Evaluation of ultrafiltration membranes for treating low-level radioactive contaminated liquid waste

Description: A series of experiments were performed on Waste Disposal Facility (WD) influent using Romicon hollow fiber ultrafiltration modules with molecular weight cutoffs ranging from 2000 to 80,000. The rejection of conductivity was low in most cases. The rejection of radioactivity ranged from 90 to 98%, depending on the membrane type and on the feed concentration. Typical product activity ranged from 7 to 100 dis/min/ml of alpha radiation. Experiments were also performed on alpha-contaminated laundry w… more

System for vacuum pouring of epoxy tensile and impact specimens with a study of the behavior of these specimens at 77 K and 293 K

Description: The purpose of the investigation was to establish a suitable technique for vacuum pouring of epoxy test specimens and to study the behavior of these specimens at 77 K and 293 K. A series of tensile and impact tests was conducted using specimens made from the following resins: Epon 828, Epon 871, and Epon curing agent Z. These materials are of general interest to designers of magnets for cryogenic service. Tests of the specimens were carried out at 77 K and 293 K. The 77 K data indicate that ten… more

Solar Pilot Plant, Phase I. Quarterly report No. 5, October--December 1976

Description: Collector subsystem research experiment (SRE) tests were conducted and the data evaluated. Assembly of the SRE steam generator was almost complete. Testing will start in January 1977. Two major changes in the baseline design, sensible thermal heat storage rather than phase-change storage and wet rather than dry cooling of the condenser, were being worked. Analytical and design work on the electrical generation subsystem and plant integration progressed satisfactorily.

Beneficial uses of nuclear fission wastes

Description: Sandia is investigating the use of /sup 137/Cs from radioactive waste to reduce the pathogen levels of municipal sewage sludges so that they can be used in agriculture, either as fertilizer or as feed supplement. The Sandia Irradiator for Dried Sewage Solids (SIDSS) is a pilot plant for treating 16 tons per day to a dose of 500 krad, using 1 MCi of /sup 137/Cs. A larger (25 ton/day) demonstration plant is also planned. A cost/benefit study of this application was made. Use of /sup 99/Tc for mar… more

High-temperature explosive development for geothermal well stimulation. Final report

Description: A two-component, temperature-resistant liquid explosive called HITEX has been developed which is capable of withstanding 561/sup 0/K (550/sup 0/F) for 24 hours in a geothermal environment. The explosive is intended for the stimulation of nonproducing or marginally producing geothermal (hot dry rock, vapor-dominated or hydrothermal) reservoirs by fracturing the strata in the vicinity of a borehole. The explosive is inherently safe because it is mixed below ground downhole from two nondetonable l… more

Description: A two-year researth program to design and demonstrate the technical feasibility of a high-temperature solid-electrolyte fuel cell is described in detail. A rare-earth chromite, in particular, La /sub 95/Mg /sub 05/Cr /sub 75/Al /sub 25/0/sub 3/ was identified, synthesized by RF-sputtering tested for resistivity, thermal expansion and inertness in contact with yttria-stabilized zirconia, and was found promising as a candidate interconnection material. Films of these interconnection materials hav… more

Data accumulation on the methane potential of the coal beds of Colorado. Final report

Description: A two-year project was conducted to gather data that would assist in the evaluation of the methane potential of the coal beds of Colorado. It was found that a number of closed underground coal mines in the State had reported gassy conditions or had experienced fires and explosions of varied intensity and frequency. The majority of such occurrences have been in those areas characterized by coals of relatively low (i.e., below 31%) volatile matter (VM) content. The south half of the Raton Mesa co… more

Benefits and impacts of multi-level emission standards on the fuel economy characteristics of small and large cars

Description: A brief review of the small car vs large car fuel economy and emission scenario was conducted to determine whether it is meaningful to implement multi-level emission regulations (different values for small and large cars) to encourage or forces the use of catalytic converters on smaller cars, and by so doing improve the overall fuel economy of the total fleet while at the same time reduce overall emissions. The results of this review showed that: the 1975 to 1976 federal HC standard (1.5 gr/mi)… more

Delayed fracture of silicon. Silicon sheet growth development for the Large Area Silicon Sheet Task of the Low Cost Silicon Solar Array Project. Final report

Description: Bar specimens were cut from ingots of single crystal silicon, and acid-etched prior to testing. Artificial surface flaws were introduced in specimens by indentation with a Knoop hardness tester. The specimens were loaded in four-point bending to 95% of the nominal fracture stress, while keeping the surface area, containing the flaw, wet with test liquids. No evidence of delayed fracture, and, therefore stress corrosion, of single crystal silicon was observed for liquid environments including wa… more

Compact heat exchangers for sea thermal power plants. Final technical progress report, May 1, 1977--March 31, 1978

Description: The investigative studies required to develop a low cost, high performance flat plate heat exchanger design suitable for sea thermal power plants are covered. The studies indicate that higher boiling transfer coefficients quoted in the literature can be attained in a flat plate exchanger. The study has examined the effect of various fouling rates.

Spent fuel demonstration tests: Best Effort Schedule

Description: A Best Effort Schedule has been developed for the storage and demonstration test of spent fuel in the Near-Surface Facility (NSTF). The primary goal is the earliest, safe storage of a spent fuel canister in a representative near-surface flow of Columbia Plateau basalt. Based on this goal, the Best Effort Schedule makes maximum use of existing equipment and technology. Consequently, this schedule provides little prototype development or learning in the areas of spent fuel packaging or remote han… more

Energy transfer mechanisms in photobiological reactions. Final report, 1 April 1960--31 March 1979. [Photodynamic processes in selected biomolecules]

Description: This project was concerned primarily with studies of the mechanisms of the sensitized photooxidation of selected biomolecules using a variety of phtosensitizers. Such reactions are often termed photodynamic processes. In particular we have carried out steady-state kinetic studies, flash photolysis and spectral studies, and product formation studies of the sensitized photooxidation of the five susceptible amino acids (cycteine, histidine, methonine, tryptophan, and tyrosine) and their derivative… more

Dip coating process. Silicon sheet growth development for the large-area silicon sheet task of the Low Cost Silicon Solar Array Project. Quarterly report No. 5, December 18, 1976--March 21, 1977

Description: Ceramic substrates can be coated with a thin layer of large-grain polycrystalline silicon by a dip-coating process. The silicon-on-ceramic (SOC) material appears to be quite promising as a low-cost cell material but requires somewhat special fabrication procedure since the contacts to both the n- and p-layers are now made on the front surface. Solar cells have been made on SOC material and on single-crystal control samples. Photodiodes 0.01 to 0.1 cm/sup 2/ made on substrates coated with vitreo… more

Semiautomatic MDF deburring tool. [Mild detonating fuse]

Description: A device for semiautomatically deburring the ends of lengths of MDF (mild detonating fuse) was developed by the Automation Development group at Mound Laboratory. The device performs the deburring function by cutting a 0.002 in. x 0.002 in. chamfer on the MDF with small rotating blades. This air-operated, semiautomatic device provides improvement over the manual method of removing burrs by reduction in time and operator strain. A time study is underway to determine the time saved which is expect… more
