A Bottom-Up Engineering Estimate of the Aggregate Heating and Cooling Loads of the Entire U.S. Building Stock
A recently completed project for the U.S. Department of Energy's (DOE) Office of Building Equipment combined DOE-2 results for a large set of prototypical commercial and residential buildings with data from the Energy Information Administration (EIA) residential and commercial energy consumption surveys (RECS, CBECS) to estimate the total heating and cooling loads in U.S. buildings attributable to different shell components such as windows, roofs, walls, etc., internal processes, and space-conditioning systems. This information is useful for estimating the national conservation potentials for DOE's research and market transformation activities in building energy efficiency. The prototypical building descriptions and DOE-2 input files were developed from 1986 to 1992 to provide benchmark hourly building loads for the Gas Research Institute (GRI) and include 112 single-family, 66 multi-family, and 481 commercial building prototypes. The DOE study consisted of two distinct tasks : (1) perform DOE-2 simulations for the prototypical buildings and develop methods to extract the heating and cooling loads attributable to the different building components; and (2) estimate the number of buildings or floor area represented by each prototypical building based on EIA survey information. These building stock data were then multiplied by the simulated component loads to derive aggregated totals by region, …

Building trust and confidence in laboratory ES and H policy and practices
This report describes a successful pilot event among LANL employees that can see as a model for employee involvement and community input. The conference was designed to begin building trust and confidence in Laboratory policy and practices in the area of Environment, Safety, and Health (ES and H). It represents a concrete step toward fostering better relationships among Lab employees and creating a new, innovative approach to communication that can also be used to build trust in the larger community. Based on the proven methods of the National Issues Forums and the Jefferson Center Citizen Jury Process, this conference enabled management to learn more about the thoughts and advice of LANL employees, During the course of the day, a random sample of Lab employees representing the LANL workforce learned about issues of health, safety and the environment, and some of the options available to increase trustworthiness in these areas. These Employee Advisors then discussed the options at some length and presented recommendations to senior Lab managers in the role of Decision Makers. At the end of the day, the participants offered their reflections and discussed what they learned during the conference, and Decision Makers responded to what they heard. The …

CALIBRATION OF THE CRATED WASTE ASSAY MONITOR (CWAM) FOR DEPLOYMENT AT THE Y-12 PLAN
The Crated Waste Assay Monitor (CWAM) system was designed at Los Alamos National Laboratory to address safeguards and waste measurements issues at the Oak Ridge Y-12 Plant. CWAM utilizes the differential dieaway technique (DDT) to measure {sup 235}U-contaminated waste inside B-25 waste crates. The performance objectives for CWAM were twofold: (1) ensure large quantities of material do not leave the Y-12 Plant via waste boxes, and (2) measure fissile contamination at levels as low as the Tennessee landfill limit of 35 pCi/g. This paper begins with a history of the CWAM project describing the motivation for the redesign effort, original goals set for the project, and the design choices made to achieve these goals. The remainder of the paper presents experimental results from a matrix calibration study that included both passive and active assays on three hydrogenous matrices, two B-25 crates and one SWB, and one metallic B-25 crate. The reduction in spatial variation with multiple interrogation positions for each of the surrogate matrices is shown. Sensitivity values for these matrices are also given both in terms of {sup 235}U mass (g) and activity concentration (pCi/g).

Carbon dioxide reuse and sequestration: The state of the art today
Atmospheric concentrations of CO{sub 2} and other greenhouse gases (GHGs) are growing steadily. GHG levels seem likely to grow more quickly in the future as developed countries continue to use large amounts of energy, while developing countries become wealthy enough to afford energy-intensive automobiles, refrigerators, and other appliances (as well as live and work in larger, more comfortable structures). To keep GHGs at manageable levels, large decreases in CO{sub 2} emissions will be required. Yet analysts understand the difficulty of developing enough zero- and low-carbon-emission technologies to meet the goal of safe GHG stabilization. Carbon sequestration technologies can help bridge this gap. These technologies are only beginning to be developed, but their promise is already evident. In Europe, CO{sub 2} has been continuously and safely pumped into a below-sea limestone structure for over three years, where it remains. In New Mexico, CO{sub 2} is being used to drive out natural gas from within unminable coal seams 1,000 meters below the surface, and again, continuously injected CO{sub 2} has stayed sequestered for over three years, even though the project was designed for natural gas production, not CO{sub 2} sequestration. These and other beginnings suggest that much CO{sub 2} could be reused …

The Challenges of Developing and Integrating a Quality Management System in a Research and Development Organization
Tailoring a quality management system to the specific needs of an organization is difficult to say the least. The existence of quality system models and standards help facilitate this process immensely. However, what does an organization do when its work is so unique that quality system models and standards do not exist for it? This and other obstacles are what the Nonproliferation, Arms Control, and International Security (NAI) Directorate at Lawrence Livermore National Laboratory (LLNL) encountered during strategic initiatives to develop and integrate a new quality management system. This paper will answer this question to help similar initiatives by: Introducing NAI and its unique mission, organization, history, culture and the security environment in which it operates; Examining the obstacles to designing and integrating NAI's quality management system; Discussing the steps taken to ensure success of the strategic quality initiatives; Presenting the quality management system and plan that resulted from these efforts; Presenting the improvements in NAI and LLNL that resulted from these strategic initiatives; and Presenting lessons learned and practical recommendations.

Characteristics of Novel InGaAsN Double Heterojunction Bipolar Transistors
The authors demonstrate, for the first time, both functional Pnp AlGaAs/InGaAsN/GaAs (Pnp InGaAsN) and Npn InGaP/InGaAsN/GaAs (Npn InGaAsN) double heterojunction bipolar transistors (DHBTs) using a 1.2 eV In{sub 0.03}Ga{sub 0.97}As{sub 0.99}N{sub 0.01} as the base layer for low-power electronic applications. The Pnp InGaAsN DHBT has a peak current gain ({beta}) of 25 and a low turn-on voltage (V{sub ON}) of 0.79 V. This low V{sub ON} is {approximately} 0.25 V lower than in a comparable Pnp AlGAAs/GaAs HBT. For the Npn InGaAsN DHBT, it has a low V{sub ON} of 0.81 V, which is 0.13 V lower than in an InGaP/GaAs HBT. A peak {beta} of 7 with nearly ideal I-V characteristics has been demonstrated. Since GaAs is used as the collector of both Npn and Pnp InGaAsN DHBTs, the emitter-collector breakdown voltage (BV{sub CEO}) are 10 and 12 V, respectively, consistent with the BV{sub CEO} of Npn InGaP/GaAs and Pnp AlGaAs/GaAs HBTs of comparable collector thickness and doping level. All these results demonstrate the potential of InGaAsN DHBTs as an alternative for application in low-power electronics.

CHARACTERIZATION OF DAMPING IN BOLTED LAP JOINTS
The dynamic response of a jointed beam was measured in laboratory experiments. The data were analyzed and the system was mathematically modeled to establish plausible representations of joint damping behavior. Damping is examined in an approximate, local linear framework using log decrement and half power bandwidth approaches. in addition, damping is modeled in a nonlinear framework using a hybrid surface irregularities model that employs a bristles-construct. Experimental and analytical results are presented.

Closure Plan for Corrective Action Unit 110: Area 3 RWMS U-3ax/bl Disposal Unit, Nevada Test Site, Nevada
This Closure Plan has been prepared for the Area 3 RWMS U-3ax/bl Disposal Unit Corrective Action Unit 110 in accordance with the Federal Facility and Consent Order (Nevada Division of Environmental Protection [NDEP] et al., 1996). The U-3ax/bl is a historic disposal unit within the Area 3 Radioactive Waste Management Site located on the Nevada Test Site (NTS). The unit, which was formed by excavating the area between two subsidence craters (U-3ax and U-3bl), was operationally closed in 1987. The U-3ax/bl disposal unit is scheduled for permanent closure under the Resource Conservation and Recovery Act as a hazardous waste landfill. Existing records indicate that, from July 1968 to December 1987, U-3ax/bl received 2.3 x 10{sup 5} cubic meters (8.12 x 10{sup 6} cubic feet) of waste. NTS nuclear device testing generated approximately 95 percent of the total volume disposed of in U-3ax/bl, the majority of which came from the Waste Consolidation Project (80 percent of the total volume) (Elletson and Johnejack, 1995). Area 3 is located in Yucca Flat, within the northeast quadrant of the NTS. The Yucca Flat watershed is a structurally closed basin encompassing an area of approximately 780 square kilometers (300 square miles). The structural geomorphology of …

Corrective Action Plan for Corrective Action Unit 261: Area 25 Test Cell A Leachfield System, Nevada Test Site, Nevada
This Corrective Action Plan (CAP) has been prepared for the Corrective Action Unit (CAU)261 Area 25 Test Cell A Leachfield System in accordance with the Federal Facility and Consent Order (Nevada Division of Environmental Protection [NDEP] et al., 1996). This CAP provides the methodology for implementing the approved corrective action alternative as listed in the Corrective Action Decision Document (U.S. Department of Energy, Nevada Operations Office, 1999). Investigation of CAU 261 was conducted from February through May of 1999. There were no Constituents of Concern (COCs) identified at Corrective Action Site (CAS) 25-05-07 Acid Waste Leach Pit (AWLP). COCs identified at CAS 25-05-01 included diesel-range organics and radionuclides. The following closure actions will be implemented under this plan: Because COCs were not found at CAS 25-05-07 AWLP, no action is required; Removal of septage from the septic tank (CAS 25-05-01), the distribution box and the septic tank will be filled with grout; Removal of impacted soils identified near the initial outfall area; and Upon completion of this closure activity and approval of the Closure Report by NDEP, administrative controls, use restrictions, and site postings will be used to prevent intrusive activities at the site.

DARHT-II Downstream Beam Transport Beamline
This paper describes the mechanical design of the downstream beam transport line for the second axis of the Dual Axis Radiographic Hydrodynamic Test (DARHT II) Facility. The DARHT-II project is a collaboration between LANL, LBNL and LLNL. DARHT II is a 20-MeV, 2000-Amperes, 2-{micro}sec linear induction accelerator designed to generate short bursts of x-rays for the purpose of radiographing dense objects. The downstream beam transport line is approximately 20-meter long region extending from the end of the accelerator to the bremsstrahlung target. Within this proposed transport line there are 15 conventional solenoid, quadrupole and dipole magnets; as well as several specialty magnets, which transport and focus the beam to the target and to the beam dumps. There are two high power beam dumps, which are designed to absorb 80-kJ per pulse during accelerator start-up and operation. Aspects of the mechanical design of these elements are presented.
