Open-cycle absorption cooling using packed-bed absorbent reconcentration

Description: The technical feasibility of a lithium chloride open-cycle absorption air conditioner using solar-heated air for reconcentration of the absorbent solution is examined. In contrast to a successfully operating Soviet design (in which absorbent reconcentration is accomplished by trickling the solution across a sloping black roof exposed to the sun), this study involves a packed-bed concentrator. Solar-heated air reconcentrates the solution by vaporizing water (the refrigerant) from the solution in… more

Electroformation of uranium hemispherical shells

Description: This effort was directed at developing an electrochemical process for forming uniform and dendrite-free deposits of uranium from molten salts. This process is to be used for the electroformation of free-standing hemispherical shells of uranium for nuclear applications. Electrodeposition of uranium onto a substrate was accomplished with a fused chloride mixture containing 42 wt% UCl{sub 3} and a fused chloride-fluoride mixture containing 4 wt % UF{sub 4}. Under pulsed potential control at 504{de… more

Multigram group separation of actinide and lanthanide elements by LiCl-based anion exchange

Description: The laboratory-scale LiCl AIX process has been successfully adapted to the multigram scale and has been used effectively in transuranium element production campaigns to separate the lanthanide fission products from the transplutonium actinides and to partition americium and curium from the heavier elements. Corrosion of the tantalum and glass equipment has been negligible. Although radiolytic gas generation has not caused a problem, radiation exposure of the Dowex 1-X10 anion exchange resin doe… more

Corrosion of type 316 stainless steel in molten LiF-LiCl-LiBr

Description: The properties of LiF-LiCl-LiBr salt make it attractive as a solvent for extracting tritium from a fusion reactor lithium blanket. Consequently, the corrosion of type 316 stainless steel by flowing (about 15 mm/s) LiF-LiCl-LiBr at a maximum temperature of 535/sup 0/C was studied to determine whether compatibility with the structural material would be limiting in such a system. The corrosion rate was found to be low (<2 ..mu..m/year) except immediately after the addition of a small amount of lit… more

Compatibility of molten salts with Type 316 stainless steel and lithium

Description: Molten salts with possible application in fusion reactors have been studied. The corrosion rate of Type 316 stainless steel in LiF--BeF/sub 2/, KNO/sub 3/--NaNO/sub 2/--NaNO/sub 3/, and LiF--LiCl--LiBr was strongly affected by the temperature and oxidation potential of the salt. A rapid exothermic reaction occurred when KNO/sub 3/--NaNO/sub 2/--NaNO/sub 3/ was melted with lithium.

Use of an open-cycle absorption system for heating and cooling

Description: Solar cooling for commercial applications using open-cycle absorption refrigeration systems has been investigated and found to be feasible. If an open-cycle absorption system can be operated as a chemical heat pump for winter heating operation, the system would offer year-round operation that could make the system economically viable for many regions of the US. An analysis of heating operation for the open-cycle system is presented using a computer program that simulates heat and mass transfer … more

Analysis of an Improved Solar-Powered Cooling System Utilizing Open-Cycle Absorbent Regeneration

Description: A solar-powered cooling system which promises high system C.O.P.'s and low collector costs is analyzed. It consists of a desiccant and an absorption cooling system operating in series to both dry and cool the air. A common solution of lithium chloride is used as the absorbant. The lithium chloride solution is regenerated by evaporating the excess water to the atmosphere in an ''open'' collector. This collector consists merely of a blackened flat surface. The weak solution of lithium chloride is… more
