1993 Report on Hanford Site Land Disposal Restrictions for Mixed Wastes

Description: Since the early 1940s, the contractors at the Hanford Site have been involved in the production and purification of nuclear defense materials. These production activities have resulted in the generation of large quantities of liquid and solid radioactive mixed waste (RMW). This waste is subject to regulation under authority of both the Resource Conservation and Recovery Act of 1976{sup 2}(RCRA) and Atomic Energy Act{sup 3}. This report covers mixed waste only. Hazardous waste that is not contam… more

Accelerator structure development for NLC

Description: In the program of work directed towards the development of an X-Band Next Linear Collider accelerator structure, two different test accelerator sections have been completed, and a third is being fabricated. The first is a simple 30-cell constant-impedance section in which no special attention was given to surface finish, pumping, and alignment. The second is an 86-cell section in which the cells were precision diamond-turned by Texas Instruments Inc. The structure has internal water-cooling and… more

Acceptance criteria for corroded carbon steel piping containing weld defects

Description: Acceptance criteria for corroded low temperature, low pressure carbon steel piping containing weld defects is presented along with a typical application of these criteria. They are intended to preclude gross rupture or rapidly propagating failure due to uniform wall thinning, local wall thinning, pitting corrosion and weld defects. The minimum allowable uniform wail thickness is based on the code-of-record allowable stress and fracture criteria. Weld defects are postulated as potential sites fo… more

Achieving high fusion reactivity in high poloidal beta discharges in TFTR

Description: High poloidal beta discharges have been produced in TFTR that achieved high fusion reactivities at low plasma currents. By rapidly decreasing the plasma current just prior to high-power neutral beam injection, relatively peaked current profiles were created having high l[sub i] > 2, high Troyon-normalized beta, [beta]N > 3, and high poloidal beta. [beta][sub p] [ge] 0.7 R/a. The global energy confinement time after the current ramp was comparable to supershots, and the combination of improved M… more

Adjusted Streamflow and Storage 1928-1989 : with Listings of Historical Streamflow, Summation of Storage Change and Adjusted Streamflow : Columbia River and Coastal Basins.

Description: The development of irrigation projects since the 1830's and the construction of major dams and reservoirs since the early 1900's have altered substantially the natural streamflow regimen of the Columbia River and its tributaries. As development expanded a multipurpose approach to streamflow regulation evolved to provide flood control, irrigation, hydropower generation, navigation, recreation, water quality enhancement, fish and wildlife, and instream flow maintenance.

Advanced separation technology for flue gas cleanup. Quarterly technical report No. 4

Description: The objective of this work is to develop a novel system for regenerable S0{sub 2} and NO{sub x} scrubbing of flue gas that focuses on (a) a novel method for regeneration of spent S0{sub 2} scrubbing liquor and (b) novel chemistry for reversible absorption of NO{sub x}. In addition, high efficiency hollow fiber contactors (HFC) are proposed as the devices for scrubbing the S0{sub 2} and NO{sub x} from the flue gas. The system will be designed to remove more than 95% of the SO{sub x} and more tha… more

Advanced turbine design for coal-fueled engines

Description: The investigators conclude that: (1) Turbine erosion resistance was shown to be improved by a factor of 5 by varying the turbine design. Increasing the number of stages and increasing the mean radius reduces the peak predicted erosion rates for 2-D flows on the blade airfoil from values which are 6 times those of the vane to values of erosion which are comparable to those of the vane airfoils. (2) Turbine erosion was a strong function of airfoil shape depending on particle diameter. Different a… more

Aerosol filtration with steel fiber filters

Description: We have conducted an experimental study of aerosol penetration through a new high efficiency steel fiber filter and filter media that we developed in cooperation with Pall Corporation. Our previous studies have shown that sintered steel fiber media have significant improvements in higher filter efficiency and lower pressure drop than the previous steel filter technology based on sintered powder metal media. In the present study, we have measured the penetration of dioctyl sebacate (DOS) aerosol… more

After seven years, where`s the consensus?

Description: It has been 7 years since the discovery of copper oxide superconductors, yet there is no consensus on the correct theory for this phenomenon. The theory can be divided into 3 groups: ordinary (phonons), exotic (AF spin fluctuations, nested Fermi liquid, excitons, spin bags, odd frequency pairing), and revolutionary (Luttinger liquid, spin-charge separation, gauge theories, anyons, marginal Fermi liquid). C-axis dispersion, dHvA, and magneto-oscillations are also discussed.
