Analytical theory of ion-temperature-gradient instability

Description: The relationship between the threshold values of ion-temperature-gradient instabilities and the temperature parameters of plasmas is investigated analytically in slab and toroidal geometries separately. It is found that the threshold values increase rapidly when the ion temperature becomes much higher than the electron temperature. The change of the threshold vaues with respect to the ion temperature is quite similar for both geometric models. This finding is consistent with PLT observations. F… more

Fluidized bed incineration process design for transuranic waste

Description: A fluidized bed incineration facility has been installed at the Rocky Flats Plant to develop and demonstrate a process for the combustion of transuranic waste. The unit's capacity is about 82 kg/hr of combustible solid waste, which is nine times higher than the rate for the operating pilot-scale unit. The facility utilizes nonaqueous, in situ neutralization of acid gases. These gases are generated during the combustion of halogen-containing materials. The low-temperature (550 /sup 0/C) ope… more

CaO interaction in the staged combustion of coal

Description: The LIMB (limestone injection multi-stage burner) process offers special potential for reducing NO/sub x/ and SO/sub x/ by at least 50 percent in coal combustion. This is to be accomplished by adding limestone with fuel and/or air in a low NO/sub x/ burner. This program has been directed to defining the chemistry and kinetics necessary to optimize sulfur capture in LIMB combustion. More specifically, this program has attempted to clarify the role of calcium sulfide in LIMB chemistry. When limes… more

Energies of organic compounds. Technical progress report. [Ketals, orthoesters, norbonyl ketals]

Description: Two automated reaction calorimetry systems were built and tested. The first made use of a quartz thermometer probe as the temperature measuring element. The second was constructed using a thermister which was part of a Wheatstone bridge. The off-balance voltage from the bridge was measured using the 6 1/2 digit digital voltmeter, and transferred to the microprocessor. The one disadvantage of the first system is the relatively large size of the quartz sensor. The calorimeter systems were used to… more

Time-resolved soft-x-ray studies of energy transport in layered and planar laser-driven targets

Description: New low-energy x-ray diagnostic techniques are used to explore energy-transport processes in laser heated plasmas. Streak cameras are used to provide 15-psec time-resolution measurements of subkeV x-ray emission. A very thin (50 ..mu..g/cm/sup 2/) carbon substrate provides a low-energy x-ray transparent window to the transmission photocathode of this soft x-ray streak camera. Active differential vacuum pumping of the instrument is required. The use of high-sensitivity, low secondary-electron en… more

Discrete-event simulation of nuclear-waste transport in geologic sites subject to disruptive events. Final report

Description: This report outlines a methodology to study the effects of disruptive events on nuclear waste material in stable geologic sites. The methodology is based upon developing a discrete events model that can be simulated on the computer. This methodology allows a natural development of simulation models that use computer resources in an efficient manner. Accurate modeling in this area depends in large part upon accurate modeling of ion transport behavior in the storage media. Unfortunately, developm… more

Direct-interaction approximation and statistically steady states of three nonlinearly coupled modes

Description: The direct-interaction approximation is used to find statistically steady states of a system of three modes, with complex frequencies, coupled by a quadratic nonlinearity. These states are compared to the exact predictions of an ensemble of realizations with Gaussianly distributed initial conditions. The direct-interaction approximation is shown to be reasonably successful in this context.

The coupling of stimulated Raman and Brillouin scattering in a plasma

Description: The observation of an anti-Stokes satellite in the spectrum of light backscattered from a CO{sub 2} laser plasma is reported. Its origin is found to be Thomson scattering of the incident light from a counterpropagating mode-coupled plasma wave. The parent electron and ion waves in the mode-coupling process were driven by stimulated Raman and Brillouin backscattering. The parent and daughter plasma waves were detected by ruby laser Thomson scattering. A computer simulation modeling the experimen… more

Brayton-cycle heat-recovery system characterization program. Component test plan

Description: The critical components of the glass furnace subject to corrosion/erosion are: the valve gate and the valve seat bottom and sides which can also be subject to warpage causing subsequent leakage and the furnace flues (or ducting). The Brayton System will be added to the glass furnace just downstream of the reversal valve. Hence, the inlet air to the flues will no longer be at ambient temperature but at a higher level between 800 to 1000/sup 0/F. Also, the exhaust gas for the Brayton System is re… more

Continued investigations into techniques producing selective chemical reactions on surfaces and target spheres and related studies. Final report

Description: This report describes efforts leading to the development and characterization of a compact ion source and optical transfer system producing relatively high current density ion beams. The ion source and beam transfer system represent a major advance in the state of the art in that high current densities at low kinetic energies have been achieved for high molecular weight polyatomic ions. Indeed, the ion beams produced display ion abundance patterns typical of simple low energy electron impact io… more

Fireset

Description: FIRESET is a PC-based computer code which calculates current as a function of time for an RLC circuit containing up to fifteen series conductors which undergo rapid heating and subsequent explosion as a consequence of an electric current which passes through them. In its original form, the code was developed to model electrical waveforms measured when a large, typically 25.4 x 25.4 x 0.051-mm, aluminum foil was exploded using a capacitor bank with tens of kilojoules of stored energy. The code p… more

Thermal conductivity of rocksalt and other geologic materials from the site of the proposed waste isolation pilot plant

Description: The measurements first reported by Acton on the thermal conductivity of samples taken from a borehole at the site of the proposed nuclear waste isolation pilot plant (WIPP) near Carlsbad, NM, have been extended to include additional samples and higher temperature measurements. Samples for measurements were taken from several depths of three wells, including the well AEC 8 from which Acton obtained his samples. These samples ranged from relatively pure rocksalt (NaCl) with small amounts of inter… more

Initial operation and performance of the PDX neutral-beam injection system

Description: In 1981, the joint ORNL/PPPL PDX neutral beam heating project succeeded in reliably injecting 7.2 MW of D/sup 0/ into the PDX plasma, at nearly perpendicular angles, and achieved ion temperatures up to 6.5 keV. The expeditious achievement of this result was due to the thorough conditioning and qualification of the PDX neutral beam ion sources at ORNL prior to delivery coupled with several field design changes and improvements in the injection system made at PPPL as a result of neutral beam oper… more

Influence of gyroradius and dissipation on the Alfven-wave continuum

Description: It is well known that in ideal magnetohydrodynamics there is a continuous spectrum of real frequencies associated with a singularity of the shear Alfven waves on the surface k/sub parallel to/v/sub A/ = omega. It is also known that the introduction of first-order gyroradius effects eliminates the continuum. In the present work we examine the influence of the full gyroradius response and of dissipation on the continuum. In the absence of dissipation we first confirm that if only first-order gyro… more

Thermal-envelop stone house, solar. Final technical report

Description: The purpose of this project is to create a comfortable, low-cost heating system for a single-family house, without dependence on non-renewable energy sources. I have attempted to combine a simple solar air-heating collector with the thermal envelop concept (for thermal air circulation) and massive interior stone walls for heat storage. All building materials, with the exception of the solar glazing material and certain other solar components, are inexpensive and locally produced. Examples are: … more
