Acoustic emission intrusion detector (open access)

Acoustic emission intrusion detector

In order to improve the security of handling special nuclear materials at the Oak Ridge Y-12 Plant, a sensitive acoustic emission detector has been developed that will detect forcible entry through block or tile walls, concrete floors, or concrete/steel vault walls. A small, low-powered processor was designed to convert the output from a sensitive, crystal-type acoustic transducer to an alarm relay signal for use with a supervised alarm loop. The unit may be used to detect forcible entry through concrete, steel, block, tile, and/or glass.

Apparatus for spot welding sheathed thermocouples to the inside of small-diameter tubes at precise locations

Equipment and procedures used to spot weld tantalum- or stainless-steel-sheathed thermocouples to the inside diameter of Zircaloy tubing to meet the requirements of the Multirod Burst Test (MRBT) Program at ORNL are described. Spot welding and oxide cleaning tools were fabricated to remove the oxide coating on the Zircaloy tubing at local areas and spot weld four thermocouples separated circumferentially by 90/sup 0/ at any axial distribution desired. It was found necessary to apply a nickel coating to stainless-steel-sheathed thermocouples to obtain acceptable welds. The material and shape of the inner electrode and resistance between inner and outer electrodes were found to be critical parameters in obtaining acceptable welds.

Argus Laser Fusion Facility (open access)

Argus Laser Fusion Facility

ARGUS is a two-beam Nd: glass laser system built for laser fusion irradiation experiments. It is the first glass laser system planned and built with the understanding that small-scale beam break-up is the dominant performance limiting factor in obtaining high output power. Accordingly, five vacuum spatial filters are located at strategic intervals along each chain to eliminate the accumulated small-scale filamentation. This strategy permits cascading of amplifiers to obtain a focusable output of more than one terawatt per arm in a spatially clean beam of 20 centimeter diameter. Beam diagnostics which characterize each shot include the time-integrated spatial profile and the time resolved intensity/power at the target. Demonstrated performance to date includes: (1) Peak power in excess of 2 TW at the target is achieved with regularity. (2) Maximum system brightness is in excess of 10/sup 17/ watts/cm/sup 2/ ster. (3) Shot-to-shot pointing stability within 50 ..mu.. radians is achieved over periods of days. (4) Successful target experiments have been performed with pulses of from 30 to 500 ps duration.

Assessment of the injectability of conditioned brine produced by a reaction clarification: gravity filtration system in operation at the Salton Sea geothermal field, Southern California (open access)

Assessment of the injectability of conditioned brine produced by a reaction clarification: gravity filtration system in operation at the Salton Sea geothermal field, Southern California

A Demonstration Reaction Clarifier - Gravity Filtration System with a 1600 GPM throughput capability was in operation at the joint DOE-SDG and E-MAGMA test facility located in the Salton Sea Geothermal Field, southern California, during the summer of 1979. The system, which was designed to condition spent effluent from a 10 MWe-size geothermal power plant, removes supersaturated dissolved species and residual suspended solids from brine prior to subsurface brine disposal via injection wells. The post-processing chemical stability of conditioned effluents was established by means of anaerobic incubation tests at 90/sup 0/C. The effect of residual dissolved polymer, that might be used for the purpose of scale control in upstream power plant components on the efficiency of reaction clarification, was also evaluated. Membrane filtration and core tests were used to assess the injectability of processed brine. It was found that the clarifier-filter operational procedures and system design permitted oxygenation of the brine by air intrusion. This resulted in partial stabilization of dissolved silica and precipitation of oxides of iron. As a consequence, conditioned brine injectability was poor. However, elimination of the air intrusion problem would result in a substantial improvement in brine quality. Residual amounts of dissolved polyaminoethylene (20 ppm, by …

Automated atomic absorption spectrophotometer, utilizing a programmable desk calculator

A commercial, double-beam atomic absorption spectrophotometer has been interfaced with a sample changer and a Hewlett-Packard 9810A calculator to yield a completely automated analysis system. The interface electronics can be easily constructed and should be adaptable to any double-beam atomic absorption instrument. The calculator is easily programmed and can be used for general laboratory purposes when not operating the instrument. The automated system has been shown to perform very satisfactorily when operated unattended to analyze a large number of samples. Performance statistics agree well with a manually operated instrument.

Basal Ottawa Limestone, Chattanooga Shale, Floyd Shale, Porters Creek Clay, and Yazoo Clay in parts of Alabama, Mississippi and Tennessee as potential host rocks for underground emplacement of waste

Impermeable rock units, preferably at least 500 feet thick and lying 1000 to 3000 feet below land surface, were sought in the region consisting roughly of the western /sup 3///sub 5/ths of Tennessee and the northern /sup 3///sub 5/ths of Alabama and Mississippi. All rock sequences, Cambrian through Eocene, were examined in varying detail, except the Cretaceous Selma Chalk and except the diapiric salt. These rocks were studied for their relative impermeable homogeneity, their continuity, their background of structural and seismic stability and their hydrologic associations. The Central Mississippi Ridge of north-central Mississippi is overlain by a long-stable mass of Porters Creek Clay 500-700 feet thick, in an area roughly 50-60 miles wide and about 150 miles long. The Yazoo Clay, where best developed in the west-central and southwest part of Mississippi, is in the 400-500 foot thickness range, but locally exceeds 500 feet. The entire area mapped is underlain by the Louann Salt which has produced many deep-seated salt domes and numerous piercement salt domes. Salt flow has complicated shallow structural geology throughout that area. The Chattanooga Shale rarely exceeds 60 feet in thickness in the region studied and is generally much thinner and is absent in many places. …

Basalt Waste Isolation Program: monthly report

20 square miles were mapped in the Saddle Mountains immediately north of Hanford. Twenty-six gravel pits within and adjacent to Hanford were given preliminary characterization and no tectonically induced structures were found. Approximately 1,800 wells have been identified in the Pasco Basin which penetrate basalt. In the Waste/Basalt Interaction area, progress continued in isolating those interaction products which are primary hosts for various cations and anions. Hydrologic Hole DC-5 was completed at 3,990 feet on Feb. 9. Mine modeling studies showed that at depths of 3,000 feet, the probability of joint slip above the plane of the respository is very small.

Brayton isotope power system, phase I. Final report

The Phase I program resulted in the development and ground demonstration of a dynamic power conversion system. The two key contractual objectives of 25% conversion efficiency and 1000 h of endurance testing were successfully met. As a result of the Phase I effort, the BIPS is a viable candidate for further development into a flight system capable of sustained operation in space. It represents the only known dynamic space power system to demonstrate the performance and endurance coupled with the simplicity necessary for reliable operation. This final report follows thirty-five monthly reports. For expediency, it makes liberal use of referenced documents which have been submitted to DOE during the course of the program.

Bubbles and their implications for laser-fusion (open access)

Bubbles and their implications for laser-fusion

Bubbles are concentrations of electromagnetic energy in the region of the critical density that force out the plasma to form a void. Since the critical density surface is cratered, absorption may be greater than a smooth surface since a larger area will be available for absorption and the reflected light will have a large probability of restriking the critical density. The distance between bubbles is several wavelengths and consequently they may encourage Rayleigh--Taylor instabilities. The threshold, magnetic field generation, and possible experimental evidence for bubbles are discussed. Also, the competition between sidescatter and self focusing in an entirely underdense plasma is studied and it is found that sidescatter dominates for polarization out of the simulation plane.

Calculation of resonance self shielding in $sup 235$U

Analytic and Monte Carlo calculations of the Bramblett- Czirr /sup 235/U transmission experiment STANuc!. Sci. Eng. 35, 350-357 (1969)! were performed. The numbcr of fissions from the uncollided flux could be calculated as a function of depth. The results of experiment and Monte Carlo calculations are tabulated and plotted; fission and total cross sections for /sup 235/U are shown. In view of the agreement between the analytic and Monte Carlo calculations, it appeared that the ENDF/B-III cross sections were inadequate to calculate the Czirr-- Bramblett experiment.

Calculation of two-phase dispersed droplet-in-vapor flows including normal shock waves

A method for calculating quasi-one-dimensional, steady-state, two-phase dispersed droplet-in-vapor flow has been developed. The technique is applicable to both subsonic and supersonic single component flow in which normal shock waves may occur, and is the basis for a two-dimensional model. The flow is assumed to be inviscid except for droplet drag. Temperature and pressure equilibrium between phases is assumed, although this is not a requirement of the technique. Example calculations of flow in one-dimensional nozzles with and without normal shocks are given and compared with experimentally measured pressure profiles for both low quality and high quality two-phase steam/water flow.

Calculations of fuel temperature transients in the LPTR following a main coolant system pump trip (open access)

Calculations of fuel temperature transients in the LPTR following a main coolant system pump trip

An analysis was made to determine the fuel temperature in the Livermore Pool Type Reactor, LPTR, during a transient involving a reactor scram following a cooling system pump trip. A computer code was obtained for this purpose from the University of Virginia. This code was used in preparation of UVAR-18, the SAR Manual of the University of Virginia Reactor. This reactor is very similar to the LPTR. The code incorporates a form of the reactor point kinetics equation with six delayed neutron groups, and standard heat transfer equations. The code was modified for use in this study. These modifications included rewriting the code in Fortran IV from ALGO, replacing a straight line pump coastdown by an equation closely following the actual pump RPM during a pump trip, modifying flow resistance equations to conform to the conditions in the LPTR, and replacing various constants with others applicable to the LPTR. The calculations in this study apply to a reactor scram from conditions at the ''safety limit'' settings.

Capital requirements for the transportation of energy materials: 1979 ARC estimates. Final report

TERA's estimates of capital requirements to transport natural gas, crude oil, petroleum products, and coal in the US by 1990 are presented. It is a continuation of a 1978 study (EAPA 5:3946) to perform a similar analysis on 1979 scenarios. Scenarios B, C, and D from the EIA's Mid-range Energy Forecasting Systems, as used in the 1979 Annual Report to Congress (ARC), were provided as a basis for the analysis and represent three alternative futures. Summaries of transportation investment requirements through 1990 are given for Scenarios B, C, and D. Total investment requirements for the three models (pipelines, railroads, waterways) and the three energy commodities (coal, petroleum, petroleum products, natural gas) are estimated to range between $35.3 and $42.7 billion by 1990 depending on the scenario.
