Advanced Selenide Thermoelectric Development Program. Final Report

Description: The primary objective of this work was to demonstrate that copper silver selenide and TAGS could be segmented. The hot junction temperature was planned to be 725/sup 0/C with the segmentation temperature at 400/sup 0/C, both temperatures were selected to prevent excessive sublimation from the hot ends of the segments, respectively. The program was planned as a cooperative effort between General Atomic company and Teledyne Energy Systems. Accordingly, General Atomic synthesized the CuAgSe that w… more

Calibration of a neutron log in partially saturated media. Part II. Error analysis

Description: Four sources or error (uncertainty) are studied in water content obtained from neutron logs calibrated in partially saturated media for holes up to 3 m. For this calibration a special facility was built and an algorithm for a commercial epithermal neutron log was developed that obtains water content from count rate, bulk density, and gap between the neutron sonde and the borehole wall. The algorithm contained errors due to the calibration and lack of fit, while the field measurements included u… more

Coal materials handling coal feeder development, Phase I. First quarterly technical progress report, October-December 1980

Description: The FMA Linear Pocket Feeder (LPF) is a positive displacement feed system in which the pressure seal is developed by a set of mechanical labyrinth seals between the piston rings and the sealing tube. The pressure seal is completely independent of the type and size of coal used. The LPF can maintain a pressure difference with no coal in the system and can achieve steady state operation in less than a minute after startup. Coal flow rate can be changed while the LPF is operating at design speed a… more

Contract WEC 3. 2. 3 study to optimize Cr-Mo steels to resist hydrogen and temper embrittlement. Quarterly report No. 9, second annual report, January 1-December 31, 1980

Description: The hydrogen embrittlement susceptibility of commercial 2-1/4 Cr-1Mo steels has been investigated, using H/sub 2/S as the primary environment. After it was found that low strength steels, which had been given a post weld heat treatment, were immune to the test techniques developed, the effect of strength level was studied to establish a lower limit for embrittlement. Similar tests on the peak hardness zone in the heat affected zone of a weld showed that the crack preferred to move to the far he… more

Development and manufacture of a Nb/sub 3/Sn superconductor for the high-field test facility

Description: The High-Field Test Facility (HFTF) project has two primary goals. The first is to establish manufacturing capability for a Nb/sub 3/Sn conductor suitable for use in a mirror fusion coil. The second is to provide a test facility for evaluating other fusion conductor designs at high fields. This paper describes some of the problems encountered and the solutions devised in working toward the first goal. Construction of the test facility coils will be described in a subsequent paper.

Effect of non-adiabaticity of alpha particles in the axisymmetric cusp TMR

Description: One of the end plug configurations we have investigated for use in a tandem mirror reactor is the axisymmetric cusp. We show that because of non-adiabaticity, the containment of 3.5 MeV alpha particles in this configuration is insufficient for the attainment of acceptable plasma performance.

Elimination of output-current transients in the MFTF sustaining neutral-beam-arc power supplies

Description: The twenty-three (23) MFTF sustaining neutral beam arc power supplies were designed to provide 0.3 to 30 second output pulses over a range of 24 to 71 volts and 600 to 4000 amperes at 10 percent duty. For economic reasons, the circuit design consists of a 12 pulse rectifier which is asynchronously switched on and off by a three phase electromechanical contactor in the primary ac input. The paper describes the analysis of the problem, various possible solutions considered, and the simple and ine… more

Experimental and theoretical study of flame inhibition by bromine-containing compounds

Description: The present paper represents the first effort to date in which a combined experimental and theoretical approach has been used to study the effects of several inhibitors on hydrocarbon-air flames. This work is part of an attempt to build a consistent picture of chemical kinetic flame inhibition, beginning with a simple halogen molecule such as HBr and progressing sequentially towards more complex and more practical inhibitors such as CF/sub 3/Br. Inhibition efficiency can be defined as the rate … more

Formation of negative hydrogen ions in surface and volume processes

Description: The backscattering of energetic hydrogen particles, 1-1000 eV, from alkali metal surfaces provides for a relatively large yield of negative hydrogen ions. These yields are enhanced by particle reflection from surfaces consisting of partial alkali coatings over high-Z transition-metal substrates. The theoretical data supporting these observations are reviewed. The parameters leading to optimum reflection yields are summarized. In the volume of a hydrogen discharge with electron temperatures of a… more

Framework for Evaluating the Effectiveness of Nuclear-Safeguards Systems. [Aggregated Systems Model (ASM)]

Description: This paper describes an analytical tool for evaluating the effectiveness of safeguards that protect special nuclear material (SNM). The tool quantifies the effectiveness using several measures, including probabilities and expected times to detect and respond to malevolent attempts against the facility. These measures are computed for a spectrum of threats involving outsiders, insiders, collusion, falsification, and deceit. Overall system effectiveness is judged using performance indices aggrega… more
