Simulation of Alpha-Channeling in Mirror Machines

Description: Applying α-channeling techniques to mirror machines can significantly increase their effective reactivity, thus making open configurations more advantageous for practical fusion. A large fraction of α particle energy can be extracted using rf waves. Effects employed to cool α particles can also in principle be used to heat the fusion ions; the possibility to design a configuration of rf waves which could be used to perform both tasks is demonstrated.

Reduction of U(VI) Complexes by Anthraquinone Disulfonate: Experiment and Molecular Modeling

Description: Past studies demonstrate that complexation will limit abiotic and biotic U(VI) reduction rates and the overall extent of reduction. However, the underlying basis for this behavior is not understood and presently unpredictable across species and ligand structure. The central tenets of these investigations are: (1) reduction of U(VI) follows the electron-transfer (ET) mechanism developed by Marcus; (2) the ET rate is the rate-limiting step in U(VI) reduction and is the step that is most affected … more

Surficial bioturbation and rapid benthic remineralization in the Cape Hatteras shelf/slope region. Final report

Description: This is a final report for the DOE of grant DE-FG02-92ER61464 ''Surficial bioturbation and rapid benthic remineralization in the Cape Hatteras shelf slope region''. Over the past 6 years we have participated in a multidisciplinary field study called the Ocean margins Program (OMP) to examine the importance of continental margins in the global carbon cycle. Specifically, we have focused on the southern portion of the Mid-Atlantic Bight between Cape Hatteras and Chesapeake Bay where a large flux … more

Radioactivity in gaseous waste discharged from the separations facilities during 1974

Description: During 1974, approximately 1.31 x 10/sup 13/ liters of gaseous effluents were monitored for radioactivity by the stack sampling program. A summary of the measured radioactivity was as follows: alpha (assumed source--Pu)--1.62 x 10/sup -3/ Ci and beta--0.201 Ci.

Potential benefits of R and D directed toward increasing the cost-effectiveness of energy use

Description: The need for energy research programs directed toward increasing the cost-effectiveness of energy use is discussed. Benefits reaped by society as a consequence of successful completion of a research activity are economic, environmental, health and safety, security, and long term; emphasis is placed on the economic benefits from research projects on the demand side (i.e., energy end-use sectors). Each end-use sector was examined and data on the amount of energy consumed and the estimated cost of… more

Opacity measurements: extending the range and filling in the gaps

Description: A series of experiments to explore Ge opacity at temperatures where the M-shell is almost filled will be discussed. Data are obtained at lower temperatures than previously explored and allow us to investigate the role of atomic structure calculations and their impact on opacity scalings. The experiment uses the Nova laser to irradiate a gold hohlraum within which a CH-tamped Ge sample is radiatively heated. A Nd backlight probes the sample 2 ns later to produce Ge spectral absorption features i… more

A simplified theoretical method of determining the characteristics of a lifting rotor in forward flight

Description: Theoretical derived expressions for the flapping, the thrust, the torque, and the profile drag-lift ratio of nonfeathering rotor with hinged, rectangular, linearly twisted blades are given as simple functions of the inflow velocity and the blade pitch. Representative values of the coefficients of each of the terms in these expressions are tabulated for a series of specified values of the tip-speed ratio. Analysis indicates that the tabulated values can be used to calculate, with reasonable accu… more

Hydrogen Separation Membranes Annual Report for FY 2008.

Description: The objective of this work is to develop dense ceramic membranes for separating hydrogen from other gaseous components in a nongalvanic mode, i.e., without using an external power supply or electrical circuitry. The goal of this project is to develop dense hydrogen transport membranes (HTMs) that nongalvanically (i.e., without electrodes or external power supply) separate hydrogen from gas mixtures at commercially significant fluxes under industrially relevant operating conditions. HTMs will be… more
