Open Cycle Lithium Chloride Cooling System. Final Report, March 1, 1982-May 28, 1983

Description: A lithium chloride open cycle absorption chiller has been designed, built and tested. Solution reconcentration takes place in a small counter-current packed column supplied with solar heated air. Removal of non-condensable gases that enter the chiller dissolved in the strong solution and the make-up refrigerant streams is accomplished by a liquid-jet ejector and a small vacuum pump. Cooling capacities approaching 1.4 tons and COP levels of 0.58 have been achieved at non-optimum operating condit… more

Experimental evaluation of the steady state and dynamic performance characteristics of the interactive units of a coal gasification process. Quarterly report, 27 December 1982-3 April 1983

Description: A Test Plan Report has been prepared which details all the tests proposed for the 1983 operational season. One of these tests evaluates the thermal recycle mode which would be employed in a commercial configuration. In this mode, the condensate stream en route to the resaturator is passed back to the first gas cooler. The gas to liquid heat exchanger heats the condensate prior to resaturation. The analytical system simulation model, developed under this program, has been used to assess the oper… more

Detectors for high resolution dynamic pet

Description: This report reviews the motivation for high spatial resolution in dynamic positron emission tomography of the head and the technical problems in realizing this objective. We present recent progress in using small silicon photodiodes to measure the energy deposited by 511 keV photons in small BGO crystals with an energy resolution of 9.4% full-width at half-maximum. In conjunction with a suitable phototube coupled to a group of crystals, the photodiode signal to noise ratio is sufficient for the… more

A Review of Leakage-Flow-Induced Vibrations of Reactor Components

Description: The primary-coolant flow paths of a reactor system are usually subject to close scrutiny in a design review to identify potential flow-induced vibration sources. However, secondary-flow paths through narrow gaps in component supports, which parallel the primary-flow path, occasionally are the excitation source for significant vibrations even though the secondary-flow rates are orders of magnitude smaller than the primary-flow rate. These so-called leakage flow problems are reviewed here to iden… more

Simulation and Optimization Study of a Solar-Seasonal-Storage District-Heating System: The Fox River Valley Case study

Description: A central solar-heating plant with seasonal heat storage in a deep underground aquifer is designed by means of a solar-seasonal-storage-system simulation code based on the Solar Energy Research Institute (SERI) code for Solar Annual Storage Simulation (SASS). This Solar Seasonal Storage Plant is designed to supply close to 100% of the annual heating and domestic-hot-water (DHW) load of a hypothetical new community, the Fox River Valley Project, for a location in Madison, Wisconsin. Some analyse… more

Study of Chromium-Free and Chromium-Reduced Steels

Description: The goal of this study was to develop an iron-based alloy, similar to Type 316 stainless steel in mechanical and corrosion properties but with a reduced chromium content or, ideally, no chromium. A total of twenty-six 225-g ingots and ten 2.5 to 12 kg ingots of various compositions in the Fe-Si-Mn-Ni-C system were prepared. All ingots contained from 5 to 11 w/o silicon and drew their corrosion resistance primarily from this component. The composition ranges of the remaining major alloying eleme… more

Division of Biological and Medical Research Annual Technical Report 1982

Description: Computer graphic representation of the antigen-binding sites of two Bence-Jones proteins (antibody light chain diners), Loc (left) and Mcg (right). The spheres represent individual amino acids. Each binding site is composed of two variable domains and each domain consists of framework segments and the hyper-variable segments which confer the specificity to the antibody molecule.

Snubber qualification and test requirements

Description: The use of snubbers for safety related piping systems has increased significantly during the last decade. A corresponding increase in snubber requirements (criteria) has also occurred. A review of these criteria indicates inconsistencies and contradictions, and reflects how rapidly knowledge and experience has been gained and applied. This study reviews and summarizes existing criteria, illustrates inconsistencies and recommends research to resolve conflicts.

Technique for examining the fuel/cladding interface by TEM. [LMFBR]

Description: Fuel and fission-product interactions with the fuel-pin cladding is an area of concern and has been evaluated in the past principally by in-cell optical metallographic and electron-microprobe examinations. The applicability of three techniques for preparing specimens to reveal the microstructural details and local microchemistry of the fuel/cladding interface under conditions of high-resolution-scanning transmission-electron microscopy has been investigated. The specimen preparation techniques … more

Conceptual design summary for modifying Doublet III to a large dee-shaped configuration

Description: The Doublet III tokamak is to be reconfigured by replacing its indented (doublet) vacuum vessel with a larger one of a dee-shaped cross section. This change will permit significantly larger elongated plasmas than is presently possible and will allow higher plasma current (up to 5 MA) and anticipated longer confinement time. Reactor relevant values of stable beta and plasma pressure are predicted. This modification, while resulting in a significant change in capability, utilizes most of the exis… more

NOVANET: communications network for a control system

Description: NOVANET is a control system oriented fiber optic local area network that was designed to meet the unique and often conflicting requirements of the Nova laser control system which will begin operation in 1984. The computers and data acquisition devices that form the distributed control system for a large laser fusion research facility need reliable, high speed communications. Both control/status messages and experimental data must be handled. A subset of NOVANET is currently operating on the two… more

Ultra-relativistic heavy ions and cosmic rays

Description: The collisions of ultra-relativistic heavy ions, E/sub /N/ greater than or equal to 1 TeV/nucleon are most interesting, since, at these energies, matter is produced at sufficiently high energy density that a quark-gluon plasma has a good chance to form. Very heavy ions are also most interesting since the matter forms in a larger volume than for light ions, and the matter is at a somewhat higher energy density. At very high energies with very heavy ions there is great flexibility in the experime… more
