Project for laboratory study for removal of organic sulfur from coal. Quarterly technical progress report

Description: The Gravimelt Process was extended to the desulfurization of ordinary mine-cleaned Kentucky No. 11 coal obtained from the Tennessee Valley Authority. Eight process runs were made resulting in reduction of the sulfur content from a starting 2.7 lbs S/10/sup 6/ Btu to a mean of 0.475 lbs S/10/sup 6/ Btu, (0.95 lbs SO/sub 2//10/sup 6/ Btu) for an average 82% sulfur reduction. The effect of utilization of molten sodium hydroxide alone vs molten mixed potassium and sodium hydroxide was investigated … more

HEDL contribution to Office of Nuclear Waste Isolation. July through September quarterly report: spent fuel characterization equipment

Description: Progress reports are presented for the following areas of study: spent fuel characterization equipment; spent fuel characterization; and spent fuel/package performance. Some of the highlights are: calorimetry was performed on spent fuel assemblies D15 and D22 which were destined for packaging and emplaced into the Climax-Spent Fuel Test (C-SFT); review and analysis of the destructive examination data on five fuel rods pulled from the C-SFT assemblies is continuing; under the disposal condition … more

Picosecond x-ray measurements from 100 eV to 30 keV

Description: Picosecond x-ray measurements relevant to the Livermore Laser Fusion Program are reviewed. Resolved to 15 picoseconds, streak camera detection capabilities extend from 100 eV to higher than 30 keV, with synchronous capabilities in the visible, near infrared, and ultraviolet. Capabilities include automated data retrieval using charge coupled devices (CCD's), absolute x-ray intensity levels, novel cathodes, x-ray mirror/reflector combinations, and a variety of x-ray imaging devices.

Peat biogasification development program. Quarterly progress report No. 4, July 1-September 30, 1980

Description: During this reporting period preliminary data were taken for the kinetic models necessary for a peat biogasification process. A limited number of batch experiments were conducted to obtain rate data for the solubilization kinetic model. The analysis of the pretreatment batch tests was slowed down this quarter because the High Pressure Liquid Chromatography (HPLC) solvent system was altered. This was done because a mass balance around the HPLC with the solvent system (85% H/sub 2/O/15% acetonitr… more

Process development for automated solar cell and module production. Task 4. Automated array assembly. Quarterly report No. 1

Description: Work has been divided into five phases. The first phase is to modify existing hardware and controlling computer software to: (1) improve cell-to-cell placement accuracy, (2) improve the solder joint while reducing the amount of solder and flux smear on the cell's surface, and (3) reduce the system cycle time to 10 seconds. The second phase involves expanding the existing system's capabilities to be able to reject broken cells and make post-solder electrical tests. Phase 3 involves dev… more

Effects of minerals on coal-beneficiation processes. Quarterly report No. 10, January 1-March 31, 1980

Description: All basic data acquisition relevant to characterization of the contract samples physically and chemically has been completed. Assessment of this data and inter-relationships with mineralogical characterization data is concurrently on-going, with final petrographic data acquisition for the contract to be affected during the next quarter. This remaining analytical work is the detailed maceral analysis of the Illinois No. 6 samples. Work during this quarter focused on coarse and fine coal heavy-me… more

Overall requirements for an advanced underground coal extraction system

Description: This report presents overall requirements on underground mining systems suitable for coal seams exploitable in the year 2000, with particular relevance to the resources of Central Appalachia. These requirements may be summarized as follows: (1) Production Cost: demonstrate a return on incremental investment of 1.5 to 2.5 times the value required by a low-risk capital project. (2) Miner Safety: achieve at least a 50% reduction in deaths and disabling injuries per million man-hours. (3) Miner Hea… more

Investigation of polarized-proton target materials by differential calorimetry: preliminary results

Description: A simple differential calorimeter was designed and operated for an investigation of the thermodynamic properties of polarized target materials. The calibration and use of the calorimeter are discussed, after a brief exposition of our motivation for this work. The results of a preliminary study of target materials is presented with emphasis on the relevance of the glass state to dynamic polarization in chemically-doped targets.
