Dispersed solar thermal power systems applied to farm irrigation energy needs are analyzed. The 17 western states, containing 84% of nationwide irrigated croplands and consuming 93% of nationwide irrigation energy, have been selected to determine were solar irrigation systems can compete most favorably with conventional energy sources. Financial analysis of farms, according to size and ownership, was accomplished to permit realistic comparative analyses of system lifetime costs. Market potential of optimized systems has been estimated for the 17-state region for near-term (1985) and intermediate-term (2000) applications. Technical, economic, and institutional factors bearing on penetration and capture of this market are being identified.

The report summarizes the Light Duty Vehicle Fuel Consumption Model developed for the Office of Conservation and Advanced Energy Systems Policy in the Department of Energy. The purpose of the model is to estimate annual passenger auto (PA) and non-passenger auto (NPA) fuel consumption through 1986. The model is intended to: (1) provide information on future estimated petroleum demand for the majority of the US transportation sector; and (2) generate a better understanding of the trends in fuel consumption in light of fuel economy standards issued by the Department of Transportation (DOT) under the Energy Policy and Conservation Act of 1975 (EPCA). The model also is designed to provide disaggregated data for PA's and NPA's in order to anayze their relative importance in estimating total fuel consumption and to calculate the proportion of diesel, leaded, and unleaded fuels in total fleet consumption.

A stress analysis has been completed for the LOFT piping nozzles penetrating through the containment vessel in accordance with the 1965 edition of Section III of the ASME Boiler and Pressure Vessel Code. LOFT Specification S-1 states that the 1965 edition, including the addenda through the summer 1966 issue, be used. Stresses in the containment wall and in the nozzles result from mechanical and thermal loads on the piping that penetrate the nozzles. The mechanical loads were compiled in LTR 1217-7 and the temperature gradients were provided by the Thermal Analysis Branch. This analysis indicates that the nozzles and the containment wall are adequate to sustain the given mechanical and thermal loads. Therefore, it is recommended that paragraph number S1-04, section M of LOFT specification S-1 be revised to list the nozzle loads presented in Table 3, page A-3a. 9 refs.

Volume II of the First Semiannual Report of the Rocky Flats Small Wind Systems Test Center (WSTC) describes the nine (9) small wind energy conversion systems (SWECS) tested as of June 30, 1978 and provides the significant quantitative and qualitative data collected to that date. Meteorological data collected at Rocky Flats are also provided and described.

As a part of this study, B and W was to develop fluid bed system design bases and parameters using any and all sources available. The design parameters used for the fluid bed boiler designs in this study were actually developed by B and W as part of their in-house AFB development program and also as a part of the subject design study. To properly carry out the assessment portion of the work it was essential to develop an understanding of the basic interrelationship of variables in order that the final comparisons would be of consistent and realistic as possible. Inputs to meet this goal were largely based on available literature, B and W experience, and engineering judgment. In some cases we also had to venture into some theoretical development work if published results appeared incomplete. The key subject areas to be covered in subsequent pages are listed: General, Fluidizing Velocity Requirements, FBC Feed Particle Size Requirements, Calculated Slip Velocities as a Function of Particle Size and Dispersed Density, Heat Transfer Equations, Heat Transfer to Horizontal Tubes in Shallow Fluidized Beds, Combustion Efficiencies, Sulfur Capture, Freeboard Performance, Distributor Plate Design, and Economic Considerations.

This LTR presents the general basic engineering facts related to an open phase fault in a three phase power system commonly referred to as a single phase condition. It describes the probable results to electrical motors and describes the LOFT system design factors which minimize the likelihood of such a fault occurring at LOFT. It recognizes that the hazard of such a fault is a realistic threat and notes the types of relays designed to provide protection. Recommendations are made to perform a detailed engineering study to determine the most advantageous protective relay design, and to implement such a design by installation of the necessary devices and controls.

The Combined Electrolysis Catalytic Exchange system was operated to experimentally determine mass transfer coefficients and to test the process controller. Values for H/sub OG/ and K/sub tilde y/a were obtained at three separate molar flow ratios (tilde L/tilde G). Replicate values of K/sub tilde y/a from additional runs agreed with initial results to within 16%. Two process controller tests were completed that demonstrated the reliability of the system hardware and the feasibility of the digital controller software. The feasibility of using a xenon flashlamp source in the uv photodissociation step of the two-photon water-hydrogen laser isotope separation (LIS) process has been demonstrated with H/sub 2/O/D/sub 2/ and D/sub 2/O/H/sub 2/ photocatalyzed exchange experiments. A nearly 10 : 1 isotopic selectivity between the photodissociation of ground state H/sub 2/O and D/sub 2/O was observed with an unfiltered xenon flashlamp source. The effectiveness of the hydrogen scavenger system was also demonstrated in these experiments. Tests continued on samples of cement and cement-plaster mixtures which were injected with tritiated water, cured, and then impregnated with catalyzed styrene monomer. After polymerization the samples were put into uncontaminated water and the tritium concentration was monitored. No significant differences were noted except in two cases when …

The report covers the PC-2, C-beam chordal average density measurement made on the loss-of-fluid test (LOFT) primary coolant system hot leg during the L1-4 nonnuclear loss-of-coolant accident (LOCA) test conducted May 3, 1977. The P-2, C-beam, or LOFT advanced densitometer, used was of the pulse height analysis/energy discrimination, or nuclear hardened type to be used for LOFT nuclear tests. The L1-4 test verified the applicability of pulse height analysis/energy discrimination techniques of the nuclear hardened gamma densitometer. Test results show that the reactor coolant fluid chordal average density can be calculated from gamma radiation source signal measured count rate data.

Silicon single crystals were implanted with 100 keV phosphorus ions to a dose of 2 x 10/sup 16/ ions/cm/sup 2/ at both room-temperature and 600/sup 0/C. They were isochronally annealed at temperatures ranging from 400/sup 0/C to 900/sup 0/C. Sheet resistivity measurements of the specimens were taken after each anneal, together with corresponding transmission electron micrographs.

The cyclone incinerator was operated throughout the quarter utilizing the new lid assembly. Burning rates averaged 35.1 kg/h. Early indications are that equipment life expectancies may also have lengthened. Efforts continue on selection of a system to dry sludges generated in the off-gas treatment system. A quality control program was started this quarter. The ash/cement matrix studies were completed. The 65/35 mixture proved to be the best for dry-cure pellets, and the 80/20 mixture produced the best wet-cured pellets. Experimental incinerator ash was successfully sintered; the final carbon content was less than 0.1 wt%.

Lawrence Livermore Laboratory has tested and evaluated a commercially available getter pump for use with tritium in the Tokamak Fusion Test Reactor (TFTR). The pump contains Zr(84%)--Al in cartridge form with a concentric heating unit. It performed well in all tests, except for frequent heater failures.

Siltec Corporation's contract with JPL is directed towards the design and development of equipment and processes, to demonstrate continuous growth of crystals by the Czochralski method, suitable for producing single silicon crystals for use in solar cells. Continuous growth is defined as the growth of 100 Kg of single silicon crystal, 10 cm in diameter, from one container. Siltec's approach to meeting this goal is to develop a furnace with continuous liquid replenishment of the growth crucible, accomplished by a meltdown system and a liquid transfer mechanism, with associated automatic feedback controls. The design of the furnace elements has been completed, and all parts are now in the fabrication stage. The electronic control console regulating the growth system and meltdown system, and the liquid transfer mechanism, has been assembled. An experiment was performed with a standard production furnace, to demonstrate controlled flow of molten silicon through a small I.D. tube by pressure differential. Sections of the transfer tube system were evaluated, power requirements to balance heat losses determined, axial temperature profile in the tube, and radial temperature gradients in the heat pack were measured. A mathematical model was made for the electromagnetic throttle valve to control flow of molten silicon …

Electropolishing is a rapid and effective technique for removing plutonium and other radionuclide contamination from a variety of metal surfaces. The major objective of this continuing research is to develop electropolishing into a large-scale decontamination technique that can completely and economically remove transuranic and other surface contamination from large volumes of metallic waste. These research studies have demonstrated the ability of electropolishing to reduce the radiation levels of steel tools and stainless steel vacuum system components, which were heavily contaminated with plutonium oxide. Other examples of objects that have been decontaminated within minutes using electropolishing include hot cell manipulator assemblies, analytical instrument components, laboratory transfer containers, offsite shipping containers, fission product storage capsules, laboratory animal cages, and nuclear reactor process tube components. One of the major activities of this research has been the establishment and intensive operation of a 400-gal immersion electropolishing system designed specifically to develop and demonstrate decontamination techniques for representative plutonium- and beta/gamma-contaminated components. Substantial progress has also been made in developing in situ electropolishing techniques that can be used to decontaminate metallic surfaces that cannot readily be transported to or immersed in a conventional electropolishing tank. Sectioning/pretreatment studies are underway to develop and demonstrate optimum disassembly, …

The Ferndale Earthquake of June 7, 1975, provided a unique opportunity to study the accuracy of seismic soil-structure interaction methods used in the nuclear industry because, other than this event, there have been no cases of significant earthquakes for which moderate motions of nuclear plants have been recorded. Future studies are planned which will evaluate the soil-structure interaction methodology further, using increasingly complex methods as required. The first step in this task was to perform deconvolution and soil-structure interaction analyses for the effects of the Ferndale earthquake at the Humboldt Bay Power Plant site. The deconvolution analyses of bedrock motions performed are compared as well as additional studies on analytical sensitivity.

20 square miles were mapped in the Saddle Mountains immediately north of Hanford. Twenty-six gravel pits within and adjacent to Hanford were given preliminary characterization and no tectonically induced structures were found. Approximately 1,800 wells have been identified in the Pasco Basin which penetrate basalt. In the Waste/Basalt Interaction area, progress continued in isolating those interaction products which are primary hosts for various cations and anions. Hydrologic Hole DC-5 was completed at 3,990 feet on Feb. 9. Mine modeling studies showed that at depths of 3,000 feet, the probability of joint slip above the plane of the respository is very small.

Separate abstracts were prepared for each of the three included sections. (MOW)
