Examination of T-111 clad uranium nitride fuel pins irradiated up to 13,000 hours at a clad temperature of 990/sup 0/C

Description: The examination of 27 fuel pins irradiated in the Plum Brook reactor facility is described. Curtailment of NASA sponsored nuclear programs prevented a complete examination of all pins. Nevertheless, results include fuel pin integrity, clad ductility, clad strain, fission gas release, fuel burnup, fuel swelling, neutron fluence, metallography, and instrumentation reliability. Twenty-two fuel pins were tested for fission gas leaks; 13 pins leaked with two having visible cracks. Fuel swelling appe… more

Integrated dry NO sub x /SO sub 2 emissions control system

Description: This project's goal is to demonstrate the removal up to 70% of the NO{sub x} and 70% of the SO{sub 2} emissions from coal fired utility boilers. It will establish an alternative emissions control technology integrating a combination of several processes, while minimizing capital expenditures and limiting waste production to dry solids that are handled with convention ash removal equipment. These processes include low-NO{sub x} burners and urea injection for NO{sub x} control, sodium- or calcium… more

Characterization of cell suspensions from solid tumors

Description: The desirable features of cells in suspension will necessarily be dependent upon the use for which the cells were prepared. Adequate cell yield or recovery is defined by the measurement to be performed. Retention of cellular morphology is important for microscopic identification of cell types in a heterogenous cell suspension, and may be used to determine whether the cells in suspension are representative of those in the tumor in situ. Different dispersal protocols may yield cells with differen… more

Actinide removal from aqueous solution with activated magnetite

Description: An actinide aqueous waste treatment process using activated magnetite has been developed at Rocky Flats. The use and effectiveness of various magnetites in lowering actinide concentrations in aqueous solution are described. Experiments indicate that magnetite particle size and pretreatment (activation of the magnetite surface with hydroxyl ions greatly influence the effective use of magnetite as an actinide adsorbent. With respect to actinide removal, Ba(OH)/sub 2/-activated magnetite was more … more

The effects of tributyl phosphate on a polymeric ultrafilter

Description: The purpose of this project was to determine the effects that tributyl phosphate (TBP) would have on a polysulfone crossflow ultrafilter. Aqueous simulant solutions containing TBP (100 or 1000 mg/L) and Fe(III), Si(IV), Al(III), and NaNO{sub 3} were examined. Results obtained from simulant solutions containing 100 mg/L TBP were virtually identical to those obtained in the absence of TBP. However, a solution containing higher concentrations of TBP (1000 mg/L) very rapidly reduced the permeate fl… more

Release of ammonia from HAN-type PHA

Description: A preliminary design basis for ammonia scrubbers in the DWPF has been issued. This design basis is based on a theoretical model of ammonia evolution from the SRAT, SME and RCT. It is desirable to acquire actual process data on ammonia evolution prior to performing detailed design of scrubbers for DWPF. The evolution of ammonia from the SRAT and SME in the Integrated DWPF Melter System (IDMS) was investigated during the HM4 run. In this run, Precipitate Hydrolysis Aqueous (PHA), which was made i… more

LIMB Demonstration Project Extension and Coolside Demonstration

Description: This report presents results from the limestone Injection Multistage Burner (LIMB) Demonstration Project Extension. LIMB is a furnace sorbent injection technology designed for the reduction of sulfur dioxide (SO[sub 2]) and nitrogen oxides (NO[sub x]) emissions from coal-fired utility boilers. The testing was conducted on the 105 Mwe, coal-fired, Unit 4 boiler at Ohio Edison's Edgewater Station in Lorain, Ohio. In addition to the LIMB Extension activities, the overall project included demonstra… more

Low-density, salt-loaded foams. [RbF]

Description: An experiment was conducted at LLL that required low-density, fine-celled foams uniformly loaded with rubidium. Foams meeting these requirements were produced by impregnating foams made from polyacrylonitrile with rubidium fluoride. Foams with densities from 0.025 to 0.4 g/cm/sup 3/ were prepared and loaded with 0.002 to 0.20 g/cm/sup 3/ of rubidium fluoride.

Quality engineering and control semiannual progress report, November--December 1977 and January--April 1978

Description: Determination of ppM concentrations of dibutyl phosphate in aqueous solutions of nitric acid or sodium carbonate is possible after an extraction step with carbon tetrachloride. Ester cleavage of the fatty triglyceride constituents is the principal radiolytic reaction in irradiation of a dolphin-head oil base precision watch oil. Use of a special container and a vacuum-brazing furnace permits the high-temperature dynamic determination of volatile surface contamination from samples of large geome… more

Overconcentration in initial operation of uranium evaporator, 321 Building

Description: In the initial uranium solution testing of the Purex prototype facility uranium evaporator, failure of the concentrator feed pump, along with other contributing circumstances discussed later, resulted in an overconcentration of the uranyl nitrate solution to the point of incipient denitration. The overconcentration was accompanied by the evolution of brown nitrogen dioxide fumes from the concentrator. Examination of the evaporator contents after the incident has led to the conclusion that a rap… more

Validation of the Monte Carlo criticality program KENO IV and the Hansen-Roach sixteen-energy-group-cross sections for high-assay uranium systems. [KENO IV criticality code]

Description: Validation of the Monte Carlo criticality code, KENO IV, and the Hansen-Roach sixteen-energy-group cross sections was accomplished by calculating the effective neutron multiplication constant, k/sub eff/, of 29 experimentally critical assemblies which had uranium enrichments of 92.6% or higher in the uranium-235 isotope. The experiments were chosen so that a large variety of geometries and of neutron energy spectra were covered. Problems, calculating the k/sub eff/ of systems with high-uranium-… more

Molecular Design Concept for X-Ray Laser Research

Description: The goal of this program is the construction of an x-ray laser in the kilovolt regime. Recent experimental results indicate that a new technique for the generation of strong amplification of x-ray wavelengths is feasible. It involves the combination of (1) a new ultrahigh brightness subpicosecond laser technology and (2) a recently discovered unique mode of strong-field interaction, particularly applicable to molecules. A concept of molecular x-ray design emerges from the considerations which m… more

Thermodynamics of the solvent swelling of coal

Description: Sorption of benzene by the pyridine-extracts of premium Argonne Illinois {number sign}6 coal was studied at several relative vapor pressures at 50{degrees}C and 70{degrees}C. The amount of benzene sorbed by the extract increases linearly or nearly linearly with benzene vapor pressure. The extrapolated lines do not pass through the origin. At low pressures, a dual-mode sorption mechanism is proposed, whereby benzene concurrently fills holes (microvoids) and dissolves into the extract. At higher … more
