Category I structures program. [PWR; BWR]

Description: The objective of the Category I Structure Program is to supply experimental and analytical information needed to assess the structural capacity of Category I structures (excluding the reactor cntainment building). Because the shear wall is a principal element of a Category I structure, and because relatively little experimental information is available on the shear walls, it was selected as the test element for the experimental program. The large load capacities of shear walls in Category I str… more

Characterization of muntjac DNA

Description: Sister chromatid exchange (SCE) in muntjac chromosomes is generally proportional to the chromosomal DNA content, but the SCE frequency is reduced in the heterochromatic neck region of the X chromosome. The physical properties of muntjac DNA and the kinetics of repair of UV damage in muntjac heterochromatin and euchromatin were examined and compared with the distribution of sister chromatid exchange.

Coal materials handling/coal feeder development, Phase I. 2nd quarterly technical progress report, January-March 1981

Description: The essential objective of Phase I of our program is to demonstrate extended capabilities for the Linear Pocket Feeder (LPF). This requires extensive modification of both our test facility and the LPF. At this time we estimate that delays in modifications will prevent our testing the LPF until at least mid-May, a month and a half later than originally scheduled. However, we have reviewed our test plan and facility operation in detail and conclude that testing can probably be completed by the en… more

Development of copper sulfide/cadmium sulfide thin-film solar cells

Description: The purpose of this work has been to identify aspects of cell fabrication and treatment which are critical for achieving high efficiency Cu/sub 2/S/CdS solar cells. In approaching the problem several comparisons were made of the effects of specific steps in two methods of cell fabrication. These methods had previously given cells of about 6% and a maximum of 9% efficiency. Three areas requiring special attention and specific means to achieve acceptable results were identified. (1) The Cu/sub 2/… more

Effects of Pressure and Temperature on the Thermal Properties of a Salt and a Quartz Monzonite

Description: Measurements have been made of thermal conductivity, diffusivity, and linear expansion as a function of temperature (to 573 K) and hydrostatic pressure (to 50 MPa) on two rocks, Avery Island domal salt and Climax Stock quartz monzonite. For Avery Island salt the thermal properties do not show any pressure dependence and are approximately the same values as for single crystal halite at 0.1 MPa. The lack of pressure dependence is attributed to the high symmetry of halite (cubic) and to its low st… more

Electrostatic air filters generated by electric fields

Description: This paper presents theoretical and experimental findings on fibrous filters converted to electrostatic operation by a nonionizing electric field. Compared to a conventional fibrous filter, the electrostatic filter has a higher efficiency and a longer, useful life. The increased efficiency is attributed to a time independent attraction between polarized fibers and charged, polarized particles and a time dependent attraction between charged fibers and charged, polarized particles. The charge on … more

Energy utilization: municipal waste incineration. Final report

Description: An assessment is made of the technical and economical feasibility of converting municipal waste into useful and useable energy. The concept presented involves retrofitting an existing municipal incinerator with the systems and equipment necessary to produce process steam and electric power. The concept is economically attractive since the cost of necessary waste heat recovery equipment is usually a comparatively small percentage of the cost of the original incinerator installation. Technical da… more

Geothermal reservoir engineering code: comparison and validation

Description: INTERCOMP has simulated six geothermal reservoir problems. INTERCOMP's geothermal reservoir model was used for all problems. No modifications were made to this model except to provide tabular output of the simulation results in the units used in RFP No. DE-RP03-80SF-10844. No difficulty was encountered in performing the problems described herein, although setting up the boundary and grid conditions exactly as specified were sometimes awkward, and minor modifications to the grid system were nece… more

Glassy thin films. Final report

Description: This report describes the initial results of a long term program to study order-disorder phenomena in dielectric thin films. To achieve this overall goal, an apparatus was constructed to permit the codeposition of a glass-forming additive such as SiO/sub 2/ in a polycrystalline matrix film such as MgO. The extent of crystallinity of mixture films in the MgO-SiO/sub 2/ system was determined using techniques developed for x-ray powder diffraction. With this approach, it was determined that the ad… more

Measurement of outdoor noise levels adjacent to K-25 facility, ORGDP

Description: In order to obtain baseline data on environmental sound for a report on the expected environmental effects of constructing an incinerator adjacent to the ORGDP, an abbreviated measurement program was carried out. Ten measurement locations were selected for the measurements, six being representative of the ORGDP fenceline, and four representative of the surrounding area. Measurements consisted of short-term octave-band measurements and one-half hour A-weighted exceedance levels. It had been prev… more

Molecular potentials and relaxation dynamics

Description: The use of empirical pseudopotentials, in evaluating interatomic potentials, provides an inexpensive and convenient method for obtaining highly accurate potential curves and permits the modeling of core-valence correlation, and the inclusion of relativistic effects when these are significant. As an example, recent calculations of the chi/sup 1/..sigma../sup +/ and a/sup 3/..sigma../sup +/ states of LiH, NaH, KH, RbH, and CsH and the chi/sup 2/..sigma../sup +/ states of their anions are discusse… more

Overview of coal conversion

Description: The structure of coal and the processes of coal gasification and coal liquefaction are reviewed. While coal conversion technology is not likely to provide a significant amount of synthetic fuel within the next several years, there is a clear interest both in government and private sectors in the development of this technology to hedge against ever-diminishing petroleum supplies, especially from foreign sources. It is evident from this rather cursory survey that there is some old technology that… more

Plan for the future of neutron research on condensed matter: an Argonne National Laboratory report prepared in response to the Report of the Review Panel on Neutron Scattering

Description: The Review Panel on Neutron Scattering has recommended an expanded budget to allow systematic development of the field. An alternative plan for the future of neutron research on condensed matter is presented here, in case it is not possible to fund the expanded budget. This plan leads, in a rational and logical way, to a world-class neutron source that will ensure the vitality of the field and exploit the many benefits that state-of-the-art neutron facilities can bring to programs in the materi… more

Positron lifetime and Doppler broadening techniques applied to irradiation-damaged silver

Description: Positron lifetime and Doppler broadening measurements have been used to study defect production resulting from room temperature irradiation of pure silver by D-T fusion neutrons or energetic protons. Use of the positron annihilation analysis has established that the surviving defects from both irradiations have the same dose dependence and that defect concentration can be quantitatively measured and compared to damage models. The relative merit of the lifetime and Doppler broadening measurement… more

Pressure measurements of nonplanar stress waves

Description: A useful gage has been developed for measuring pressure of nonplanar or obliquely incident stress waves. The measurements made with these gages are not as precise as direct strain gage measurements, but are very good considering the conditions under which these gages are used. We feel a need to further develop our ability to measure nonplanar stress waves in the 0 to 10 kbar range. Carbon or ytterbium will probably be chosen for the sensing element.

Study of the production of ethanol from sugar beets for use as a motor fuel. Final report, February 1, 1980-April 30, 1981

Description: This study was performed to assess the feasibility of producing fuel ethanol from sugar beets. Sugar beets are a major agricultural crop in the area and the beet sugar industry is a major employer. There have been some indications that increasing competition from imported sugar and fructose sugar produced from corn may lead to lower average sugar prices than have prevailed in the past. Fuel ethanol might provide an attractive alternative market for beets and ethanol production would continue to… more
