This report covers a two-year and seven-month solar space heating and cooling experiment conducted at the Timonium Elementary School, Timonium, Maryland. The system was designed to provide a minimum of 50% of the energy required during the heating season and to determine the feasibility of using solar energy to power absorption-type chillers for cooling. The area to be heated or cooled totaled approximately 8500 square feet of the center wing of the school. To accomplish this a system containing 5000 square feet of collectors, 5300 square feet of reflectors, a 15,000 gallon insulated hot water storage tank, 40,000 gallons of chilled water storage, an absorption chiller, miscellaneous plumbing, and instrumentation and controls, were installed. The system utilized untreated water (except for one time deionization of initial water supply) as a working fluid. The collection system efficiency (without reflectors) reached a maximum of 56% on a clear day in April 1975. This was with an average water temperature of 161/sup 0/F. The collection system efficiency (with collector and reflector area totaling 9550 square feet) on a clear day in August amounted to 40.5%. This was with an average water temperature of 170/sup 0/F. Data on the work accomplished and on the …

Information is presented on the cost effectiveness of a strategy for reducing energy consumption in buildings by combining energy conservation techniques, such as improved building design and thermal insulation with solar heating and cooling systems. It is concluded, from computer simulation studies used to determine building loads and the interaction of the solar system, that energy conservation is the most cost-effective way to save energy in all buildings at any location, and that solar systems are currently not cost-effective.

During disassembly and subsequent visual examinations of X159 (a Mark A-19A type of subassembly containing mixed-oxide fuel), 11 of 19 shroud tubes were found fully or partially severed. Several of the capsules within their shroud tubes were distinctly kinked at axial locations near those at which the shroud tubes were severed. The examination also disclosed that the shroud-tube fractures occurred during reactor operations.

Two automated reaction calorimetry systems are being constructed. The first, using a quartz thermometer probe, is essentially complete, and has been tested. The second uses a high precision digital voltmeter coupled to a microprocessor, and measures the resistance of a thermistor. The advantage of the second system lies in the small size of the temperature probe. The calorimeter systems have been used in measuring the heat of hydration of orthoesters which is a model for the steric effects in converting a tetrahedral carbon to trigonal. It has been used to measure the heat of adding trifluoroacetic acid to alkenes. This reaction is useful for the determination of the difference in heats of formation between isomeric alkenes, the heats of hydration of alkenes, and the heats of formation of secondary and tertiary alcohols. It has been used in measuring the heat evolved in adding acetic acid across strained carbon-carbon single bonds.

This report summarizes work done on reactor safety, Monte Carlo analysis of safety-related critical assembly experiments, and planning of DEMI safety-related critical experiments. Work on reactor core thermal-hydraulics is also included.

Under contract with Austral Oil Company, Eberline Instrument Corporation provided supervision and technicians to radiologically support the well plugging and site abandonment activities at the Project Rulison site during the period September 1, 1976 through October 12, 1976. The purpose of the support was to identify and prepare for removal of all radioactively contaminated materials remaining on site. The emplacement and reentry wells were successfully plugged without a serious radiological incident. There was no measurable radiation exposure above natural background to participating personnel. Decontamination and monitoring procedures assured that no equipment or material was improperly released to unrestricted use. A review of the history of project operations, the conduct of comprehensive sampling programs, and an extensive final survey, ensures that the extent of radioactivity on the site is identified and that such activity is well below established guide lines. Except for appropriate restrictions regarding deep drilling, the radiological condition of the Project Rulison site permits its return to unrestricted use.

A group of hospitals, clinics, research facilities, and medical education facilities, known as the HEAL Complex, was chosen as the site (in New Orleans) for the demonstration of a Grid-Connected Integrated Community Energy System (ICES). The contract work included a preliminary energy supply/demand assessment of the Demonstration Community, a preliminary feasibility analysis and conceptual design of a candidate Demonstration System, preliminary assessment of institutional factors, preparation of a detailed work management plan for subsequent phases of the demonstration program, firming-up of commitments from participating parties, and reporting thereon. This Phase I study has indicated that a central ICES plant producing steam, chilled water, and by-product electricity to serve the HEAL Complex is technically and economically feasible to the extent that Phase II, Detailed Feasibility and Preliminary Design, should be implemented.

The interactions of a subbituminous coal with pyridine, quinoline, piperidine, ethylenediamine, and tetrahydrofuran have been studied at temperatures ranging from 100 to 350/sup 0/C under the conditions of constant temperature contracting with pure solvent. The yields of extracted material were as high as 64.3 wt% with ethylenediamine at 250/sup 0/C on a dry, ash-free basis. The hydrogen to carbon molecular ratios in the extracts decreased with the temperature of extraction and as the yield increased and were found to be less than half that of the coal (1.01) in cases of large extracted yields. The extracted materials were generally only slightly soluble in cyclohexane or benzene, that is they consisted largely of preasphaltenes. Proton nuclear magnetic resonance studies indicated the hydrogen content of the extracted material was overwhelmingly (avg. = 88%) aliphatic. The more effective solvents were retained to a high degree in the extracted material. This fact, coupled with a hydrogen deficiency in the extract plus coal residue, suggests the formation of combinations between elements in the coal structure and solvent, accompanied by elimination of water.

Measurement of d-d neutron yields incidentally produced in multi-megawatt neutral deuterium beam injectors used in magnetic fusion experiments is discussed. Unavoidable neutron production in the neutralizer, ion-beam dump, neutral beam calorimeter and beam collimator sections of an injector is measured to provide data for the design of radiation shielding and beam diagnostic experiments. At 120 kV, 10A, 0.5s pulsed injector operation, neutron yields plateau at an instantaneous yield from the calorimeter of 10/sup 11/ n/s. Beam diagnostic applications of neutron measurements are adjustment of beam source conditions to maximize the full-energy fraction of the neutral beam on target, and measurement of density in the neutralizer.

Growth of second phase particles from a solid solution of copper-beryllium was studied to determine this alloy's suitability for acoustic emission testing. Optical and Scanning Electron microscopes were used to study the microstructure. Micro and macro hardness tests were also performed. A hardness curve for aging at 550/sup 0/F was determined. Microscopic examination revealed the presence of large inclusions which make this alloy unsuitable for the acoustic tests envisioned.

A computer code was constructed for the efficient dynamic simulation of precipitation and coarsening processes in large atom arrays. Some initial results are illustrated. (DLC)

The uniaxial stress-strain behavior of Zircaloy-2 and -4, Zircaloy-oxygen alloys with a uniform oxygen distribution, and composite specimens with a ZrO/sub 2//..cap alpha../..beta.. layer structure was investigated over the range of experimental conditions: temperature 25-1400/sup 0/C; strain rate 10/sup -6/ - 10/sup -1/ s/sup -1/; oxygen content 0.11 - 4.4 wt %; grain size 5-50 ..mu..m; texture longitudinal, transverse, and diagonal orientations; and microstructural state, which consists of the equiaxed ..cap alpha.. phase and various transformed ..beta.. acicular structures. The work-hardening and strain-rate sensitivity parameters were determined from the experimental results, and the tensile properties were correlated with oxygen concentration, oxygen distribution in the material, and microstructure. Dynamic strain-aging phenomena were observed in Zircaloy at 200, 400, and 700/sup 0/C, and superplastic deformation occurred at 850 and 1000/sup 0/C. An increase in the oxygen concentration in homogeneous Zircaloy-oxygen alloys increased the ultimate tensile strength and decreased the total strain, particularly below approximately 900/sup 0/C. In composite specimens with the ZrO/sub 2//..cap alpha../..beta.. structure, the total oxygen content had little effect on the ultimate tensile strength below approximately 1000/sup 0/C, but the strength increased with oxygen content at higher temperatures. Information on the effects of grain size, oxygen content, texture, and …

Detailed results are presented.

The laser resonance absorption technique has been used to determine the relaxation rate of electronically excited neodymium vapor during its expansion into vacuum. Significant increases of population into ground and 1128 cm/sup -1/ levels were found. Analysis shows that interaction between excited metastable atoms and electrons are much more important for relaxation than atom-atom collisions. The final population of neodymium appears to be frozen at a temperature lower than the surface temperature of melt.
