Low cost solar collector of a packed bed design

Description: Two solar collectors using a pebble bed design were constructed and tested using air as the heat exchange media. One collector had pebbles of metallurgical grade coke, and the other had a frothy volcanic material called scoria. The highly irregular surface of such vesicular material should increase the path distance for the air and the surface exposed cavities should give some honeycomb effect. Both should yield greater efficiency. Actual testing shows the efficiencies to be comparable with oth… more

High energy negative deuterium beams using double charge-exchange or surface production

Description: Experimental and theoretical research on production of negative ion beams is described. Results from a double charge-exchange experiment include 10 ms pulses of 100 ma of D/sup -/ accelerated to 60 kV. Equilibrium fractions of D/sup -/ in several metal vapors are presented. Mechanisms and measurements of D/sup -/ on surfaces are described, and a scheme is shown for producing high current, high energy beams originating on surfaces.

Coil winder for the magnet of the mirror fusion test facility

Description: A coil winder was designed for the purpose of fabricating the superconducting magnets of the Mirror Fusion Test Facility. The superconducting magnets are a displaced ying-yang pair, each having major and minor radii of 2.5 and 0.75 m, respectively, and cross section of 0.42 m by about 1.03 m. The superconductor cross section is a square, 13 mm on a side, and consists of a core of niobium-titanium embedded copper and a solid copper stabilizer. Conceptual studies made at Lawrence Livermore Labora… more

LOFT shield tank steady state temperatures with addition of gamma and neutron shielding

Description: The effect of introducing a neutron and gamma shield into the annulus between the reactor vessel and the shield tank is analyzed. This addition has been proposed in order to intercept neutron streaming up the annulus during nuclear operations. Its installation will require removal of approximately 20-/sup 1///sub 2/ inches of stainless steel foil insulation at the top of the annulus. The resulting conduction path is believed to result in increased water temperatures within the shield tank, poss… more

Samanid ceramics and neutron activation analysis

Description: Glazed pottery known as ''Afrasiyab'' and ''Nishapur'' wares (early Islamic ceramics) are generally attributed to the Samanid dynasty (819-1005). The clay composition of Samanid wares and discarded kiln items found in situ were analyzed by NAA and the elemental composition compared with that of other sherds. 7 figures, 1 table. (DLC)

Compact 80-keV neutral-beam module

Description: A compact and maintainable source of 80-keV neutral beams that focus to a high power density is required for the Mirror Fusion Test Facility (MFTF). In the new source being designed and built to meet these requirements, the cross-sectional area is reduced in two ways: by immersing the source in a vacuum where high voltage can be held over smaller distances and by redesigning grid supporting structures. Reliability is increased by reducing the electric fields everywhere else below those present … more

Regulated 15-V, 7500-A, neutral-beam filament supply

Description: Lawrence Livermore Laboratory (LLL) designed a cost-effective, regulated 15-V, 7500-A filament supply for use with the High-Voltage Test Stand , a major ERDA developmental neutral-beam test facility. The filament supply can float to 200 kV and can provide pulse widths up to 30 s. Powered by a 24-V, 0.5-TJ battery bank, it avoids the use of expensive isolation transformers and induction voltage regulators (IVR's). Battery output is regulated by a water-cooled resistor-contactor combination in wh… more

Use of gamma ray strength functions for predicting the neutron capture cross section of /sup 88/Y

Description: The present study indicates that the estimation of the gamma-ray strength function is the approach least subject to error when unmeasured capture cross sections are to be computed. An estimate is given for the /sup 88/..gamma..(n,..gamma..) cross section.

Tradeoffs in capacitor bank design

Description: When designing a capacitor bank for energy storage, the engineer should not use more capacitors, voltage, or energy than necessary to supply the load and to overcome losses. Universal curves presented here aid the designer in making intelligent choices. For example, there is a minimum stored energy to be achieved, but no minimum voltage at which to store it. Included in the curves are the effects of series losses such as voltage drops in regulator tubes or in current-limiting resistors. Capacit… more

Economic model of pipeline transportation systems

Description: The objective of the work reported here was to develop a model which could be used to assess the economic effects of energy-conservative technological innovations upon the pipeline industry. The model is a dynamic simulator which accepts inputs of two classes: the physical description (design parameters, fluid properties, and financial structures) of the system to be studied, and the postulated market (throughput and price) projection. The model consists of time-independent submodels: the fluid… more

High pressure relief valve quenching. Supplement 1

Description: In response to additional needs developed during a review of the LOFT Technical Specifications, two more pressure reduction and decontamination sump volume vs. initial temperature data points were calculated in order to adequately quench steam generator relief blowdown. The two additional points chosen were for 10,000 gallons (based on ECC requirements) and for 120/sup 0/F (NPSH limit maximum temperature). The results are that for 10,000 gallons in the sump the maximum initial temperature is 11… more

Ion exchange flowsheet for recovery of cesium from purex sludge supernatant at B Plant

Description: Purex Sludge Supernatant (PSS) contains significant amounts of /sup 137/Cs left after removal of strontium from fission product bearing Purex wastes. To remove cesium from PSS, an Ion Exchange Recovery system has been set up in Cells 17-21 at B Plant. The cesium that is recovered is stored within B Plant for eventual purification through the Cesium Purification process in Cell 38 and eventual encapsulation and storage in a powdered form at the Waste Encapsulation Storage Facility.
