244-AR Vault Interim Stabilization Project Plan (open access)

244-AR Vault Interim Stabilization Project Plan

The 244-AR Vault Facility, constructed between 1966 and 1968, was designed to provide lag storage and treatment for the Plutonium-Uranium Extraction Facility (PUREX) tank farm sludges. Tank farm personnel transferred the waste from the 244-AR Vault Facility to B Plant for recovery of cesium and strontium. B Plant personnel then transferred the treatment residuals back to the tank farms for storage of the sludge and liquids. The last process operations, which transferred waste supporting the cesium/strontium recovery mission, occurred in April 1978. After the final transfer in 1978, the 244-AR facility underwent a cleanout. However, 2,271 L (600 gal) of sludge were left in Tank 004AR from an earlier transfer from Tank 241-AX-104. When the cleanout was completed, the facility was placed in a standby status. The sludge had been transferred to Tank 004AR to support Pacific Northwest National Laboratory [PNNL] vitrification work. Documentation of waste transfers suggests that a portion of the sludge may have been moved from Tank 004AR to Tank 002AR in preparation for transfer back to the AX Tank Farm; however, quantities of the sludge that were moved to Tank 002AR from that transfer must be estimated.

Aluminum R&D for Automotive Uses and the Department of Energy's Role (open access)

Aluminum R&D for Automotive Uses and the Department of Energy's Role

The use of aluminum in automotive applications is expanding. Aluminum offers a lower-weight alternative to steel, potentially increasing the efficiency of vehicles. However, the application of aluminum has been only in select areas of use, most notably cast aluminum in the engine, transmission, and wheels. Other areas offer the potential for growth that could significantly expand the amount of aluminum used in vehicles. Cost is the main barrier to increased aluminum use. Related to cost are aluminum production technologies that are not yet advanced enough to produce aluminum components at low enough price points for aluminum to compete with traditional automotive materials. Today's technologies require higher-priced alloys to be used for the components (e.g., closure panels), or have higher costs for needed processes (e.g., welding). In addition, new designs (e.g., spaceframes) are not well established for widespread use. R&D efforts are continuing to close these gaps. The U.S. Department of Energy (DOE) is helping to fund certain R&D projects that could provide breakthroughs in lowering costs for aluminum. This paper describes the current state of aluminum applications in vehicles, including its market penetration and opportunities. It also examines the cost structure of aluminum--from mining to final component use. By examining …

ANL calculational methodologies for determining spent nuclear fuel source term (open access)

ANL calculational methodologies for determining spent nuclear fuel source term

Over the last decade Argonne National Laboratory has developed reactor depletion methods and models to determine radionuclide inventories of irradiated EBR-II fuels. Predicted masses based on these calculational methodologies have been validated using available data from destructive measurements--first from measurements of lead EBR-II experimental test assemblies and later using data obtained from processing irradiated EBR-II fuel assemblies in the Fuel Conditioning Facility. Details of these generic methodologies are described herein. Validation results demonstrate these methods meet the FCF operations and material control and accountancy requirements.

Chemical Safety Management Program for Lockheed Martin Energy Systems operations at the Y-12 Plant (open access)

Chemical Safety Management Program for Lockheed Martin Energy Systems operations at the Y-12 Plant

Operated by Lockheed Martin Energy Systems (Energy Systems), the Department of Energy (DOE) Oak Ridge Y-12 Plant is a manufacturing facility that plays an integral role in the DOE nuclear weapons complex. Fulfilling the national security mission at the Y-12 Plant, continuing to be the cornerstone of uranium and lithium technologies for DOE, and providing customers with solutions for challenging manufacturing needs requires usage of a variety of chemicals and chemical processes. Performing this work safely while protecting workers, the public, and the environment is their commitment. The purpose of this document is to provide a description of the essential components of chemical safety, the integration of these components into the Y-12 Integrated Safety Management System (ISMS), and the functional integration of chemical safety issues across Y-12 organizations and programs managed by Energy Systems.

CLHEP -- New developments and directions (open access)

CLHEP -- New developments and directions

CLHEP is a broadly based collaboration, including developers at CERN, Cornell, FNAL, SLAC and elsewhere, to provide core C++ class libraries for the use of the HENP community. Recently, the collaboration aspect of CLHEP has been rejuvenated and expanded. To provide structure for the expanded collaboration, the developers have agreed to a consensus based organization centered around an editors list. An overview of the new structure, including the mechanism for ensuring CLHEP remains responsive to the needs of HENP users and other developers, will be presented. To guide directions of development, the nature of CLHEP has been clarified: The core CLHEP is structured as a set of packages which must have freely available sources and must be independent of external packages. These must work on at least a large fraction of the platforms in general use. The selection of these packages is driven by those needs and timetables of the High Energy and Nuclear Physics community which would not likely be met by code emerging from the general computing community. Coordination of CLHEP with other packages developed in HENP will be discussed, and recent and planned extensions to CLHEP will be presented.

A coupled Newton-Krylov solver for improved CHAD cache utilization and performance. (open access)

A coupled Newton-Krylov solver for improved CHAD cache utilization and performance.

CHAD (Computational Hydrodynamics for Advanced Design) is a computer program that has been developed to analyze flows in automotive and defense applications. Extensive performance analysis of the CHAD computer program indicated a need to address cache memory use to increase computational performance. Several strategies have been adopted to achieve this goal: simultaneous solution of the coupled Navier-Stokes equations, data clustering, and data ordering. A coupled Newton-Krylov solver has been incorporated into a version of the CHAD program, resulting in consistent improvement in run times that varies from 50% to 200%. Further work will be required to tune the solver for optimal performance. In addition, experiments with data cluster and reordering indicate a potential for performance improvement.

Forest Service Revenue-Sharing Payments: Legislative Issues

The Forest Service (FS) returns 25% of the revenues from each national forest to the states for use on roads and schools in counties where the forests are located; the Bureau of Land Management shares 50% of its revenues with counties containing the Oregon & California grant lands. This report discusses the legislative concerns that have arisen because declining timber sales have reduced revenues.

How far from stability can we go using Gammasphere and the ANL fragment mass analyzer? (open access)

How far from stability can we go using Gammasphere and the ANL fragment mass analyzer?

Gammasphere is the pre-eminent detector for gamma-ray spectroscopy studies in the United States. The device consists of up to 110 Compton-Suppressed Ge detectors, and offers excellent energy resolution (2.3 keV at 1 MeV) and an order of magnitude increase in photopeak efficiency over previous Ge-arrays (10% at 1 MeV). Since early January 1998, Gammasphere has begun a cycle of experiments at the ATLAS accelerator at Argonne National Laboratory. As of this writing, 100 experiments have been carried out. A subset of these experiments have utilized Gammasphere coupled to the Fragment Mass Analyzer (FMA), a high resolution mass spectrometer which transports reaction products produced at the target position and disperses them by their mass/charge ratio at the focal plane. This presentation will highlight some of the physics issues being addressed by the utilization of these two devices in tandem. More specifically, experiments directed at studying; (1) N-Z nuclei at the edges of stability, (2) the properties of excited states in proton emitters, and (3) the stability and shapes of very heavy nuclei will be presented.
