Standpipe-bubbler pump level-control study sodium temperature distribution (task B)

Description: A thermal analysis was performed to establish requirements for a heating system for the standpipe bubbler sufficient to maintain the sodium in the standpipe in a liquid condition over the range of operating conditions. There are very few formal requirements on operating limits or hardware selection. Therefore, consideration was given to standard types of equipment employed in a conventional manner. The recommended heating system consists of metal-sheathed resistance heaters with three units being mounted on standoffs and equally spaced around the pipe. The heaters would be covered by a layer of insulation having both interior and exterior coverings of reflective metal sheathing. The pipe temperature would be monitored by thermocouples, and the heaters would be turned on and off on a cycle of approximately 4 hours to maintain the pipe at a temperature of 800/sup 0/F +- 50/sup 0/F.

Design of a Fluorine-18 Production System at ORNL Cyclotron Facility. Part 2

Description: A fluorine-18 recovery system using an anion-exchange side-stream column was designed for the H/sub 2//sup 18/O target at the ORNL 86-inch cyclotron. The extent of radiolysis was determined and a catalyst vessel, containing a palladium catalyst, was incorporated to recombine the radiolysis product gases. The preliminary design of an externally bombarded gas target for the production of /sup 18/F/sub 2/ from /sup 18/O/sub 2/ was also completed.

Conceptual studies and preliminary design of a fluid bed fired boiler for service in an electric utility

Description: As a part of this study, B and W was to develop fluid bed system design bases and parameters using any and all sources available. The design parameters used for the fluid bed boiler designs in this study were actually developed by B and W as part of their in-house AFB development program and also as a part of the subject design study. To properly carry out the assessment portion of the work it was essential to develop an understanding of the basic interrelationship of variables in order that the final comparisons would be of consistent and realistic as possible. Inputs to meet this goal were largely based on available literature, B and W experience, and engineering judgment. In some cases we also had to venture into some theoretical development work if published results appeared incomplete. The key subject areas to be covered in subsequent pages are listed: General, Fluidizing Velocity Requirements, FBC Feed Particle Size Requirements, Calculated Slip Velocities as a Function of Particle Size and Dispersed Density, Heat Transfer Equations, Heat Transfer to Horizontal Tubes in Shallow Fluidized Beds, Combustion Efficiencies, Sulfur Capture, Freeboard Performance, Distributor Plate Design, and Economic Considerations.

Influence of lateral mass efflux on free convection boundary layers in a saturated porous medium. Technical report No. 13

Description: The effects of lateral mass efflux with prescribed temperature and velocity on vertical free convection boundary layers in a saturated porous medium at high Rayleigh numbers are studied analytically. Within the framework of boundary layer theory, similarity solutions are obtained for the special case where the prescribed temperature and velocity of the fluid vary as x/sup lambda/ and x/sup (lambda-1)/2/ respectively. The effects of mass efflux on surface heat transfer rate and boundary layer thickness are shown. Application to warm water discharge along a well or fissure to an aquifer of infinite extent is discussed.

Solar-powered irrigation systems. Technical progress report, July 1977--January 1978

Description: Dispersed solar thermal power systems applied to farm irrigation energy needs are analyzed. The 17 western states, containing 84% of nationwide irrigated croplands and consuming 93% of nationwide irrigation energy, have been selected to determine were solar irrigation systems can compete most favorably with conventional energy sources. Financial analysis of farms, according to size and ownership, was accomplished to permit realistic comparative analyses of system lifetime costs. Market potential of optimized systems has been estimated for the 17-state region for near-term (1985) and intermediate-term (2000) applications. Technical, economic, and institutional factors bearing on penetration and capture of this market are being identified.

Interim report on modeling studies of two-photon isotope separation

Description: The two-photon or two-step dissociation method of laser induced isotope enrichment is being modeled for the HBrNO photochemical system. In the model, H/sup 79/Br is selectively excited by resonance IR laser radiation and then dissociated by uv radiation. Selectively dissociated Br atoms are scavenged to form isotopically enriched BrNO and Br/sub 2/. This model includes all kinetic and absorption processes found to be significant and the time-varying concentrations of any species involved in a significant process. Among these processes are vibrational energy transfer reactions (including isotopic exchange) involving HBr v = 0 - 3, rotational and translational (velocity) relaxation processes, dissociation of HBr in the v = 0 - 3 levels, and secondary chemical reactions of the dissociation products. The absorption and kinetic processes that are most important to /sup 79/Br enrichment have been identified and the study of the effects on enrichment upon variation of external parameters (such as reactant pressure, ir or uv source intensity, and temperature) is in progress. Some preliminary results are: (1) intensity of the ir source is usually more important than the uv intensity; (2) chemical reactions are the dominant kinetic processes at lower pressures while energy transfer reactions dominate at higher pressures; (3) kinetic processes usually have greater effect on the absolute amount of enriched products; (4) isotopic abundance of /sup 79/Br in the products can range from 0.55 to 0.80 for the conditions used in the model.

Continuous liquid feed Czochralski growth. LSSA Large Area Silicon Sheet Task. Quarterly report No. 3, April--June 1978

Description: Siltec Corporation's contract with JPL is directed towards the design and development of equipment and processes, to demonstrate continuous growth of crystals by the Czochralski method, suitable for producing single silicon crystals for use in solar cells. Continuous growth is defined as the growth of 100 Kg of single silicon crystal, 10 cm in diameter, from one container. Siltec's approach to meeting this goal is to develop a furnace with continuous liquid replenishment of the growth crucible, accomplished by a meltdown system and a liquid transfer mechanism, with associated automatic feedback controls. The design of the furnace elements has been completed, and all parts are now in the fabrication stage. The electronic control console regulating the growth system and meltdown system, and the liquid transfer mechanism, has been assembled. An experiment was performed with a standard production furnace, to demonstrate controlled flow of molten silicon through a small I.D. tube by pressure differential. Sections of the transfer tube system were evaluated, power requirements to balance heat losses determined, axial temperature profile in the tube, and radial temperature gradients in the heat pack were measured. A mathematical model was made for the electromagnetic throttle valve to control flow of molten silicon through small I.D. tubes. Design parameters were derived from the model to build a working system for performance evaluation.

Basalt Waste Isolation Program: monthly report

Description: 20 square miles were mapped in the Saddle Mountains immediately north of Hanford. Twenty-six gravel pits within and adjacent to Hanford were given preliminary characterization and no tectonically induced structures were found. Approximately 1,800 wells have been identified in the Pasco Basin which penetrate basalt. In the Waste/Basalt Interaction area, progress continued in isolating those interaction products which are primary hosts for various cations and anions. Hydrologic Hole DC-5 was completed at 3,990 feet on Feb. 9. Mine modeling studies showed that at depths of 3,000 feet, the probability of joint slip above the plane of the respository is very small.
