Research in radiation monitoring survey instrumentation. Final report

Description: Two low-power solid-state prototype readout units were developed, an LED display and a LCD display. This display output was in a bar-graph format, covering four-decades of information, with 10-segments per decade. The displays accept a frequency input, which is standardly available from several portable radiation-survey instruments. Both readout units will operate on two D-cell batteries (3.0 Volt), with a typical current drain requirement of 0.3 MA for the LED display and 30..mu..A for the LCD… more

Porosity of coals and coal products

Description: Different experimental approaches for characterizing porosity of coals and coal products have been described. Results of densities, surface areas and pore volume distributions for coals of different rank and the manner in which they change upon heat treatment have been discussed. True density, that is the density of the solid phase of coals, as measured by the displacement of helium, is rank dependent. It shows a shallow minimum at about 81% carbon and rises sharply as 90% carbon is approached.… more

Electric power from inertial confinement fusion: the HYLIFE concept

Description: A high yield lithium injection fusion energy chamber is described which can conceptually be operated with pulsed yields of several thousand megajoules a few times a second, using less than one percent of the gross thermal power to circulate the lithium. The concept is suitable for either lasers or heavy ion beams propagating in background gases. Because a one meter thick blanket of lithium protects the structure, no first wall replacement is envisioned for the life of the power plant. The induc… more

Civilian applications of laser fusion

Description: The commercial aspects of laser fusion were evaluated in an attempt to relate the end products (neutrons and energy) to significant commercial applications. We have found that by far the largest markets and highest payoffs for laser fusion are associated with electric power production. Hence, much of this report evaluates the prospects of producing commercial electricity with laser fusion. To this end, we have described in detail a new and promising laser fusion concept--the liquid lithium wate… more

Fusion welding of irradiated AISI 304L stainless steel tubings

Description: Fast reactor irradiated AISI 304L stainless steel tubing was fusion-welded using conventional inert gas-tungsten arc welding (GTAW) procedures which were adapted for remote operation. Metallographic examination of weld joints sometimes revealed porosity in the weld zone and cracks at the tube inner wall within the heat-affected zone. A stress analysis was performed to evaluate these defects as sites for weld failure and to establish procedures for the detection and rejection of weld joints like… more

Detailed quantum transition state theory. Application to collinear reactions

Description: The applicability of the detailed quantum transition state theory (DQTST) of Light and Siczek (J. Chem. Phys. 64, 1907(1976)) is investigated for several collinear systems. The effects of boundary conditions and the placement of the transition state surface on the DQTST predictions are considered. It is shown that the reliability of DQTST is not simply correlated with any property of the reaction path profile (barrier height or reaction exothermicity): features of the potential energy surface a… more

Summary report of TASTEX Task J: resin beam mass spectrometry for safeguards

Description: Our involvement with the TASTEX program is described in Task J; progress on this task during FY-1978 is described. This task involves collaboration with the Japanese at the Tokai reprocessing facility to evolve a sampling scheme suitable for use by International Atomic Energy Agency inspectors. The samples would be taken on resin beads and shipped in that form; because of the small quantities of material involved in this sampling technique, health hazards during transport are eliminated and cos… more

Effects of impregnation of coal with potassium and sodium salts

Description: Much interest has developed over the addition of potassium salts to potentially caking coals prior to their gasification. It is found that such addition markedly reduces the caking tendency of the coals, enabling them to be more easily handled in reactors. An extra bonus is found in that potassium is a good catalyst for both gasification of carbon in the presence of steam and the production of hydrogen via the water-gas shift reaction. In this report, mechanisms of how potassium salts may affec… more

The Overtures of Samuel Wesley

Description: Born into one of the most distinguished families in eighteenth-century England, Samuel Wesley (1766-1837) distinguished himself as a child prodigy, an ardent devotee of the music of J. S. Bach, and as a composer, performer and music lecturer. His four extant overtures, written from the year 1778 to 1824, offer an insight into his development as a composer. This edition, drawn from the Wesley manuscripts housed in the British Library, is preceded by a commentary dealing with Wesley's life, the h… more
