Quadrupole mass-filter sensitivities of H/sub 2/, HD, D/sub 2/, and T/sub 2/, and the kinetics of. beta. -particle induced exchange between H/sub 2/, D/sub 2/, and T/sub 2/ at 25. 4/sup 0/C

Description: We have constructed a quadrupole-mass filter system to measure the equilibrium constants and rates of reaction of the ..beta..-particle-induced exchanges between H/sub 2/, D/sub 2/, and T/sub 2/ at cryogenic temperatures. Even with careful calibration experiments at 25.4/sup 0/C, we could not completely remove the mass discrimination inherent in our method. We estimate the accuracy of our mixture analyses to be +-2.2% in the D/sub 2/-DT-T/sub 2/ system, and +-9% in the H/sub 2/-HT-T/sub 2/ syst… more

Fundamental characterization of alternate fuel effects in continuous combustion systems

Description: The overall objective of this contract is to assist in the development of fuel-flexible combustion systems for gas turbines as well as Rankine and Stirling cycle engines. The primary emphasis of the program is on liquid hydrocarbons produced from non-petroleum resouces. Fuel-flexible combustion systems will provide for more rapid transition of these alternate fuels into important future energy utilization centers (especially utility power generation with the combined cycle gas turbine). The spe… more

Beam and plasma direct converters

Description: Two types of direct converters, one for beams and one for plasma, are under development with voltages and power densities approaching reactor-like conditions. Beam direct conversion raises the efficiency of producing neutral beams, can save millions of dollars when applied to next-generation experiments, and can improve the power balance of driven reactors. Direct conversion allows positive ion beams to be made into neutrals efficiently up to 150 keV for D/sup 0/, 225 keV for T/sup 0/ and 300 k… more

PWR Blowdown Heat Transfer Separate-Effects Program. Thermal-Hydraulic test Facility experimental data report for Test 168R

Description: Reduced instrument responses are presented for Thermal-Hydraulic Test Facility (THTF) test 168R, which is part of the ORNL Pressurized-Water Reactor (PWR) Blowdown Heat Transfer Separate-Effects Program. The objective of the program is to investigate the thermal-hydraulic phenomenon governing the energy transfer and transport processes that occur during a loss-of-coolant accident in a PWR system. Test 168R was conducted to obtain thermal-hydraulic and CHF information in the THTF bundle 1 to com… more

Cumulative fuel commitment for light water reactors: is there a uranium crunch. The fusion-fission fuel factory can help

Description: It can cautiously be stated that there is not an imminent U.S. uranium crunch, because the installed capacity of fission reactors to 1990 is less than was anticipated. We have time for careful judgment and deliberation. We probably have until at least the year 2000 before beginning the phasing-in of a new technology to augment or replace the light water reactor. Consequently the fusion-fission hybrid appears to have strong potential as a fuel factory supplying fuel to the LWR industry. The hybr… more

Thin film battery/fuel cell power generating system. Seventh quarter report, October 1977-December 1977

Description: The purpose of this research program is the demonstration of the technical feasibility of a high-temperature, solid-electrolyte fuel cell, building on the presently-existing technological base. The bulk of the work consists of identifying and selecting candidate component materials, fabricating cells and cell stacks from these materials, and testing these cells and cell stacks under conditions which might be expected in operation. The major emphasis is on the invention and fabrication of an int… more

Economic significance of Q for mirror reactors: combinations of Q and M which look promising

Description: This term Q is the ratio of the fusion powder produced to the power input. It is a driven device. Q is truly the success parameter for mirrors--widely discussed but not succinctly specified as to required value. The problem is that Q can be treated as a subjective parameter--there are many milestone Qs; for scientific demonstration, for breakeven power, etc. Yet for a successful reactor, there is only one Q and that is the Q which produces mirror fusion power at the busbar that is less than the… more

Nonfactorizability of inclusive distributions in perturbative QCD. [Leading algorithms approximation, large-angle gluon correction, transverse momentum]

Description: Inclusive distribution for lepton pair production was studied in QCD in an improved leading logarithms approximation that allows for large angle gluon correction. A formula is derived for arbitrary values of the dilepton transverse momentum. It does not factorize into the generalized Drell--Yan form. 10 references.

Additional media studies for site suitability criteria

Description: Site suitability studies have been made previously at LLL on bedded salt and shale. In the present study domed salt, basalt, and crystalline rock are compared with bedded salt and shale and with each other as possible repositories. The level of effort required to develop models for these media that are similar in quality to those available for bedded salt and shale is evaluated. The effort necessary to develop data bases on the physical and chemical properties comparable to that available for b… more

Survey of mirror machine reactors

Description: The Magnetic Mirror Fusion Program is one of the two main-line fusion efforts in the United States. Starting from the simple axisymmetric mirror concept in the 1950's, the program has successfully overcome gross flute-type instabilities (using minimum-B magnetic fields), and the most serious of the micro-instabilities which plagued it (the drift-cyclotron loss-cone mode). Dense plasmas approaching the temperature range of interest for fusion have been created (n/sub p/ = 10/sup 14//cc at 10 to … more

Development of mullite substrates and containers. Silicon sheet growth development for the large area; Silicon Sheet Task of the Low-Cost Silicon Solar Array Project. Quarterly report No. 3, April 1 1978--July 15, 1978

Description: Microstructural analysis of sessile drop experiments of silicon on mullite indicate reaction at the liquid solid interface which is especially severe after ten hours. Compositional variation including higher purity and elimination of the glass phase did not affect the reaction. The increased surface area of porous samples caused severe structural damage to these substrates. Reaction phases are found away from the interface after long exposure. Compositional variations have been found to lower t… more

Preliminary measurements of plasma density

Description: The phase velocity of a microwave signal propagating in a plasma is increased providing that its frequency is much higher than the plasma frequency. It follows that by forming a resonator around the plasma and noting the resonant frequency shift plasma frequency and thus plasma density may be measured. To check the feasibility of this type of measurement, a section of vacuum pipe in the HIF beam transport line was resonated and the frequency shift resulting when beam was turned on was noted.

Description: The overall purpose of this two-stage program is the demonstration of continuous Czochralski growth. In Stage 1, an existing Varian 2850 Czochralski furnace is to be modified for continuous growth by recharging; in Stage 2, a new puller is to be designed and shown capable of producing 100 kg of crystal from the same crucible with an after-grind yield of at least 70%. The three components required to modify the Varian furnace for batch and continuous recharging with granular silicon have been de… more

Boltzmann approach to conductivity calculations

Description: The basic set of equations is derived for the calculation of the time-dependent electrical conductivity of an initially unionized gas generated by a propagating relativistic electron beam. In contrast with previous work, which used thermal averages, conductivity is determined from the complete, nonequilibrium electron energy distribution. The evolution of the distribution function, resulting from interaction with gas molecules, ions, beam induced electric field, and beam current, is described b… more
