Summary status of K Basins sludge characterization

Description: A number of activities are underway as part of the Spent Nuclear Fuels Project (SNFP) related to the processing and disposing of sludge in the 105-K Basins (K Basins). Efforts to rigorously define data requirements for these activities are being made using the Data Quality Objectives (DQO) process. Summaries of current sludge characterization data are required to both help support this DQO process and to allow continued progress with on-going engineering activities (e.g., evaluations of disposa… more

D0 Silicon Upgrade: Pipe Sizing for Solenoid / VLPC Cryogenic Systems

Description: The addition of a solenoid magnet and VLPC detectors are two of a number of upgrades which will occur at the D-Zero detector in the near future. Both of these upgrades will require cryogenic services for their operation. The purpose of this engineering note is to document the pipe/tube size choices made for these cryogenic services. This was done by calculating the required flow rates to cool down the magnet and VLPC's over a reasonable length of time and to determine the required piping sizes … more

D0 Silicon Upgrade: Control Dewar Steady State Thermodynamic Operating Goals

Description: This engineering note documents the thermodynamic operating parameter goals for the steady state operation of the control dewar/solenoid system. Specifically, how the control dewar pressure control valve, PV-3062-H and the magnet flow control valve EVMF are operated to give the lowest possible temperature fluid at the solenoid magnet. The goals are: (1) For PV-3062-H - The process variable is the helium reservoir pressure, minimize the reservoir pressure, provide only enough pressure plus a lit… more

Heat transfer studies. Quarterly report

Description: Nitrogen gas has been used in experimental studies related to understanding issues in the extension of multi-phase models to sub-residual saturation conditions during drying. Two different flow rates of 1 SLPM and 0.5 SLPM with a room temperature boundary condition on the aluminum column have been examined. Information about variations of humidity and temperatures is given. It is shown that the situation that exists in the experiments is somewhat different than that found in typical assumptions… more

Synthesis and Evaluation of Single Layer, Bilayer, and Multilayer Thermoelectric Thin Films

Description: The relative efficiency of a thermoelectric material is measured in terms of a dimensionless figure of merit, ZT. Though all known thermoelectric materials are believed to have ZT{le}1, recent theoretical results predict that thermoelectric devices fabricated as two-dimensional quantum wells (2D QWs) or one-dimensional (ID) quantum wires could have ZT{ge}3. Multilayers with the dimensions of 2D QWs have been synthesized by alternately sputtering thermoelectric and barrier materials onto a movin… more

Inhomogeneous primordial nucleosynthesis and new abundance constraints on {Omega}{sub b}h{sup 2}

Description: We discuss the upper limit to the baryonic contribution to the closure density. We consider effects of new observational and theoretical uncertainties in the primordial light element abundances, and the effects of fluctuation geometry on the inhomogeneous nucleosynthesis yields. We also consider implications of the possible detection of a high D/H abundance in a Lyman-{alpha} absorption cloud at high redshift and the implied chemical evolution effects of a high deuterium abundance. We show that… more

Removal of mixing pump in tank 102-AP -- pump drop onto central pit

Description: The mixing pump, if dropped in the pump pit following its removal from the tank, is incapable of compromising the tank structure either locally or in a structural displacement mode to an extent which might allow dispersion of the contents. A drop from 10 ft above the pit floor (considered the maximum credible height) of a pump which is considered perfectly rigid does not approach the required perforation velocity. The velocity required to perforate requires a drop height which is physically imp… more

Tank 241-AP-107 tank characterization plan. Revision 1

Description: Defense Nuclear Facilities Safety Board has directed the DOE to concentrate ear-term sampling and analysis activities on identification and resolution of issues (Conway 1993). The Data Quality Objective (DQO) process was chosen as a tool to be used in the resolution of safety issues. As a result, a revision in the Federal Facilities Agreement and Consent Order (Tri-Party Agreement) milestone M-44-00 has been made, which states that ``A Tank Characterization Plan (TCP) will be developed for each… more

W-007H B Plant Process Condensate Treatment Facility. Revision 3

Description: B Plant Process Condensate (BCP) liquid effluent stream is the condensed vapors originating from the operation of the B Plant low-level liquid waste concentration system. In the past, the BCP stream was discharged into the soil column under a compliance plan which expired January 1, 1987. Currently, the BCP stream is inactive, awaiting restart of the E-23-3 Concentrator. B Plant Steam Condensate (BCS) liquid effluent stream is the spent steam condensate used to supply heat to the E-23-3 Concent… more

Hong Kong's Transition to Chinese Rule: Issues, U.S. Interests, U.S. Options

Description: Participants at a CRS seminar on Hong Kong's transition to Chinese rule generally agreed that there are now-- and are likely to be more--difficulties for U.S. interests as a result of PRC pressures on Hong Kong's political autonomy, rule of law and individual rights. PRC pressures and resistance in Hong Kong could also have negative effects on U.S. interests in Hong Kong's economic progress, although Hong Kong seems poised to continue to advance economically along with the rest of coastal China. more

U.S. Trade: Proposals to Reorganize the Trade Policy Structure

Description: Several bills have been introduced in the 104th Congress to reorganize the trade policymaking structure of the executive branch. More bills are likely to be introduced. These proposals are a direct result of efforts within the Congress to dismantle the Department of Commerce. Concurrent Budget Resolution for FY1996 (Con.Res. 67), which was passed on June 29, 1995, expresses the sense of the Congress that the Commerce Department should be eliminated.
