People born into a particular social group inherit that social network and act more or less in accord with it, and so inherit the effects of its sin. Network or other of social relations that are not as God intends. In the course of biological and social evolution, any group of creatures capable of any degree of relationship to God that fails to be properly related to God commensurate with their stage of development-any such group will have some 76 figures, 8 tables.“The story of Adam and Eve, as used by the Eastern church to account for our inherited weakness to withstand temptation as an effect of Adam and Eve's sin, can fruitfully be understood today without a historical Adam and Eve but instead with an evolutionary and social understanding of human beings. These revisions included additional penetrations in the burner tube side-wall for above-bed fines recycle, replacement and deletion of several metal bellows with bellows of more reliable design, and improvements in designs for burner alignment and feeder mechanisms. The successful completion of the tests was due, in part, to implementation of significant equipment revisions which were suggested by both the initial 0.40-m system tests and by results of ongoing development work on the 0.2-m primary burner. Again, such operation had never been completed on the 0.20-m system from which the 0.40-m burner was scaled.
Efficient combustion of graphite fines using the pressurized recycle technique was demonstrated throughout the long-duration operation required to reduce a high carbon fresh feed bed to a low carbon particle bed. Such clusters had never been fed to the 0.20-m system. The 0.40-m perforated conical gas distributor, scaled up from the 0.20-m more » primary burner, has proven reliable in safely burning even the largest, densest adhered graphite/fuel particle clusters originating from the crushing of loaded fuel elements. The 0.40-m system operation is followed from its first short heatup test in September 1976 to a > 40-h burning campaign that processed 20 LHTGR blocks in September 1977. This report documents the successful long-term operation of the 0.40-m primary burner in burning crushed fuel elements. This burning process requires combustion of beds containing both large particles and very dense particles, and also of fine graphite particles which elutriate from the bed. « lessįluidized bed combustion is required in reprocessing the graphite-based fuel elements from high-temperature gas-cooled reactor (HTGR) cores. A detailed calculation of spent fuel compositions by fuel block and particle type is being performed for better definition of process streams in a fuel reprocessing facility. These runs represented the first cycle and second uranium cycle of the acid-Thorex flowsheet. Eight solvent extraction runs were completed during the quarter. Bench-scale tests on oxidation of HTGR fuel boron carbide at 900/sup 0/C indicates that most if not all of the carbide will be converted to boron oxide in the fluidized bed burner. Two-stage leaching runs with burned-back ThC/sub 2/ indicate there are no measurable differences in total dissolution time as compared to single-stage leaching. Only minor effects were observed and reference values for facility operations were specified. Twelve leaching runs were performed during the quarter using crushed, burned-back TRISO coated ThC/sub 2/ particles and burned-back BISO coated sol gel ThO/sub 2/ particles to examine the effect of varying the Thorex-to-thoria ratio to give product solutions ranging from 0.25M to 1M in thorium. Experimental work on the 20-cm more » primary fluidized bed burner verified the fines recycle operating mode in runs of greater than 24 hr. Studies of flow characteristics of granular solids in pneumatic transfer systems are continuing and data are being collected for use in design of systems for solids handling. Fabrication and receipt of all major components is under way, and auxiliary instrumentation and support systems are being installed. Design work on the multistage crushing system, the primary and secondary fluidized bed burners, the pneumatic transfer systems, and the ancillary fixtures for semiremote assembly and disassembly is essentially complete. The development program for HTGR fuel reprocessing continues to emphasize the design and construction of a prototype head-end line.
