1,4-diphenylbutadiyne as a potential tritium getter
Research on the acetylene compound 1,4-diphenylbutadiyne is an effort to develop an air-operative tritium gas scavenger. T/sub 2/ adds to the acetylene bond of the organic in the presence of a metal catalyst. The catalyst also stimulates the oxidation reaction as well. The butadiyne compound has shown good reaction efficiency at 300 ppM T/sub 2/ in static dry air. At this concentration 75% of the scavenged tritium was in the organic. This work has expanded to the investigation of liquid acetylenes, metal acetylene complexes, organometallics and acetylene based alcohols. The best of these compounds has gettered 100% of 10 to 500 ppM T/sub 2/ for both static and dynamic air flow conditions.

10-MWe solar-thermal central-receiver pilot plant, solar-facilities design integration: system integration laboratory test plan (RADL item 6-4)
A general demonstration test plan is provided for the activities to be accomplished at the Systems Integration Laboratory. The Master Control System, Subsystem Distributed Process Control, Representative Signal Conditioning Units, and Redline Units from the Receiver Subsystem and the Thermal Storage Subsystem and other external interface operational functions will be integrated and functionally demonstrated. The Beckman Multivariable Control Unit will be tested for frequency response, static checks, configuration changes, switching transients, and input-output interfaces. Maximum System Integration Laboratory testing will demonstrate the operational readiness of Pilot Plant controls and external interfaces that are available. Minimum System Integration Laboratory testing will be accomplished with reduced set of hardware, which will provide capability for continued development and demonstration of Operational Control System plant control application software. Beam Control System Integration Laboratory testing will demonstrate the operational readiness of the Beam Control System equipment and software. (LEW)

9519 biotite granodiorite reacted in a temperature gradient
A biotite granodiorite from the Fenton Hill Hot Dry Rock (HDR) geothermal system was reacted in a controlled temperature gradient with initially distilled water for 60d. Polished rock prisms were located in the gradient at 72, 119, 161, 209, 270, and 310/sup 0/C. Scanning electron microscope and microprobe analyses show the appearance of secondary phases: Ca-montmorillonite at 72/sup 0/C and 119/sup 0/C; zeolite, either stilbite or heulandite, at 161/sup 0/C; and another zeolite, thomsonite, at higher temperatures. Solution analyses show a steady state equilibrium exists between solution and overgrowths after about 2 weeks of reaction. The chemographic relations for the system are explored in some detail indicating the divariant assemblages may be placed in a reasonable sequence in intensive variable space. These relations predict high and low temperature effects not directly observed experimentally as well as relevant univariant equilibria. Solution chemistry indicates the Na-Ca-K geothermometer more adequately predicts temperature in this system than does the silica geothermometer.

Acoustic Emission Under Biaxial Stresses in Unflawed 21-6-9 and 304 Stainless Steel
Acoustic emission (AE) testing has been carried out with uniaxial and biaxial (2:1 stress ratio) stressing of smooth samples of 21-6-9 and 304 stainless steel (SS). Uniaxial testing was done with simple tensile and compression samples as well as with the special biaxial specimens. Biaxial tensile stressing was accomplished with a specially designed specimen, which had been used previously to characterize AE in 7075 aluminum under biaxial stressing. Results were obtained for air-melt and for vacuum-melt samples of 21-6-9 SS. The air-melt samples contain considerably more inclusion particles than the vacuum-melt samples. For the 304 SS, as received material was examined. To allow AE correlations with microstructure, extensive characterization of the 21-6-9 microstructure was carried out. Significant differences in AE occur in biaxially stressed specimens as compared to uniaxially stressed samples. 15 figures, 3 tables.

The thorium or uranium metallocycles, [(Me{sub 3}Si){sub 2}N]{sub 2} ~ MCH{sub 2}Si(Me){sub 2}NSiMe{sub 3} (I), react with tert-butylcyanide to give the six~membered ring compounds, [(Me{sub 3}Si){sub 2}N]{sub 2}MN=C(t-Bu)CH{sub 2}SI(Me){sub 2}N- SiMe{sub 3}. The metallocycles (I) also react with the isoelectronic molecules tert-butylisocyanide and carbon monoxide to give the unique five~membered ring compounds with exocyclic carbon-carbon double bonds, [(Me{sub 3}Si){sub 2}N]{sub 2}MXC (=CH{sub 2})Si (Me){sub 2}NSiMe{sub 3} , where X is t-BuN or oxygen. The four-membered ring metallocycles (I) give simple coordination complexes of the type [ (Me{sub 3}Si){sub 2}N]{sub 2}MCH{sub 2}Si (Me){sub 2}NSiMe{sub 3}-(N{sub 3}SiMe{sub 3}) with trimethylsilylazide.

Advanced system demonstration for utilization of biomass as an energy source
The results of the study investigations confirm the feasibility of collecting 1000 oven dry tons of biomass per day to fuel a 510,000 lb/hr boiler operating in a congeneration mode and producing steam and electricity. This study was based on the supply of a significant portion of the facility's biomass fuel by tree harvesting and collection operations within a 50 mile radius of the plant site. These operations, including transporting biomass to the conversion plant, would pose no threat to the environment if good forestry practice is carefully maintained. Other environmental factors relating to air and water discharges from the conversion plant pose no significant technological problems in complying with federal, state, and local regulations at a cost that is competitive with similar costs associated with fossil fueled facilities.
