Coal feeder survey for Illinois coal gasification group. [Lockhopper, Fuller Kinyon screw, Foster Miller pocket feeder]

Description: An evaluation of three coal feeder concepts (lockhopper, Fuller Kinyon screw and Foster Miller pocket feeder) for use in the ICGG first stage gasifier was made. For the sake of consistency, all feed concepts were evaluated on the same basis, that is, feeding a nominal 100 Tons per hour (TPH) against a back pressure of 50 psig. Also, all feed systems were assumed to have similar atmospheric storage hoppers and final injection systems. Accordingly, no further consideration of these support system… more

Structure and electrical activity of planar defects in EFG ribbons. First quarterly report, January 1--March 31, 1979

Description: The structure and electrical activity of planar defects in EFG Silicon was investigated by optical, electron beam induced current (EBIC), and transmission electron microscopy (TEM). What appears to be twin boundaries by both optical microscopy + etching, and by EBIC are in reality systems of microtwins, some of which are only a few atomic lattice planes thick. The electrical activity of planar defects appears to be correlated with emission of dislocations especially at termination points. Impur… more

Automating the Analytical Laboratories Section, Lewis Research Center, National Aeronautics and Space Administration: a feasibility study

Description: We studied the feasibility of computerized automation of the Analytical Laboratories Section at NASA's Lewis Research Center. Since that laboratory's duties are not routine, we set our automation goals with that in mind. We selected four instruments as the most likely automation candidates: an atomic absorption spectrophotometer, an emission spectrometer, an x-ray fluorescence spectrometer, and an x-ray diffraction unit. Our study describes two options for computer automation: a time-shared cen… more

Regional Issue Identification and Assessment program (RIIA). Environmental impacts and issues of the EIA MID-MID scenario: Federal Region I (New England)

Description: The impacts described here for 1985 and 1990 are based on a national energy projection which assumes medium energy demand and fuel supply through 1990 but does not incorporate the policies of the National Energy Act (NEA). This scenario, referred to as the Projection Series C or the TRENDLONG MID-MID scenario, is one of six possible energy futures developed by the DOE Energy Information Administration for the Department's 1977 Annual Report to Congress. It was chosen as representative of the of… more

Feasibility study of networks. Final report. [Feasibility of resource sharing via general-purpose computer networks]

Description: From July, 1974, to December, 1979, the Laboratory for Nuclear Service (LNS) conducted a study of the feasibility of resource sharing via general - purpose computer networks. Originally, the study focused on methods of implementing an ARPAnet connection for LNS in collaboration with the MIT Information Processing Center (IPC). When it appeared that the most feasible solution for LNS was to access the ARPANET via the MIT Multics system, the investigation expanded to a consideration of the implem… more

Phase 2 of the array automated assembly task for the Low Cost Solar Array Project. Quarterly report no. 6, January 1-March 31, 1979

Description: Using silk screened evaporated and sputtered Al as the metal source, the formation of Al back surface fields (BSF) was studied. The most satisfactory results were those obtained with the sputtered Al and in which open circuit voltages (V/sub oc/) of 0.585v (12 ..cap omega.. cm FZ silicon) have been achieved. The ultrasonic interconnect process is being verified. The process is generally satisfactory, but increased pull-strength may be obtained if some form of sintering is carried out on the met… more

Experimental investigation of the Trombe wall. Final report, October 1977-March 1979

Description: A variable geometry test facility was constructed and an experimental program conducted to investigate the performance characteristics of the Trombe wall, passive solar heating system. The principal objective met in the research project was the determination of representative values of wall gap thermocirculation parameters for various wall geometries. Velocity and temperature profiles in the wall gap were obtained for 2, 4, and 6-inch gap widths. Maximum values for the Grashof number under meas… more

Effects of non-uniform core flow on peak cladding temperature: MOXY/SCORE sensitivity calculations

Description: The MOXY/SCORE computer program is used to evaluate the potential effect on peak cladding temperature of selective cooling that may result from a nonuniform mass flux at the core boundaries during the blowdown phase of the LOFT L2-4 test. The results of this study indicate that the effect of the flow nonuniformity at the core boundaries will be neutralized by a strong radial flow redistribution in the neighborhood of core boundaries. The implication is that the flow nonuniformity at the core bo… more

Stochastic motion of particles in mirror machines

Description: Several applications of stochasticity theory to particle motion in quiescent mirror machines are discussed. We briefly review the problem of magnetic moment jumps in a conventional mirror machine, and point out the role of stochasticity in extending the mirror loss cone. We consider magnetic moment jumps in a flat-bottomed magnetic well, such as the solenoid of a tandem mirror machine, and find that, for suitable choices of field parameters, the magnetic moment change per bounce passes through … more

Towards unified performance measures for evaluating nuclear safeguard systems: mathematical foundations and formal comparison of existing models

Description: An important step in the analysis of large-scale systems is the development of economical and meaningful measures of system performance. In the literature on analysis of nuclear safeguard systems, many performance measures have been advanced, but their interrelationships and their relevance to overall system objectives have not received attention commensurate with the effort spent in developing detailed safeguard models. The work reported here is an attempt to improve the development and evalua… more

Cool pool development. Quarterly technical report No. 1, April-June 1979

Description: The Cool Pool is a passive cooling system consisting of a shaded, evaporating roof pond which thermosiphons cool water into water-filled, metal columns (culvert pipes) located within the building living space. The water in the roof pond is cooled by evaporation, convection and radiation. Because the water in the pool and downcomer is colder and denser than the water in the column a pressure difference is created and the cold water flows from the pool, through the downcomer and into the bottom o… more
