantly. Better combustion should lead to better fuel economy, lower emissions of nitrogen oxides and unburnt hydrocarbons, less smoke, less noxious odors, reduced noise, less vibrations, increased power per unit weight of the engine, improved cold starting capability and engine operation with a wider range of fuels. … more

Environmental impact assessment: chemical explosive fracturing project, Petroleum Technology Corporation/Columbia Gas Transmission Corporation, Lincoln County, West Virginia

Description: This review of the plans for the chemical explosive fracturing of the Devonian shales of Lincoln County, W. Va., for natural gas stimulation includes an assessment of the environmental effects. Alternatives, mitigating factors, cost benefit analysis, potential conflicts with other plans and programs, and relation of short-term use to long-term productivity are covered briefly. It is concluded that the proposed project does not constitute a major federal action significantly affecting the enviro… more

NADAC and MERGE: computer codes for processing neutron activation analysis data

Description: Absolute disintegration rates of specific radioactive products induced by neutron irradition of a sample are determined by spectrometric analysis of gamma-ray emissions. Nuclide identification and quantification is carried out by a complex computer code GAMANAL (described elsewhere). The output of GAMANAL is processed by NADAC, a computer code that converts the data on observed distintegration rates to data on the elemental composition of the original sample. Computations by NADAC are on an abs… more

Measurement of the neutron-induced fission cross section of /sup 237/Np relative to /sup 235/U from 0. 02 to 30 MeV

Description: The /sup 237/Np//sup 235/U fission cross section ratio has been measured from 0.02 to 30 MeV. Using the threshold method, a value of 1.294 +- 0.019 is obtained for the average cross section ratio in the interval from 1.75 to 4.00 MeV.

Imperial Valley Environmental Project: progress report

Description: Progress is reported in six areas of research: air quality, water quality, ecosystem quality, subsidence and seismicity, socioeconomic effects, and integrated assessment. A major goal of the air quality element is to evaluate the rate of emission of H/sub 2/S, CO/sub 2/, H/sub 2/, N/sub 2/, CH/sub 4/, and C/sub 2/H/sub 6/ from the operation of the geothermal loop experimental facility at Niland. Concentrations of H/sub 2/S were found to vary between 1500 to 4900 ppM by volume at the Niland faci… more

Fiscal impacts associated with power reactor siting: a paired case study

Description: The paper examines the fiscal impacts associated with siting nuclear-powered electrical stations. First, a framework for examining fiscal impacts is constructed. This framework consists of four elements: the ability of a local community to raise revenues, the degree to which this ability is used, the uses to which tax revenues are applied, and the effect of tax/expenditure decisions on the local economy. Changes in these four elements caused by the siting are termed fiscal impacts. Second, this… more

Design of a /sup 18/F production system at ORNL 86-inch cyclotron

Description: A target system for the production of /sup 18/F by proton bombardment of H/sub 2//sup 18/O was designed for the ORNL 86-inch cyclotron facility. The system consists of concentric titanium and aluminum cylinders. Oxygen-18-enriched H/sub 2/O circulates through the inner titanium cylinder and through an external heat exchanger with cooling water flowing in the annulus. Yields of 5.0 curies are expected for a 250-..mu..A proton beam current and 24-min irradiation time.
