Development of low-level liquid-waste-treatment systems, October 1981-March 1982 (open access)

Development of low-level liquid-waste-treatment systems, October 1981-March 1982

A plant design for a reverse osmosis (RO) membrane unit was completed. The design includes a conceptual diagram, specifications for a RO unit producing 40 gal/min of permeated product, a list of radioisotopes tested on RO units and the rejections achieved, a discussion of the principle of RO, a discussion of the upper limits of cation and anion concentrations (there are no lower limits), a discussion of membrane configurations and porosities, a discussion of factors affecting membranes, a section on calculating the membrane area needed for a particular application, and capital and operating cost calculations. The three factors found to affect the adsorption of cobalt on ion exchange resins were investigated in an interaction effects design experiment. These factors are solution pH, and sulfite and ammonium concentrations. The effects of these factors were investigated with both anionic and cationic resins. Greater than 99% of the cobalt can usually be removed from solutions at a pH between 3 and 6. A design for an ion-exchange pilot plant was completed. The design includes a schematic diagram; flow, resin, and column specifications; impurity limits; and operating and capital costs. A short theoretical discussion and process description are also included. The design retains flexibility …

Power spool test, TSH-002, SPTF No. 19 (open access)

Power spool test, TSH-002, SPTF No. 19

The data presented in this Technical Memo will pertain to the operating characteristics of Power Spool TSH-002. This spool had a large number of thermometers built into it. These thermometers monitored most of the thermal characteristics of the 5000 A American Magnetics, Inc. vapor-cooled leads used in this power spool. Operating conditions, such as peak temperatures, ramp and dc lead cooling gas flow requirements, voltage as an indicator of stable conditions (ac and dc) and general voltage characteristics (i.e., amount of ice formed outside of leads vs high-pot voltage) were measured and observed. It was found that previous operating conditions of the power leads influenced the temperature gradients of the leads in certain cases.

Spent Fuel Test-Climax: core logging for site investigation and instrumentation (open access)

Spent Fuel Test-Climax: core logging for site investigation and instrumentation

As an integral part of the Spent Fuel Test-Climax 5150 ft (1570 m) of granite core was obtained. This core was diamond drilled in various sizes, mainly 38-mm and 76-mm diameters. The core was teken with single tube core barrels and was unoriented. Techniques used to drill and log this core are discussed, as well as techniques to orient the core. Of the 5150 ft (1570 m) of core more than 3645 ft (1111 m) was retained and logged in some detail. As a result of the core logging, geologic discontinuities were identified, joint frequency and spacing characterized. Discontinuities identified included several joint sets, shear zones and faults. Correlations based on coring along were generally found to be impossible, even for the more prominent features. The only feature properly correlated from the exploratory drilling was the fault system at the end of the facility, but it was not identified from the exploratory core as a fault. Identification of discontinuities was later helped by underground mapping that identified several different joint sets with different characteristics. It was found that joint frequency varied from 0.3 to 1.1 joint per foot of core for open fractures and from 0.3 to 3.3/ft for closed …

XUV and X-ray spectra from Texas Experimental Tokamak plasmas (open access)

XUV and X-ray spectra from Texas Experimental Tokamak plasmas

The first XUV and x-ray spectra were recorded from TEXT with a grazing-incidence grating spectrograph and new crystal spectrographs. Time- and space-integrated data yielded a qualitative description of the plasma. Line radiation from O, Cr, Fe, and Ni ions was recorded and identified with the aid of ab initio atomic structure calculations. Approximate values of plasma characteristics were obtained from the spectra. A derived electron temperature of 800 eV and electron density of 2 {times} 10{sup 13} cm{sup {minus}3} are consistent with results from other diagnostics. Spectrometers which will provide time- and space-resolved data are being designed for quantitative rate and transport studies.

Finite-element stress and deflection analysis of CDF yoke and end plug (open access)

Finite-element stress and deflection analysis of CDF yoke and end plug

A large detector is being designed to study anti pp collisions at center-of-mass energies of up to 2000 GeV as part of the Fermilab Collider Detector Facility (CDF). The central detector of this facility consists of a solenoid, calorimeter yoke, and a variety of particle measurement devices. The yoke will be a large steel structure that will provide the magnetic flux return path as well as support structure for calorimetry and other instrumentation. It must resist both electromagnetic and gravitational loads while exhibiting only small elastic deformations. The instrumented endplugs of the yoke are subjected to large electromagnetic loads. Moreover, due to the presence of wire chambers within these plugs, they must also be particularly stiff. The purpose of this paper is to present the results of a finite element stress and deflection analysis of these structures under various anticipated load conditions. The PATRAN-G finite element modeling program, installed on a CDF-VAX 11/780 and operating from a Ramtek 6212 colorgraphics terminal, was used to generate the analysis models. The actual finite element analysis was performed by the ANSYS general purpose finite element program, installed on the Fermilab Cyber 175's.

Thermal-envelop stone house, solar. Final technical report (open access)

Thermal-envelop stone house, solar. Final technical report

The purpose of this project is to create a comfortable, low-cost heating system for a single-family house, without dependence on non-renewable energy sources. I have attempted to combine a simple solar air-heating collector with the thermal envelop concept (for thermal air circulation) and massive interior stone walls for heat storage. All building materials, with the exception of the solar glazing material and certain other solar components, are inexpensive and locally produced. Examples are: rough-cut hardwood lumber, sandstone (free for the gathering), galvanized roofing for absorberplate, concrete, concrete block, and cellulose insulation. The collector has operated with a relatively high degree of efficiency, though three 0.6 amp duct fans had to be installed in order to increase air circulation. The interior stonework has provided more than adequate heat storage, along with even heat radiation throughout cloudy periods. My main problem has been heat loss around the foundation.

Microalgae as a source of liquid fuels. Final technical report. [200 references] (open access)

Microalgae as a source of liquid fuels. Final technical report. [200 references]

The economics of liquid-fuels production from microalgae was evaluated. A detailed review of published economic analyses of microalgae biomass production revealed wide variations in the published costs, which ranged from several dollars per pound for existing commercial health-food production in the Far East, to less than .05/lb costs projected for microalgae biomass for fuel conversion. As little design information or specific cost data has been published, a credible cost estimate required the conceptual engineering design and cost estimating of microalgae to liquid-fuels processes. Two systems were analyzed, shallow (2 to 3'') covered ponds and deeper (1 ft) open ponds. Only the latter was selected for an in-depth analysis due to the many technical shortcomings of the former approach. Based on the cost analysis of a very simple and low cost process, the most optimistic costs extrapolated were about $60/barrel. These were based on many optimistic assumptions. Additional, more detailed, engieering and cost analyses would be useful. However, the major emphasis in future work in this area should be on demonstrating the basic premises on which this design was based: high productivity and oil content of microalgae strains that can dominate in open ponds and which can be harvested by a …

Aging effects of US space nuclear systems in orbit (open access)

Aging effects of US space nuclear systems in orbit

This report presents information and data in support of a cost-benefit analysis being performed by Fair child Industries (FI) on the feasibility of retrieving existing US space nuclear systems in earth orbit by the Space Shuttle. This report evaluates, for US space nuclear systems presently in orbit, the radioisotopic inventory and external radiation field as a function of time, the effect of aging on fuel containment materials over the projected lifetime of the system, and the possible radioactive source terms should reentry eventually occur. Although the radioisotopic inventories and radiation fields have been evaluated for all systems, Transit 4A and Transit Triad have been emphasized in the evaluation of the aging effects and reentry consequences because these spacecraft have the shortest projected orbital lifetimes (570 and 150 years, respectively). In addition to existing systems in orbit, the radioisotopic inventory, radiation field, and reentry source terms have been evaluated for a General Purpose Heat Source (GPHS) in a parking orbit due to an aborted Galileo Mission or International Solar Polar Mission (ISPM).

Modeling beam-front dynamics at low gas pressures (open access)

Modeling beam-front dynamics at low gas pressures

The dynamics of space charge neutralization at the front of an intense self-focused electron beam pulse exhibits important differences in different gas pressure regimes. At very low pressures, the beam front is in the so-called ion-focused regime (IFR) where all secondary electrons are expelled from the beam region by the radial electric field without causing significant additional ionization. We estimate the upper pressure boundary of this regime by considering the distance scale length for cascade (avalanche) ionization. Data from the FX-25 diode experiments indicate a critical transition pressure (P/sub c/) that agrees with this estimate and with its scaling among various gas types. Normal mobility-limited treatments (local conductivity models) of the secondary electrons at the beam front are not justified until the gas pressure is 10 to 50 times higher than P/sub c/, due to runaway of these secondary electrons in the strong space-charge electric field at the lower pressures. The main conclusion of this study is that a non-local phase space (Boltzmann) treatment of the secondary electrons is required to accurately describe these different beam front regimes and the transitions between them; such a code model is currently under development.
