Energy and protein production from pulp mill wastes. Progress report, June 15, 1977--September 15, 1977

Description: Experiments conducted during this past quarter demonstrated the decided difference both in amount and composition of the gas produced from the fermentation of ozonated versus unozonated yeast-plant SSL. Gas from ozonated SSL averaged over 80% methane content while unozonated effluent was mostly carbon dioxide. Gas production rates and retention time studies indicated that the fermentation was substrate-limited. Preliminary tests using supplemental carbon sources have verified this. The success … more

Presupernova evolution of massive stars

Description: Population I stars of 15 M/sub mass/ and 25 M/sub mass/ have been evolved from the zero-age main sequence through iron core collapse utilizing a numerical model that incorporates both implicit hydrodynamics and a detailed treatment of nuclear reactions. The stars end their presupernova evolution as red supergiants with photospheric radii of 3.9 x 10/sup 13/ cm and 6.7 x 10/sup 13/ cm, respectively, and density structures similar to those invoked to explain Type II supernova light curves on a st… more

Water testing of the inducer pump. [LMFBR]

Description: The inducer pump, designed and fabricated as a test article to evaluate the inducer/impeller pump concept for providing improved suction performance of large sodium pumps, met or exceeded all performance goals. The inducer stage in front of the centrifugal impeller dramatically reduces the size of pumps. It was demonstrated that the inducer can operate at suction specific speeds in excess of 35,000, whereas conventional centrifugal pumps have demonstrated capability to only 12,000. The inducer … more

Technical study for the chemical cleaning of Dresden-1. Volume I, Section 1 and 2

Description: A feasibility study has been completed to decontaminate the primary system of the Dresden-1 Nuclear Power Unit operated by Commonwealth Edison Company of Illinois. Available data initially were searched to determine the state of the art. Solvents based on organic acids and chelates gave unsatisfactory deontamination factors or unacceptable corrosion rates when evaluated for cleaning of specimens from the Dresden-1 primary system, under static and dynamic conditions. A new proprietary cleaning s… more

Equation of state of beryllium

Description: A new, wide-range equation of state (EOS) has been constructed for Be. The composite theoretical model incorporates ionization equilibrium and condensed-matter and multiphase physics. It also satisfies all thermodynamic equilibrium constraints. The theoretical EOS has been compared with all available high-pressure and high-temperature Be data, and satisfactory agreement is generally achieved. The most interesting feature is the theoretical prediction of melting at just below 220 GPa (2 Mb), ind… more

Energy and protein production from pulp mill wastes. Progress report, September 15, 1977--December 15, 1977

Description: Effort during the past quarter was directed at two specific objectives. First, the conversion of the protein production experiments from batch to continuous operation and, second, the identification of growth stimulants to increase methane yield. Early in the project, yeast production ranging from 0.5 to 5.0 grams of dry yeast per liter had been obtained in batch cultures. Highest yields were consistently attained on SSL (spent sulfite liquor) which had been ozonated for only 10 minutes. Contin… more

Bioethical perspective on acceptable-risk criteria for nuclear-waste management

Description: Wisely managing the profound human and environmental risks of nuclear wastes requires complex moral and ethical judgments. Whereas traditional ethics is limited to interpersonal relations, a new system of ethics--bioethics--concerns man's relation with nature. Environmentalists claim that technology has upset the balance of nature, that nature is sacred and has inviolable rights, and that man must therefore regulate his behavior to conform to earth's limited carrying capacity. They also say tha… more

Cover-gas-seal component development: dynamic inflatable-plug seal improvement

Description: This report documents the 1) radial compliance and 2) low friction coating tests conducted on the CRBRP Rotating Plug Inflatable Seals per test plan N707TR810014. Test results show that narrowing the seal blade from 0.25 to 0.12 in. will effectively reduce dynamic drag from 30 to 20 lb/ft under nominal conditions and will increase seal radial compliance from 0.12 to 0.30 in. without an unacceptable rise in dynamic drag. Tests also demonstrated that application of a teflon coating to the seal we… more

Characterization of Open-Cycle Coal-Fired MHD Generators. Quarterly Technical Summary Report No. 3, January 1--March 31, 1977. [Negative Ion Formation, Electron/Slag Interaction, and Alkali/Slag Interaction]

Description: The purpose of this contract effort is to understand how nonfuel components of coal will affect the electron and alkali seed chemistry in a high temperature coal combustion system like that envisioned for direct fired MHD generators. Three specific problems are being considered during this contract period. The first problem area is to characterize the formation of negative ions due to electron attachment processes in the combustion flow. While some stable negative ions may be formed from hydroc… more

Effect of shock wave risetime on material ejection from aluminum surfaces

Description: The effect of shock wave risetime on material ejection in aluminum has been studied for loading stresses of 21 GPa. Uniform loading was accomplished with plate impact techniques by mounting specimens on a ramp wave generator. Projectile impact on one side of the wave generator produced a wave which dispersed with propagation distance. This wave was then made incident to an aluminum specimen, so that the specimen experienced non-shock loading. It was found that mass ejection from aluminum surfac… more

Isotopic HCl transfer laser

Description: An HCl laser which uses isotopic V-V energy transfer collisions as a pumping mechanism has been demonstrated. This multiline laser, which utilized an intracavity cold gas isotope filter, increased the energy from the P/sub 1/ lines of H/sup 37/Cl while decreasng the energies of the P/sub 1/ and P/sub 2/ lines of H/sup 35/Cl. Previously unreported lines, including emission from R branch transitions, have also been observed from single-line HCl and HBr lasers.

Sampling and characterization of sodium-water reaction products

Description: The products of sodium-water reactions which had taken place in the Large Leak Test Rig at the Liquid Metal Engineering Center were sampled and characterized. The products consisted of the expected compounds in the Na-O-H system, and dissolved readily in ethanol. Removal of such products from a system by melting and draining does not appear feasible, but removal by dissolution in alcoholic solvents should be investigated further.

Evaluation of a precipitation-ion exchange process for treatment of laundry waste

Description: Bench-scale pilot plant studies were conducted to evaluate chemical coagulation and ion exchange for decontamination of 2724-W laundry wastewater. Chemical coagulation is accomplished at pH 11 to avoid complexant problems and assure good transuranic radionuclide removals. Clinoptilolite is used to remove cesium and strontium. Results of the pilot plant studies are summarized as follows: Decontamination factors of 70 (strontium) and more than 100 (cesium) were achieved by chemical coagulation an… more

Welding uranium with a multikilowatt, continuous-wave, carbon dioxide laser welder

Description: A 15-kilowatt, continuous-wave carbon dioxide laser was contracted to make partial-penetration welds in 6.35-and 12.7-mm-thick wrought depleted uranium plates. Welding power and speed ranged from 2.3 to 12.9 kilowatts and from 21 to 127 millimeters per second, respectively. Results show that depth-to-width ratios of at least unity are feasible. The overall characteristics of the process indicate it can produce welds resembling those made by the electron-beam welding process.

Raman sidescatter instability in a nonuniform plasma

Description: In the various laser-fusion concepts, an intense electromagnetic wave (the laser) must propagate through an underdense plasma region where it could decay, via the stimulated Raman instability, into a Langmuir plasma wave and a scattered electromagnetic wave. Results are obtained by evaluating the ''Green's function'' response in time and space for the scattered electromagnetic waves assuming they are initiated by a ''delta-function'' source. We consider the case where the temporal growth domina… more
