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 bei… more

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 th… more

Calculations of fuel temperature transients in the LPTR following a main coolant system pump trip

Description: An analysis was made to determine the fuel temperature in the Livermore Pool Type Reactor, LPTR, during a transient involving a reactor scram following a cooling system pump trip. A computer code was obtained for this purpose from the University of Virginia. This code was used in preparation of UVAR-18, the SAR Manual of the University of Virginia Reactor. This reactor is very similar to the LPTR. The code incorporates a form of the reactor point kinetics equation with six delayed neutron group… more

Physiopathology of blood platelets and development of platelet substitutes. Progress report, August 1, 1975--July 31, 1976

Description: Progress is reported on studies on the physiology of blood platelets in thrombocytopenic patients and rabbits. Methods for the detection of platelet antibodies and the preservation of platelets in vitro were investigated. Studies on the effect of low doses of x irradiation (up to 1000 R) on platelet function indicate that platelets exposed to ionizing radiation have increased functional activity. A list is included of publications that report the results of the studies in detail.

Synthetic-pitch binders by autoclave polymerization of organics

Description: Polymers prepared by autoclave heat treatment of simple hydrocarbons were evaluated as sources of synthetic pitches for use in fabricating composite carbons. Hydrocarbons included: indene, phenanthrene, triphenylbenzene, 1,4-diphenyl-1,3-butadiyne, and cinnamylideneindene. Autoclave temperatures and pressures were in the ranges of 340 to 515/sup 0/C and 5 to 28 MPa, respectively. The more promising pitch materials were liquids or low-melting solids with coke yields of approximately 50 weight pe… more

Apparatus for spot welding sheathed thermocouples to the inside of small-diameter tubes at precise locations

Description: Equipment and procedures used to spot weld tantalum- or stainless-steel-sheathed thermocouples to the inside diameter of Zircaloy tubing to meet the requirements of the Multirod Burst Test (MRBT) Program at ORNL are described. Spot welding and oxide cleaning tools were fabricated to remove the oxide coating on the Zircaloy tubing at local areas and spot weld four thermocouples separated circumferentially by 90/sup 0/ at any axial distribution desired. It was found necessary to apply a nickel co… more

Neutral currents and parity breakdown in atomic transitions: three proposed experiments

Description: This paper describes three proposed experiments for observing the breakdown of parity in atomic transitions due to the exchange of neutral, parity-violating currents arising from some of the new gauge models (e.g., the Weinberg model) for the weak interaction. The experiments are based on exploiting a suggestion, by Bouchiat and Bouchiat, that modern laser technology be utilized to produce intense, monochromatic, and polarized photon beams with which to excite forbidden atomic transitions of th… more

Dip coating process. Silicon sheet growth development for the large-area silicon sheet task of the low-cost silicon solar array project. Quarterly report No. 4, September 17, 1976--December 17, 1976

Description: The objective of this research program is to investigate the technical and economic feasibility of producing solar cell-quality sheet silicon by coating one surface of carbonized ceramic substrates with a thin layer of large-grain polycrystalline silicon from the melt. With the present dip coating facility, pulling rates of 5 to 7 cm/min are most likely to produce layers of the crystalline quality from which high efficiency solar cells can be fabricated. At a pulling rate of 6 cm/min, it is pos… more
