Evaluation of coagulant aids at high pH (open access)

Evaluation of coagulant aids at high pH

A series of tests was run on influent to the waste treatment facility, using various polyelectrolytes and organic polymeric coagulant aids. The influent wastewater originates in chemical process areas, janitorial sinks, process-area locker room showers, floor drains, and from the laundry. Previous tests on this waste had shown that Fe{sup +3} and Ca{sup +2} at pH 11.3 gave improved product quality. However, a suitable coagulant aid for use at high pH`s was needed to obtain a rapid settling rate in the flocculation/sedimentation process. Results of the tests showed that Nalco-C627 gave a good decontamination factor while yielding rapid settling rates. Betz-1175 gave the best decontamination factors; however, its settling rate needs to be improved. Test results revealed decontamination was greater at pH 11.3 than at pH 10.1. It is recommended at this time, that Nalco-C627 be used with the Fe{sup +3}, Ca{sup +2} high pH system, and that further tests be performed on the Betz-1175.

Marshall Islands radiological followup (open access)

Marshall Islands radiological followup

In August, 1968, President Johnson announced that the people of Bikini Atoll would be able to return to their homeland. Thereafter, similar approval was given for the return of the peoples of Enewetak. These two regions, which comprised the Pacific Nuclear Testing Areas from 1946 to 1958, will probably be repopulated by the original inhabitants and their families within the next year. As part of its continuing responsibility to insure the public health and safety in connection with the nuclear programs under its sponsorship, ERDA (formerly AEC) has contracted Brookhaven National Laboratory to establish radiological safety and environmental monitoring programs for the returning Bikini and Enewetak peoples. These programs are described in the following paper. They are designed to define the external radiation environment, assess radiation doses from internal emitters in the human food chain, make long range predictions of total doses and dose commitments to individuals and to each population group, and to suggest actions which will minimize doses via the more significant pathways.

Clam survival in chlorinated water (open access)

Clam survival in chlorinated water

Applications of 10 to 40 ppM chlorine were ineffective in control of Asiatic clams that had colonized the suction well of a cooling water pump for one of the Savannah River production reactors. Accumulated mud on the floors and walls of the basin protected large numbers of clams from lethal chlorine exposures. After clams were removed from chlorine exposures of 9, 17, 25, and 54 hours, respective survivals after seven days in a recovery chamber were 97 percent, 84 percent, 47 percent, and 10 percent. Of the clams that were protected by mud during the entire test (54 hours), 65 percent were alive after seven days in the recovery chamber. (auth)

Fluorescence line-narrowing studies of Nd:glass laser materials (open access)

Fluorescence line-narrowing studies of Nd:glass laser materials

The increasing importance of Nd glass lasers in laser fusion technology has emphasized the inadequacy in the understanding of the optical properties of rare earth ions in glasses. Indeed, it has been difficult to generate models for the performance of these devices, and the selection of host glasses could be done by little more than a trial-and-error approach. The technique of laser-induced fluorescence line-narrowing developed within the last few years provides a new and powerful tool for the study of these systems. In this technique, a laser excites within the inhomogeneously broadened absorption bands a selected subgroup of the ions in the system, namely those whose absorption energy is resonant with the laser. If the excitation does not migrate among the entire collection of ions prior to fluorescence, the fluorescence that is observed is only from the group that was excited and is narrowed. This permits the selective study of classes of ion sites within the ensemble. The concept is indicated schematically. By the use of a tunable laser, such as a dye laser, it is possible to vary the class of sites, defined by energy, that is excited and thereby study the important spectroscopic properties and their variations, unclouded …

Effect of temperature on the fatigue-crack propagation behavior of A-286 steel (open access)

Effect of temperature on the fatigue-crack propagation behavior of A-286 steel

The techniques of linear-elastic fracture mechanics were used to characterize the effect of temperature upon the fatigue-crack growth behavior of A-286 steel in an air environment over the temperature range of 75--1000$sup 0$F. In general, the fatigue-crack growth rate increased with increasing temperature. Two material forms were tested: 0.5 inch-thick strip material and 1.5 inch- diameter bar. Two different crack orientations were tested in each product form. In general, no significant differences in crack growth behavior were noted between product forms nor between the different crack orientations. (auth)

Spectra of $gamma$-rays from capture of 2 eV to 9 x 10$sup 4$ eV neutrons by $sup 181$Ta (open access)

Spectra of $gamma$-rays from capture of 2 eV to 9 x 10$sup 4$ eV neutrons by $sup 181$Ta

Using new experimental techniques, the spectra of $gamma$-rays from the capture of neutrons by $sup 181$Ta were measured at the Livermore 100-MeV linac for neutrons from 2 eV to 9 x 10$sup 4$ eV with a (Ge(Li)-NaI) three-crystal spectrometer. Individual primary $gamma$-ray lines were resolved to 1778-keV excitation in $sup 182$Ta. Neutron resonances were resolved to 200-eV neutron energy. Data analysis techniques and codes were developed to extract positions and intensities of resolved transitions from the large data matrices accumulated in this experiment. Techniques were developed to unfold the unresolved $gamma$- ray spectra using the simple response of the three-crystal spectrometer. The resolved transition data were used to place 110 states with spin and parity assignments in the $sup 182$Ta level diagram below 1780-keV excitation. A set of 1240 E1 transition strengths were analyzed to extract 1.38 +- 0.11 degrees of freedom for the most likely chisquared fit to the distribution of widths. The E1 strength function was extracted for E/sub gamma/ = 4 to 6 MeV and compared with previous results. The $gamma$-ray spectra for E/sub gamma/ = 1.5 to 6.1 MeV were unfolded for neutron energy groups between 20 and 9 x 10$sup 4$ eV. Below 5-MeV $gamma$-ray …

Liquid Metal Engineering Center (LMEC) annual technical progress report, January-December 1975

During operation of the prototype FFTF sodium pump, it is necessary to know the position of the pump shaft relative to the sodium-lubricated hydrostatic bearing journals. Performance of the Kaman proximity measurement system was known to be affected by the type of media between the gap to be measured. Since Kaman Sciences Corp. did not have liquid sodium testing capabilities, LMEC was requested to evaluate a spare prototype system. Determination of the sodium performance characteristics of the Kaman proximity systems was a necessary requisite for use of four prototype systems in the FFTF prototype pump test program.

Similarity solutions for convection of groundwater adjacent to horizontal impermeable surfaces with axisymmetric temperature distribution. Technical report No. 14 (open access)

Similarity solutions for convection of groundwater adjacent to horizontal impermeable surfaces with axisymmetric temperature distribution. Technical report No. 14

The axisymmetric buoyancy-induced groundwater flow adjacent to horizontal impermeable surfaces with wall temperature being a power function of radius is discussed in this paper. With the boundary layer simplifications, the governing non-linear partial differential equations can be transformed into a coupled pair of non-linear ordinary differential equations with two-point boundary conditions that can be integrated numerically by established techniques. Simple algebraic expressions for boundary layer thickness and heat transfer rate are obtained. Applications to free convective flow in a liquid-dominated geothermal system at high Rayleigh number are discussed.

Feasibility study of networks. Progress report, July 15, 1975--July 14, 1976

The Laboratory for Nuclear Science has continued its study into the feasibility of networks, changing the focus of the investigation from the possible ways of collaborating with the MIT Information Processing Center in implementing a connection to the ARPA net to a wider consideration of the implications of computer resource sharing via networks. This report describes experiments performed on the ARPA net in collaboration with the Lawrence Berkeley Laboratory and experiments in more conventional forms of remote job entry to that site and others in ERDA. It discusses the use of the Multics mail as set up for ERDA, comparing it to other mail systems. Plans for future experiments in the ARPA net and for investigation of networks other than the ARPA net are proposed. The conclusion was reached that resource sharing via networks is both feasible and desirable provided certain interface problems are solved. Recommendations are made for more investigation into the human factors involved in network use, methods of providing consulting help to users, and determination of the most cost effective use of remote resource sharing. For the Laboratory for Nuclear Science, it is concluded that access to other ERDA computers via networks will meet some of our …

Lithium--water--air battery project: progress during the month of April 1976 (open access)

Lithium--water--air battery project: progress during the month of April 1976

The kinetics of the Li electrode in LiOH(aq) was investigated. Electrode polarization was measured by voltammetric techniques. Graphs show the following results: anodic limiting current density increases with flow rate; limiting current density depends on flow rate and bulk electrolyte concentration; and electrode resistance is weakly dependent on flow rate. An intuitive model of mass transport-limited dissolution appears to be substantiated. The following tentative conclusions were reached: an upper limit to the rate of discharge of a lithium--water battery anode will be set by the mass transfer limitations of the flow system, and not by the kinetics of the charge transport within any microscopic surface films on the anode; the resistance of the anode surface film in the linear polarization region is quite low and essentially independent of flow rate; the plane parallel electrode geometry results in as low an electrode resistance as any so far investigated and should be considered for automotive battery design. 3 figures.

Energy transfer mechanisms in photobiological reactions. Progress report, 1 August 1975--30 April 1976

As in our earlier work on the sensitized photooxidation of substituted phenylalanines, ring substituents were found to have a marked effect on the photooxidation of uracil. This compound was selected as a typical pyrimidine for detailed studies of the mechanism of photooxidation of molecules of biological importance. The photooxidation of a series of 5-substituted uracils as sensitized by eosin Y, ruthenium bipyridyl, 3-methyl-lumiflavin and methylene blue was studied using oxygen electrode and flash photolysis techniques. Different substituents had very different effects on the rates of photooxidation with a given dye, and some substituents could shift the mechanism from a singlet oxygen pathway to an electron abstraction pathway (or vice versa). A study of the effects of porphyrin structure in relation to photosensitizing characteristics was completed. An examination of the localized selective photooxidation of amino acids in the vicinity of the heme binding site of horseradish peroxidase was made using specifically-bound protoporphyrin IX and other porphyrins as sensitizers. Preliminary studies were carried out on the use of sensitized photooxidation as a tool to study the contribution of histidine-containing crosslinks to the mechanical-thermal properties of mammalian tendon as well as the role of membrane properties in determining the rate and direction of …

Flowsheet development for HTGR fuel reprocessing

Development studies to date indicate that the HTGR fuel blocks can be effectively crushed with two stages of eccentric jaw crushing, followed by a double-roll crusher, a screener and an eccentrically mounted single-roll crusher for oversize particles. Burner development results indicate successful long-term operation of both the primary and secondary fluidized-bed combustion systems can be performed with the equipment developed in this program. Aqueous separation development activities have centered on adapting known Acid-Thorex processing technology to the HTGR reprocessing task. Significant progress has been made on dissolution of burner ash, solvent extraction feed preparation, slurry transfer, solids drying and solvent extraction equipment and flowsheet requirements.
