Bio-leaching of toxic metals from geothermal waste. A preliminary engineering analysis

Description: The feasibility of a biological facility to treat geothermal sludge from a base case 50-MW double-flash geothermal power plant in the Imperial Valley, California was evaluated. The effect of sludge and nutrient concentration, agitation air bubbling and sterility on the rate of metal solubilization by the bacteria Thiobacillus thiooxidans and ferrooxidans was examined. All experiments were performed in batch flasks and monitored daily for bacterial growth. T. Thiooxidans leached 36% of the zinc … more

Low cost hydrogen/novel membrane technology for hydrogen separation from synthesis gas

Description: To make the coal-to-hydrogen route economically attractive, improvements are being sought in each step of the process: coal gasification, water-carbon monoxide shift reaction, and hydrogen separation. This report addresses the use of membranes in the hydrogen separation step. The separation of hydrogen from synthesis gas is a major cost element in the manufacture of hydrogen from coal. Separation by membranes is an attractive, new, and still largely unexplored approach to the problem. Membrane … more

Analysis of Heat-Pipe Absorbers in Evacuated-Tube Solar Collectors

Description: Heat transfer in evacuated-tube solar collectors with heat-pipe absorbers is compared with that for similar collectors with flow-through absorbers. In systems that produce hot water or other heated fluids, the heat-pipe absorber suffers a heat transfer penalty compared with the flow-through absorber, but in many cases the penalty can be minimized by proper design at the heat-pipe condenser and system manifold. The heat transfer penalty decreases with decreasing collector heat loss coefficient, … more

The Reaction of Glass During Gamma Irradiation in a Saturated Tuff Environment: Part 1, SRL 165 Glass

Description: The influence of gamma irradiation on the reaction of actinide-doped borosilicate glass (SRL 165) in a saturated tuff environment has been studied in a series of tests lasting up to 56 days. The following conclusions were reached. The reaction of, and subsequent actinide release from, the glass depends on the dynamic interaction between radiolysis effects, which cause the solution pH to become more acidic; glass reaction, which drives the pH more basic; and test component interactions that may … more

Transforming Fortran DO Loops to Improve Performance on Vector Architectures

Description: The performance of programs executing on vector computers is significantly improved when the number of accesses to memory can be reduced. Unrolling Fortran DO loops, followed by substitutions and eliminations in the unrolled code, can reduce the number of loads and stores. The unrolling transformation and associated transformations of Fortran DO loops are characterized, and a set of software tools to carry out these transformations is described. The tools use the machinery available in Toolpack… more

Effect of Depth of Discharge on Lead-Acid Battery Overcharge Requirements

Description: Proper charging is essential to achieve maximum performance and life of lead-acid batteries. Excessive overcharging gives rise to increased battery temperature, gassing rates, electrolyte maintenance, and component corrosion, whereas repeated undercharging causes a gradual decrease in battery capacity, which often becomes irreversible. To develop an optimal charge procedure, the relation between battery available capacity, applied overcharge, and the depth-of-discharge (DOD) level prior to char… more

Modelling of tritium transport in a pin-type solid breeder blanket

Description: This study supplements a larger study of a solid breeder blanket design featuring lithium ceramic pins. This aspect of the study looks at tritium transport, release, and inventory within this blanket design. Li/sub 2/O and ..gamma..-LiAlO/sub 2/ are the two primary candidates for ceramic solid breeders. ..gamma..-LiAlO/sub 2/ was chosen for this blanket design due to its higher structural stability. Analysis of tritium behavior in solid breeder blankets is of great importance due to its impact … more

Model for the mechanical pellet-cladding interaction during power cycles

Description: The use of solid breeders in blanket components of fusion reactors is necessitated by the need for tritium breeding, with avoidance of problems arising from liquid metal breeders; such as corrosion and MHD pressure drop. The material 9-C (low activation equivalent of HT-9) is used for the outside structure of the module, as well as for solid breeder pin cladding. The first wall is cooled with high velocity helium through coolant channels, while the pins are cooled by helium in a cross-flow conf… more

Elastic structural analysis of the pin-type solid breeder blanket first wall

Description: A key to the successful design of a fusion blanket is the distribution of the amount of structural material in the first wall and the blanket enclosing structure. The first wall must support dynamic and static mechanical loads and at the same time sustain the thermal gradients and erosion resulting from the plasma heat and particle fluxes. Dynamic and static loads require high flexural rigidity, which is influenced by flow channels designed to cool the high heat flux incident on the first wall.… more

Description: Crystals of ((CH/sub 3/)/sub 3/SiC/sub 5/H/sub 4/)/sub 3/U are orthorhombic, Pbca, with a = 22.630(8), b = 29.177(10) and c = 8.428(3) A at 23/sup 0/C. For Z = 8 the calculated density is 1.551 g/cm/sup 3/. The structure was refined by full-matrix least-squares to a conventional R factor of 0.041 (2251 data, F/sup 2/ > 2 sigma(F/sup 2/)). The uranium atom is bonded to the three cyclopentadienyl rings in a pentahapto fashion and is in the plane of the ring centroids. The U to ring distances are … more

Environmental radiological studies downstream from the Rancho Seco Nuclear Power Generating Station, 1985

Description: Information compiled in 1985 while assessing the environmental impact of radionuclides previously discharged with aqueous releases from the Rancho Seco Nuclear Power Generating Plant is presented. In October 1984, the quantities of gamma-emitting radionuclides in water discharged to Clay Creek from the plant were reduced below operationally defined detection limits for liquid effluents. However, radionuclides previously discharged persist in the downstream environment and are found in many aqua… more

Bowing of solid breeder fuel pins and multiplier rods in a pin-type fusion blanket

Description: The most important outcome of this bowing analysis is the determination of the number of internal breeder rod supports required for good thermal performance. Although many effects were considered, the swelling deformations were the most restrictive in terms of the peak deflections. It appears that three internal supports should be sufficient to keep the rod bowing below acceptable levels without significantly raising the structure-to-breeder ratio. The most severe interaction problem involved t… more

Thermal response of a pin-type fusion reactor blanket during steady and transient reactor operation

Description: The thermal analysis of the blanket examines both the steady-state and transient reactor operations. The steady-state analysis covers full power and fractional power operation whereas the transient analysis examines the effects of power ramps and blanket preheat. The blanket configuration chosen for this study is a helium cooled solid breeder design. We first discuss the full power, steady-state temperature fields in the first wall, beryllium rods, and breeder rods. Next we examine the effects … more
