Design of a System using CPC Collectors to Collect Solar Energy and to Produce Industrial Process Steam

Design of a System using CPC Collectors to Collect Solar Energy and to Produce Industrial Process Steam

Date: August 1979
Creator: Argonne National Laboratory. Solar Energy Group.
Description: A system has been designed to use CPC collectors to collect solar energy and to generate steam for industrial process heat purposes. The system is divided into two loops with the collectors in the collector loop to operate a pre-heater and the collectors in the boiler loop to heat water to elevated pressures and temperatures. A flash boiler is used to throttle the heated water to steam. Two types of CPC collectors are chosen. In the collector loop the CPC collectors are fitted with concentric tube receivers. In the boiler loop the collectors employ heat pipes to transmit heat. This design is able to alleviate the scaling and plumbing problems. A fragile receiver tube can also be employed without rupture difficulties. The thermal processes in the collectors were analyzed using a computer modeling. The results were also used to develop a thermodynamic analysis of the total system. Calculations show that the design is technically feasible. The CPC collector is shown to have an efficiency that is very weakly dependent on its operating temperatures, which makes the collector particularly attractive in high temperature applications.

Feasibility of Underground Storage/Disposal of Noble Gas Fission Products

Feasibility of Underground Storage/Disposal of Noble Gas Fission Products

Date: August 1979
Creator: Winar, R. M.; Trevorrow, L. E. & Steindler, M. J.
Description: The quantities of krypton-85 that can be released to the environment from nuclear energy production are to be limited after 1983 by Federal regulations. Although procedures for collecting the krypton-85 released in the nuclear fuel cycle have been developed to the point that they are commercially available, procedures for terminal disposal of the collected gas are still being examined for their feasibility. In this work, the possibilities of underground disposal of krypton-85 by several techniques were evaluated. It was concluded that (1) disposal of krypton-85 as a solution in water or other solvents in deep wells would have the major disadvantages of liquid migration and the requirement of extremely large volumes of solvent; (2) disposal as bubbles entrained in cement grout injected underground presents the uncertainty of gaseous migration through permeable solid grout; (3) disposal by injection into abandoned oil fields would be favored by solubility of krypton in residual hydrocarbons, but has the disadvantages that such fields contain numerous shafts offering avenues of escape and also that the fields may be reworked in the future for their hydrocarbon residues; (4) underground retention of krypton-85 injected as a gas may be promising, given the right lithology, through entrapment in interstices ...

Multichannel Clad-Relocation Model for Fast-Reactor Loss-of-Flow Accidents

Multichannel Clad-Relocation Model for Fast-Reactor Loss-of-Flow Accidents

Date: August 1979
Creator: Ishii, M.; Chen, W. L. & Grolmes, M. A.
Description: During an unprotected undercooling accident in a liquid-metal fast breeder reactor, the motion and relocation of the molten cladding can he important because of its potentially significant effect on reactivity, blockage formation, and subsequent fuel motion. The present study analyzes the clad relocation problem1 based on a multichanneI film-flow model. The important aspects considered in the analysis are the nonuniform transverse ci1ad-melting pattern and diversions of sodium vapor flow within a subassembly. It has been shown that the motion of molten clad and subsequent blockage formations can be significantly influenced by this interconnected channel effect. Several sample cmi cu lat ions have been made in order to demonstrate these points.

Recovery of Actinides from TBP-Na₂CO₃ Scrub-Waste Solutions: the ARALEX Process

Recovery of Actinides from TBP-Na₂CO₃ Scrub-Waste Solutions: the ARALEX Process

Date: August 1979
Creator: Horwitz, E. P.; Bloomquist, C. A. A.; Mason, G. W.; Leonard, R. A. & Ziegler, A. A.
Description: A flow-sheet for the recovery of actinides from TBP-Na2CO3scrub-waste solutions has been developed, based on batch extraction data, and tested, using laboratory-scale countercurrent extraction techniques. The process, called the ARALEX process, uses 2-ethyl-1-hexanol (2-EHOH) to extract the TBP degradation products (HDBP and H/sub 2/MBP) from acidified Na2CO3scrub waste leaving the actinides in the aqueous phase. Dibutyl and monobutyl phosphoric acids are attached to the 2-EHOH molecules through hydrogen bonds, which also diminish the ability of the HDBP and H2/MBP to complex actinides. Thus all actinides remain in the aqueous raffinate. Dilute sodium hydroxide solutions can be used to back-extract the dibutyl and monobutyl phosphoric acid esters as their sodium salts. The 2-EHOH can then be recycled. After extraction of the acidified carbonate waste with 2-EHOH, the actinides may be readily extracted from the raffinate with DHDECMP or, in the case of tetra- and hexavalent actinides, with TBP. The ARALEX process can also be applied to other actinide waste streams which contain appreciable concentrations of polar organic compounds (e.g., detergents) that interfere with conventional actinide ion exchange and liquid-liquid extraction procedures.

The Wetting Behavior of Molten-Chloride Electrolytes: Capillarity Effects in Lithium-Aluminum/Metal Sulfide Batteries

The Wetting Behavior of Molten-Chloride Electrolytes: Capillarity Effects in Lithium-Aluminum/Metal Sulfide Batteries

Date: August 1979
Creator: Eberhart, James G.
Description: A lithium-aluminum/iron sulfide battery which uses a molten LiCl-KCl electrolyte is presently under development at Argonne National Laboratory. The performance and lifetime of this electrochemical system depend, in part, on the ability of the electrolyte to wet the materials used as electrodes, separators, and particle retainers. For this reason contact-angle measurements were made on smooth, 100%-dense surfaces of the cell materials. In addition, electrolyte penetrability determinations were made on the porous materials actually used as cell separators and particle retainers. The results of these measurements led to techniques for completely filling porous cell components with electrolyte, suggestions for dealing with the problem of electrolyte creeping, estimates of the likelihood of electrolyte transfer from one porous component to another, and estimation of the maximum allowable vertical cell dimensions.

Fission-Product Releases to the Primary System of EBR-II from April 1977 to May 1978

Fission-Product Releases to the Primary System of EBR-II from April 1977 to May 1978

Date: July 1979
Creator: So, B. Y. C.; Gross, K. C.; Lambert, J. D. B.; Kim, F. S.; Ebersole, E. R. & Lang, M. T.
Description: Suspected fission-product releases from 18 subassemblies between April 1977 and May 1978 are presented. Post-irradiation examinations pm 15 of the suspect subassemblies confirmed that all contained one or more breached elements. Except for two untagged subassemblies, xenon tagging was the primary method of identification, although other methods were used where appropriate. Methods to monitor and identify fission product sources are discussed. Problems encountered elements on plant availability were minimal during this reporting period. From all evidence, cladding breaching on elements in EBR-II continues to be a benign process.

Plastic Heat Exchangers : A State-of-the-Art Review

Plastic Heat Exchangers : A State-of-the-Art Review

Date: July 1979
Creator: Miller, David; Holtz, Robert E.; Koopman, R. Nelson; Marciniak, Thomas J. & MacFarlane, Donald R.
Description: Significant increases in energy utilization efficiency can be achieved through the recovery of low-temperature rejected heat. This energy conserving possibility provides incentive for the development of heat exchangers which could be employed in applications where conventional units cannot be used. Some unique anticorrosion and nonstick characteristics of plastics make this material very attractive for heat recovery where condensation, especially sulfuric acid, and fouling occur. Some of the unique characteristics of plastics led to the commercial success of DuPont's heat exchangers utilizing polytetrafluoroethylene (trade name Teflon) tubes. Attributes which were exploited in this application were the extreme chemical inertness of the material and its flexibility, which enabled utilization in odd-shaped spaces. The wide variety of polymeric materials available ensures chemical inertness for almost any application. Lower cost, compoundability with fillers to improve thermal/mechanical properties, and versatile fabrication methods are incentives for many uses. Also, since many plastics resist corrosion, they can be employed in lower temperature applications (< 436 K), where condensation can occur and metal units have been unable to function. It is clear that if application and design can be merged to produce a cost-effective alternate to present methods of handling low-temperature rejected heat, then there is significant incentive ...

Review of Sodium Effects on Candidate Materials for Central Receiver Solar-Thermal Power Systems

Review of Sodium Effects on Candidate Materials for Central Receiver Solar-Thermal Power Systems

Date: July 1979
Creator: Chopra, O. K.; Wang, J. Y. N. & Natesan, K.
Description: Available information on the corrosion behavior and mechanical properties of structural materials in a high-temperature sodium environment has been reviewed to compile a data base for selection of materials for advanced central-receiver solar-power systems, for which sodium is being considered as a heat-transfer fluid and thermal-storage medium. Candidate materials for this application (e.g., Types 304, 316, and 321 stainless steel, Alloy 800, and Fe-2 1/4 Cr-1Mo and Fe-9Cr-1Mo ferritic steels) have been used in the construction of various components for liquid-metal fast-breeder reactors in this country and abroad with considerable success. Requirements for additional information on material properties in a sodium environment are identified. The additional data coupled with more quantitative deformation models, failure criteria, and component design rules will further reduce uncertainties in the assessment of performance limits and component reliability in large sodium heat-transport systems.
