Feasibility Studies of in-Situ Coal Gasification in the Warrior Coal Field. Quarterly Report
Laboratory studies on a research combustor were used in an attempt to determine the length of oxidation and reduction zones. Unfortunately the buoyant effects of the heated gases caused the burn to proceed along the upper portion of the horizontal combustor. This made the interpretation of uncertain value. Methods of measuring the thermal conductivity and chemical reactivity of coke are discussed. A bibliography of the physical and chemical properties of coke is appended. (LTN)

Selection of transition leak size for LLTR series II test A-4. [LMFBR]
The objective of this report is to provide the basis for the selection of this transition leak size for testing in the LLTR. This test, designated as Test A-4, is of particular interest because, of all the larger nonflame-jet-type-leaks, it has the longest dwell time in the vessel before the rupture disc blows, thus terminating the IHTS pressure rise. Its potential for generating secondary leaks is considered high. It is easy to postulate the generation of such a leak starting with small leak wastage and progressing into larger and larger leak sizes by self-wastage and adjacent tube wastage. On the other hand, it is not easy to postulate an instantaneous DEG failure in a properly designed and manufactured steam generator. All small leaks which are not terminated would appear to progress in stages which eventually pass through the transition size before they generate sufficient pressure to burst the rupture disc. For these reasons major emphasis is placed on the transition leak size.

Commercial solar demonstration performance evaluation report: Basking Ridge, New Jersey, Environmental Education Center
The Somerset County Park Commission for Somerset County, New Jersey, undertook the project of incorporating a solar heating, cooling, and domestic hot water system as part of its newly-constructed Environmental Education Center (EEC) located in Lord Stirling Park, Basking Ridge, New Jersey. It is the objective of this solar energy project to demonstrate the feasibility and effectiveness of using solar energy collected via 3100 sq.ft. of flat plate solar collectors to space heat, cool, and supply domestic hot water to the 18,000 sq.ft. EEC building. The project is also intended to demonstrate the aesthetics and effectiveness of incorporating an integrated solar collector array onto the roof of the newly constructed EEC facility. The results of the solar system performance for the one-year operational period are presented. (MHR)

Synthesis Gas Demonstration Plant Program, Phase I. Commercial plant conceptual design and evaluation
This volume contains the trade-off study optimizing operating pressure (1200 psig was chosen), gas purification alternatives (Rectisol and Selexol processes were chosen). Coal preparation (wet grinding in a rod mill with trommel screen removal of oversize was recommended), air quality control (a 99.65% efficiency electrostatic precipitator and Wellman-Lord sulfur dioxide removal process were recommended), and for cooling tower optimization, a cooled water temperature of 83/sup 0/F was the optimum economic choice, with a hot water entering temperature of 118/sup 0/F.

42-inch diameter producer stream gas clean-up system mathematical model
The purpose of this work is to develop a computer simulation program that will expedite the development and aid in the optimization and scale-up of the Morgantown Energy Technology Center (METC) low-Btu coal gasifier system. The gasifier system includes the METC low-Btu fixed-bed gasifier and the producer gas clean-up system. The producer Gas Clean-Up System Simulation Program, the subject of this report, develops the mathematical models and computational procedures for the material balance calculation around each of the seven major process units that constitute the METC producer gas clean-up system: gas cyclone, humidifier, electrostatic precipitator, hydrolysis unit, direct cooler, Stretford process, and final wash tower.

The Status and Development Potential of Plate-Type Fuels for Research and Test Reactors
A program of transient in-reactor experiments is being conducted by Argonne National Laboratory in the Transient Reactor Test (TREAT) facility to guide and support analyses of hypothetical core-disruptive accidents (HCDA) in liquid-metal fast breeder reactors (LMFBR). Test results provide data needed to establish the response of LMFBR cores to hypothetical accidents producing fuel failure, coolant boiling, and the movement of coolant, molten fuel, and molten cladding. These data include margins to fuel failure, the modes of failure and movements, and evidence for identification of the mechanisms which determine the failure and movements. A key element in the program is the fast-neutron hodoscope, which detects fuel movement as a function of time during experiments.

Nondestructive Evaluation Techniques for Silicon Carbide Heat-Exchanger Tubes : Annual Report, October 1977-September 1978
This report discusses the adequacy of several nondestructive evaluation techniques for the detection of flaws in silicon carbide heat-exchanger tubing. Experimental results have been obtained for conventional ultrasonic testing, acoustic microscopy, conventional and dye-enhanced radiography, holographic interferometry, infrared scanning and internal-friction measurements.
