Develop real-time dosimetry concepts and instrumentation for long-term missions. Technical progress, February 1980-February 1981

Description: The goal of this project is to develop a rugged portable dosimetry system, based on microdosimetry techniques, which will measure dose and evaluate dose equivalent in a mixed radiation field. Development of the desired dosimetry system can be divided into three distinct areas: development of 1) radiation detector, 2) electronic system, and 3) mathematical techniques. Work has proceeded satisfactorily in all three of these areas during the first year of this effort.

Application of microfabrication technology to thermionic energy conversion. Final report, 1 April 1979-31 March 1981

Description: The first-year effort emphasized study of the kind of microstructures that could improve the performance of thermionic converters. Two ideas considered to have a fair chance of success emerged from this study: (1) use of a very closely spaced diode to eliminate the space-charge limitation of electron flow from emitter to collector, cesium vapor being used to control the work function of the emitter; and (2) use of field emission electrons, injected into a relatively large diode gap from microca… more

Plasma sheath region near a boundary with positive ion backscattering

Description: The sheath region at a boundary perpendicular to a magnetic field has been studied by numerically solving time-independent Vlasov-Poisson equations for a DT plasma. Boundary conditions are specified for particles entering the sheath region and for particles returning from the boundary. The effect of hydrogen ion backscatter as well as electron reemission has been examined. For a space-charge limited electron reemission condition, even a small amount of ion backscatter can change the sheath para… more

Production of aluminum-silicon alloy and ferrosilicon and commercial purity aluminum by the direct reduction process. First interim technical report, Phase D, January 1-March 31, 1981

Description: Operation of the bench AF-reactor on burden with all reducing carbon exterior to the ore pellet resulted in low metal alloy product yields and prematurely terminated runs, indicating the need for intimate contact between alumina and carbon to produce oxycarbide liquid prior to reaction with solid silicon carbide. Carbon solubility tests made on 60Al-40Si alloys at 2200/sup 0/C in graphite crucibles indicated continued reaction to form SiC for one hour. Efficiency of reduction to SiC ranged from… more

Characterization of transuranium- contaminated solid wastes residues

Description: The selection of technologies for the immobilization of transuranic wastes will depend in part upon the chemical and physical nature of the wastes. Characterization of some of the more important defense transuranic wastes is necessary to develop and evaluate alternative immobilization systems that might be applied to selected defense transuranic wastes. Process sludge and incinerator ash were selected for detailed study because of their importance in the transuranic waste inventory and because … more

Acceptability of reactors in space

Description: Reactors are the key to our future expansion into space. However, there has been some confusion in the public as to whether they are a safe and acceptable technology for use in space. The answer to these questions is explored. The US position is that when reactors are the preferred technical choice, that they can be used safely. In fact, it dies not appear that reactors add measurably to the risk associated with the Space Transportation System.

Transposable elements and genetic instabilities in crop plants

Description: Transposable elements have long been associated with certain unstable loci in maize and have been intensively studied by McClintock and others. It is known that a transposable element can control the expression of the structural genes at the locus where it resides. These controlling elements in maize are now beginning to be studied at the molecular level. Using recombinant molecular probes we have been able to describe the changes induced by the controlling element Ds at the shrunken locus. Ds … more

Ventilation requirements for control of occupancy odor and tobacco smoke odor: laboratory studies. Final report

Description: Experiments on occupancy odor addressed the question of why required ventilation rate per occupant increased progressively with increases in the number of persons in a space. In order to investigate ventilation requirements under approximately ideal conditions, we constructed an aluminum-lined environmental chamber with excellent control over environmental conditions and a ventilation system that provided rapid and uniform mixing of air. Psychophysical experiments on occupancy odor explored 47 … more

Use of extractive distillation to produce concentrated nitric acid

Description: Concentrated nitric acid (> 95 wt %) is needed for the treatment of off-gases from a fuels-reprocessing plant. The production of concentrated nitric acid by means of extractive distillation in the two-pot apparatus was studied to determine the steady-state behavior of the system. Four parameters, EDP volume (V/sub EDP/) and temperature (T/sub EDP/), acid feed rate, and solvent recycle, were independently varied. The major response factors were percent recovery (CPRR) and product purity (CCP). S… more

Photothermal spectroscopy of aerosols

Description: In situ aerosol absorption spectroscopy was performed using two novel photothermal detection schemes. The first, based on a photorefractive effect and coherent detection, called phase fluctuation optical heterodyne (PFLOH) spectroscopy, could, depending on the geometry employed, yield particle specific or particle and gas absorption data. Single particles of graphite as small as 1 ..mu..m were detected in the particle specific mode. In another geometrical configuration, the total absorption (bo… more

Uncovering and Evaluation of a Twenty-Five-Year-Old Underground-Coal-Gasification Burn at a Site in Gorgas, Alabama

Description: During the late forties and into the fifties, the US Bureau of Mines (USBM) and the Alabama Power Company conducted a series of underground coal gasification burns in the Pratt and America coal beds at Gorgas, Alabama. Following the first burn, by the so called stream method, it was feasible to enter the burned out areas by deep mining and assess what had taken place during the operation of the test site. In the latter tests, however, it was not economically feasible to explore the burned out a… more

Solid circulation around a jet in a fluidized-bed gasifier. Final report

Description: The main purpose of the study was the analysis of particle circulation in the jet region of a fluidized bed gasifier. The two fundamental questions answered by this report relate to the measurement of particle velocities in the grid region and to the relevance of the jet zone to the operation of the reactor. Particle velocities were measured at corresponding points within a jet in the two-dimensional bed, using the optical fiber probe and a Laser Doppler Velocimeter (LDV). The probe measurement… more

Educating the design professional: energy-conscious design for commercial buildings

Description: The energy problem in a residence is substantially different from that in a commercial building; therefore, the approach to using renewable resources in a commercial building differs from that in a residence. For this reason, educational materials, seminars, and workshops developed to teach architects and engineers basic design principles to integrate renewable energy into commercial buildings must differ from that developed for residential building designers. The purpose of this paper is to id… more

Non-equilibrium and equilibrium sorption with a linear-sorption isotherm during mass transport through an infinite, porous medium: some analytical solutions

Description: Analytical solutions have been developed for the problem of solute transport in a steady, three dimensional field of groundwater flow with non-equilibrium mass transfer of a radioactive species between fluid and solid phases and with anisotropic hydrodynamic dispersion. Interphase mass transport is described by a linear rate expression. Solutions are presented also for the case of equilibrium distribution of solute between fluid and solid phases. Three types of release from a point source were … more
