Programmable controllers replace relays in MFTF-B personnel-safety interlocks (open access)

Programmable controllers replace relays in MFTF-B personnel-safety interlocks

This paper describes a new approach for implementing personnel safety interlocks logic using industrial-type programmable controllers. The logic for all personnel safety interlocks except those totally internal to a subsystem is implemented in two non-redundant controllers. A high degree of fail-safe reliability is achieved by augmenting the protective features intrinsic to each controller with those provided by a small amount of external support hardware. The controllers are interfaced to the host computer system via fiber optic data links to enable display of interlock and overall system status on the control room graphic displays. When fully implemented, the controllers will perform the equivalent of over 2000 discreet relay functions.

Darrieus wind-turbine and pump performance for low-lift irrigation pumping. Final report (open access)

Darrieus wind-turbine and pump performance for low-lift irrigation pumping. Final report

In the Great Plains about 15 percent of the irrigation water pumped on farms comes from surface water sources; for the United States as a whole, the figure is about 22 percent. Because of forecast fuel shortages, there is a need to develop alternative energy sources such as wind power for surface water pumping. Specific objectives of this investigation were to: design and assemble a prototype wind-powered pumping system for low-lift (i.e., < 15 m head) irrigation pumping; determine performance of the prototype system; design and test an irrigation system using the wind-powered prototype in a farm application; and determine the size combinations of wind turbines, tailwater pits, and temporary storage reservoirs needed for successful farm application of wind-powered tailwater pumping systems in western Kansas. The power source selected was a two-bladed, 6-m-diameter, 9-m-tall Darrieus vertical-axis wind turbine with 0.10 solidity and 36.1 M/sup 2/ swept area.

Evaluation of the conservation potential of a refit energy management system (using a power line subcarrier) in a large, high-rise apartment complex. Phase II (open access)

Evaluation of the conservation potential of a refit energy management system (using a power line subcarrier) in a large, high-rise apartment complex. Phase II

An energy conservation study of the application of an energy management system (EMS) utilizing power line subcarrier communication equipment was made in a large apartment building in New York, New York. The building utilized individual cooling and resistance heating units in each apartment. The EMS turned the individual units on and off (with override by tenants) on a schedule determined by the building operator. Summer savings were found to be 11%; winter savings were 20%. Annual savings were projected to be 19%. The study demonstrated the conservation value of power line subcarrier technology as an alternative to submetering. It also developed and evaluated control strategies for the system and served as a field test to accelerate commercialization of the technology.

Evaluation of Flat-Plate Photovoltaic Thermal Hybrid Systems for Solar Energy Utilization. (open access)

Evaluation of Flat-Plate Photovoltaic Thermal Hybrid Systems for Solar Energy Utilization.

The technical and economic attractiveness of combined photovoltaic/thermal (PV/T) solar energy collectors was evaluated. The study was limited to flat-plate collectors since concentrating photovoltaic collectors require active cooling and thus are inherently PV/T collectors, the only decision being whether to use the thermal energy or to dump it. it was also specified at the outset that reduction in required roof area was not to be used as an argument for combining the collection of thermal and electrical energy into one module. Three tests of economic viability were identified, all of which PV/T must pass if it is to be considered a promising alternative: PV/T must prove to be competitive with photovoltaic-only, thermal-only, and side-by-side photovoltaic-plus-thermal collectors and systems. These three tests were applied to systems using low-temperature (unglazed) collectors and to systems using medium-temperature (glazed) collectors in Los Angeles, New York, and Tampa. For photovoltaics, the 1986 DOE cost goals were assumed to have been realized, and for thermal energy collection two technologies were considered: a current technology based on metal and glass, and a future technology based on thin-film plastics. The study showed that for medium-temperature applications PV/T is not an attractive option in any of the locations studied. …

Heavy oil reservoirs recoverable by thermal technology. Annual report (open access)

Heavy oil reservoirs recoverable by thermal technology. Annual report

The purpose of this study was to compile data on reservoirs that contain heavy oil in the 8 to 25/sup 0/ API gravity range, contain at least ten million barrels of oil currently in place, and are non-carbonate in lithology. The reservoirs within these constraints were then analyzed in light of applicable recovery technology, either steam-drive or in situ combustion, and then ranked hierarchically as candidate reservoirs. The study is presented in three volumes. Volume I presents the project background and approach, the screening analysis, ranking criteria, and listing of candidate reservoirs. The economic and environmental aspects of heavy oil recovery are included in appendices to this volume. This study provides an extensive basis for heavy oil development, but should be extended to include carbonate reservoirs and tar sands. It is imperative to look at heavy oil reservoirs and projects on an individual basis; it was discovered that operators, and industrial and government analysts will lump heavy oil reservoirs as poor producers, however, it was found that upon detailed analysis, a large number, so categorized, were producing very well. A study also should be conducted on abandoned reservoirs. To utilize heavy oil, refiners will have to add various unit operations …

Test and evaluation of hot-gas cleanup devices, Phase I and II (Task 1). Technical progress report, September 1, 1981 - November 30, 1981

This report presents the status of the work performed on a program for test and evaluation of gas cleanup devices for PFBC combined cycle systems. The work was performed during the period September 1, 1981 through November 30, 1981. This is the second quarterly report since the start of the program. Work has continued to restore the pressurized fluidized bed (PFB) technology plant at Wood-Ridge, N.J. to an operational status. Preliminary designs to incorporate each of three advanced gas cleanup devices following a first stage low pressure drop inertial type separator were previously completed. The advanced devices provided by suppliers under a separate DOE contract include a ceramic bag filter, an electrostatic precipitator and an electrostatically enhanced inertial separator. The final design activity necessary to modify the facility for the test of the ceramic bag filter has been completed. Testing of each hot gas cleanup device concurrently with a DOE supplied advanced concept particle sampling system and an alkali metal content measurement system is planned to start in April 1982.

Load-deflection characteristics of small-bore insulated-pipe clamps (open access)

Load-deflection characteristics of small-bore insulated-pipe clamps

The special insulated clamps used on both FFTF and CRBR piping utilize a Belleville spring arrangement to compensate for pipe thermal expansion. Analysis indicates that this produces a non-linear, directionally sensitive clamp spring rate. Since these spring rates influence the seismic response of a supported piping system, it was deemed necessary to evaluate them further by test. This has been accomplished for the FFTF clamps. A more standard insulated pipe clamp, which does not incorporate Belleville springs to accommodate thermal expansion, was also tested. This type clamp is simple in design, and economically attractive. It may have wide application prospects for use in LMFBR small bore auxiliary piping operating at temperatures below 427/sup 0/C. Load deflection tests were conducted on 2.54 CM and 7.62 CM diameter samples of these commercial clamps.

Biaxial model for bounding creep ratchetting in shells (open access)

Biaxial model for bounding creep ratchetting in shells

The concept of elastic core stress is used to derive bounds for the maximum inelastic strains in shells of revolution subjected to pressure and cyclic thermal loads in the creep regime. Solutions are obtained for primary membrane stresses of arbitrary biaxiality and thermal bending of arbitrary biaxiality. The stress regimes where previously derived uniaxial solutions can be conservatively used are defined. The new biaxial solutions provide more efficient bounds than the uniaxial solutions for the maximum strains in pressurized spheres and cylinders.
