Lost circulation technology development status

Description: Lost circulation is the loss of drilling fluid from the wellbore to fractures or pores in the rock formation. In geothermal drilling, lost circulation is often a serious problem that contributes greatly to the cost of the average geothermal well. The Lost Circulation Technology Development Program is sponsored at Sandia National Laboratories by the US Department of Energy. The goal of the program is to reduce lost circulation costs by 30--50% through the development of mitigation and characteri… more

Potential for efficient frequency conversion at high average power using solid state nonlinear optical materials

Description: High-average-power frequency conversion using solid state nonlinear materials is discussed. Recent laboratory experience and new developments in design concepts show that current technology, a few tens of watts, may be extended by several orders of magnitude. For example, using KD*P, efficient doubling (>70%) of Nd:YAG at average powers approaching 100 KW is possible; and for doubling to the blue or ultraviolet regions, the average power may approach 1 MW. Configurations using segmented apertur… more

Laser annealing of ion implanted CZ silicon for solar cell junction formation. Quarterly report No. 2

Description: Results on a contract to evaluate the merits of large spot size pulsed laser annealing of ion implanted silicon wafers for junction formation in solar cells are reported. Investigations on homogenization of the laser beam were continued. In addition to the 30 mm diameter fused silica rod with a 90/sup 0/ bend configuration, quartz tubes were obtained and briefly tried. Best results were obtained with the rod homogenizer. Laser annealing experimentation resulted in complete recrystallization of … more

EXPERIMENTAL INVESTIGATION OF THE EFFECTS OF ULTRASONIC VIBRATIONS ON BURNOUT HEAT FLUX WITH BOILING WATER. Quarterly Technical Progress Report No. 3, April-June 1961

Description: The heat-transfer loop was completed and is in operation. Difficulty was experienced in obtaining a sufficiently strong connection between the burnout- detector voltage tap and the heating element. This problem and its potential solution are described. The lack of means of obtaining controlled burnout prevented collection of data on the burnout effects of the ultrasonic field. (auth)

Efficiencies of gas neutralizers for multi-MeV beams of light negative ions

Description: Measurements are reported of the neutral and charged particle fractions produced by running beams of Li/sup -/, C/sup -/, O/sup -/, and Si/sup -/ at energies up to 7 MeV through gas cells of N/sub 2/, Ar, or CO/sub 2/. We discuss the implications of these measurements for the design of neutralizers to produce high energy light atom beams for heating or current drive in tokamaks.

HTGR-GT closed-cycle gas turbine: a plant concept with inherent cogeneration (power plus heat production) capability

Description: The high-grade sensible heat rejection characteristic of the high-temperature gas-cooled reactor-gas turbine (HTGR-GT) plant is ideally suited to cogeneration. Cogeneration in this nuclear closed-cycle plant could include (1) bottoming Rankine cycle, (2) hot water or process steam production, (3) desalination, and (4) urban and industrial district heating. This paper discusses the HTGR-GT plant thermodynamic cycles, design features, and potential applications for the cogeneration operation mode… more

Costs and benefits of automotive fuel economy improvement: A partial analysis

Description: This paper is an exercise in estimating the costs and benefits of technology-based fuel economy improvements for automobiles and light trucks. Benefits quantified include vehicle cots, fuel savings, consumer's surplus effects, the effect of reduced weight on vehicle safety, impacts on emissions of CO{sub 2} and criteria pollutants, world oil market and energy security benefits, and the transfer of wealth from US consumes to oil producers. A vehicle stock model is used to capture sales, scrappag… more

Response of Dual-Purpose Reinforced-Concrete Mass Shelter

Description: BS>A reinforced-concrete dual-purpose underground parking garage and personnel sheiter designed for a long-duration incident pressure of 40 psi was tested. The sheiter was exposed to shot Priscilla, an approximately 37-kt 700-ft balloon burst (June 24, 1957), at a ground range of 1600 ft (predicted 35-psi peak incident-pressure level). The recorded peak incident pressure at the shelter was approximately 39 psi. Postshot soil borings were made to obtain undisturbed samples for determining soil c… more

Research, development and demonstration of nickel-iron batteries for electric vehicle propulsion. Annual report for 1979

Description: Research progress in the development of Ni/Fe batteries (electrodes in particular) for the period is described. The negative plate demonstrated a reliable lifetime of almost 1000 cycles; 20 mm positive plates were proved feasible; prototype cells yielded output at about 50 Wh/kg and 100 Wh/liter; program goals of 20% greater than these figures appear feasible. 27 figures, 20 tables.

Energy conservation and energy decentralization: issues and prospects

Description: Views are presented of the seemingly paradoxical nature and irrationality of the energy system and the decisions that determine its evolution. An economic approach to energy decisions, while widely espoused and generally believed to be the underpinning of our system, appears not to be functioning in very-important areas. The result is enormous waste of economic and intangible resources to produce energy that could be effectively replaced by energy conservation at low costs. This inefficiency in… more

Geothermal power production: accidental fluid releases, waste disposal, and water use

Description: Environmental problems related to the use and disposal of fluids can accompany the operation of geothermal power plants using hot water resources (temperature > 150/sup 0/C). More than 100 kg of fluids must be extracted, processed, and disposed for each kW.h of electricity generated from a facility relying on a geothermal reservoir with fluids of 150/sup 0/C. The low thermal efficiencies of geothermal power plants result in large requirements for cooling water - over 7.4 x 10/sup 4/ m/sup 3//MW… more

Least cost planning from a customer's perspective

Description: In this paper, I offer some thoughts about least cost planning, not from the perspective of the regulator or utility, but from the perspective of a residential customer. The problem that I address is, as a homeowner in northern Virginia, I am about to make a long term fuel choice for my household, where the options include, natural gas, electricity and fuel oil. An additional choice is the energy efficiency capital investment in my home that could decrease my monthly fuel costs. My decision pro… more

Industrial cogeneration case study No. 3: Mead Corporation Paper Mill, Kingsport, Tennessee

Description: The design, operation, performance, economics and energy efficiency of the 25,000 kW co-generating power plant at the Mead Co. paper mill in Kingsport, TN are described, and compared with the efficiency of producing only process heat at the plant while importing electric power from a local utility. It was established that on-site co-generation consumed 2/3 of the energy that would have been required for on-site process heat generation plus purchased off-site-generated electric power and that co… more

Proposal to assemble a high resolution-electron sensitive-energy flow calorimeter in the NEULAND spectrometer

Description: A ..gamma.. catcher and a liquid scintillation calorimeter module in a simple configuration that is well suited to the investigation of several different neutrino induced processes are described. The variety of neutrino beams now available at Fermilab and synchrotron intensity and energy together with the high resolution calorimeter allow a multiplicity of experiments to be carried out with a single detector configuration.

Efficient forward conversion in a Raman generator

Description: Stimulated Raman scattering of an XeCl laser at 308 nm in a high pressure H/sub 2/ cell shows anomalously high conversion into first Stokes (S1) when a pumping geometry with a Fresnel number near unity is used. Specifically a quantum efficiency of 88% is obtained into S1. Comparison with a plane-wave model indicates that a theory including diffraction and 4-wave mixing may be necessary to understand the anomalous holdoff of the second Stokes component. 10 references.
