Heavy recycle solvent studies in two-stage coal liquefaction. Final technical report, September 1, 1982-December 30, 1983

Description: The objective of this program has been to study the chemistry of the components with high boiling points in a direct coal liquefaction recycle solvent and to identify those components which lead to higher overall yields and improved product stability in the initial coal dissolution step of direct coal liquefaction processes. The major conclusions are: -454 C recycle solvent is primarily aromatic hydrocarbons (73%) and contains almost no asphaltenes; +454 C recycle solvent is primarily asphalten… more

Critical dimensions of untamped conical vessels. Revision

Description: The need often arises for determining the critical chemical concentration of uranium solution in the conical bottom of a plant reactor or storage vessel, or the dimension if the concentration is known. This report describes the mathematical analysis of Poisson's equation for a spherical sector, which approximates a right circular cone. The ratio of the critical dimension of an equivalent sphere to the height of the sector for various sector angles is derived from a comparison of first eigenvalu… more

M1-E2 mixing ratios of gamma-ground transitions in /sup 168/Er

Description: The L subshell ratios of four ..gamma..-g transitions in /sup 168/Er have been measured with the high resolution, iron, ..beta..-spectrometer at the Institut Laue-Langevin. The reduced M1-E2 mixing ratios are not consistent with the values predicted by Warner on the basis of IBA-1. It may be possible to explain the results in IBA-2 in terms of the ..delta..K = 1 mixing of the gamma-band and the pure antisymmetric states such as the 1+ isovector mode.

A technical and economic evaluation of thermal spallation drilling technology

Description: Thermal spallation of rock may be defined as a type of progressive rock failure caused by the creation of thermal stresses induced by a sudden application of heat from a high temperature source. This technology is applicable to only certain types of hard rock, such as dolomite, taconite, and granite. In 1981 and 1982, the deepest holes ever drilled by this process were drilled in granite to depths of 1086 feet and 425 feet respectively. Penetration rates at the bottom of the deeper hole reached… more

Combustion of calcium-exchanged coal. First quarterly report

Description: The work performed during this first period includes equipment modification, development of analytical methods, oxidative pretreatment runs and combustion runs. The coal feeding section of an existing furnace was modified for uninterrupted feeding and better control of residence time. Analytical methods for sulfur and calcium in the coal and ash and for gaseous SO/sub 2/ were standardized. Oxidative pretreatment experiments were conducted in a fluidized bed at temperatures about 200/sup 0/C to … more

Impact of assumptions concerning containment failure on the risk from nuclear power plants

Description: We describe the containment failure mode and release category assumptions used in the seismic risk study of the Zion nuclear power plant, which was performed by the Seismic Safety Margins Research Program (SSMRP). We then, for the dominant accident sequences, reassign containment failure modes and release categories based upon current thinking. We recalculate the seismic risk from the Zion facility using the new assumptions. Lastly, we discuss the impact of the new assumptions on the results an… more

Circuit board routing attachment for Fermilab Gerber plotter

Description: A new and potentially important method of producing large circuit boards has been developed at Fermilab. A Gerber Flat Bed Plotter with an active area of 5' x 16' has been fitted with a machining head to produce a circuit board without the use of photography or chemicals. The modifications of the Gerber Plotter do not impair its use as a photoplotter or pen plotter, the machining head is merely exchanged with the standard attachments. The modifications to the program are minimal; this will be d… more

Temperature rise in the lambertsen septum magnet associated with the positron target

Description: This note presents the results of EGS calculations and simple analytic models for the temperature rise in a spoiler, and magnet iron following such a spoiler, for a 33 GeV electron beam. Temperature rises in both spoiler and magnet iron of less than 100/sup 0/C/pulse are possible for 100..mu.. (Gaussian sigma) beams of 5 x 10/sup 10/e/sup -//pulse. The results should allow for easy optimization of spoiler thickness and spoiler-to-magnet separation distances. 3 references, 9 figures.

EQ3/6 geochemical modeling task plan for Nevada Nuclear Waste Storage Investigations (NNWSI)

Description: This task plan outlines work needed to upgrade the EQ3/6 geochemical code and expand the supporting data bases to allow the Nevada Nuclear Waste Storage Investigations (NNWSI) to model chemical processes important to the storage of nuclear waste in a tuff repository in the unsaturated zone. The plan covers the fiscal years 1984 to 1988. The scope of work includes the development of sub-models in the EQ3/6 code package for studying the effects of sorption, precipitation kinetics, redox disequili… more

AT and T Divestiture: Restructuring the U.S. Domestic Telephone Industry

Description: On January 8, 1982, the Justice Department and the American Telephone and Telegraph Company announced the settlement of the Government's seven year old antitrust suit against AT&T. Nineteen months later, in August 1983, U.S. District Court Judge Harold Greene gave final approval to the AT& T divestiture agreement. The breakup of AT&T will affect every aspect of the U.S. domestic telephone industry from the yellow pages to the manufacture of telephones. AT&T officially spun off its 22 local oper… more
