The purpose of the transport methodology and component analysis is to provide the numerical methods for simulating radionuclide transport and model setup for transport in the unsaturated zone (UZ) site-scale model. The particle-tracking method of simulating radionuclide transport is incorporated into the FEHM computer code and the resulting changes in the FEHM code are to be submitted to the software configuration management system. This Analysis and Model Report (AMR) outlines the assumptions, design, and testing of a model for calculating radionuclide transport in the unsaturated zone at Yucca Mountain. In addition, methods for determining colloid-facilitated transport parameters are outlined for use in the Total System Performance Assessment (TSPA) analyses. Concurrently, process-level flow model calculations are being carrier out in a PMR for the unsaturated zone. The computer code TOUGH2 is being used to generate three-dimensional, dual-permeability flow fields, that are supplied to the Performance Assessment group for subsequent transport simulations. These flow fields are converted to input files compatible with the FEHM code, which for this application simulates radionuclide transport using the particle-tracking algorithm outlined in this AMR. Therefore, this AMR establishes the numerical method and demonstrates the use of the model, but the specific breakthrough curves presented do not …

This presentation investigates the incorporation of uncertainty and variability of drip shield and waste package degradation in analyses with the Waste Package Degradation (WAPDEG) program (CRWMS M&O 1998). This plan was developed in accordance with Development Plan TDP-EBS-MD-000020 (CRWMS M&O 1999a). Topics considered include (1) the nature of uncertainty and variability (Section 6.1), (2) incorporation of variability and uncertainty into analyses involving individual patches, waste packages, groups of waste packages, and the entire repository (Section 6.2), (3) computational strategies (Section 6.3), (4) incorporation of multiple waste package layers (i.e., drip shield, Alloy 22, and stainless steel) into an analysis (Section 6.4), (5) uncertainty in the characterization of variability (Section 6.5), and (6) Gaussian variance partitioning (Section 6.6). The presentation ends with a brief concluding discussion (Section 7).

Monitoring of geologic sequestration projects will require the measurement of many different parameters and processes at many different locations at the surface and in the subsurface. The greatest need for technology development is for monitoring of processes in the subsurface in the region between wells. The approach to fitting this need is to build upon decades of experience in use of geophysics in the oil and gas industry. These methods can be optimized for CO2 monitoring, and customized and extended in order to meet the need for cost-effective methods applicable to saline disposal sites, coal bed methane sites, as well as oil and gas reservoir sequestration sites. The strategy for development of cost-effective methods follows a three step iterative process of sensitivity analysis using numerical and experimental techniques, field testing at a range of scale in different formations, and analysis and integration of complimentary types of data.

ACTS flow loop is now operational under elevated pressure and temperature. Currently, experiments with water under pressure and temperature are being conducted. Based on the analysis of Fann 70 data, empirical correlations defining the shear stress as a function of temperature, pressure and the shear rate have been developed for Petrobras synthetic drilling fluids. PVT equipment has been modified for testing Synthetic drilling fluids. Initial calibration tests have been conducted by using water. Currently, the base oil of the Petrobras synthetic drilling fluid is being tested. Foam flow experiments have been conducted. Currently, more experiments are being conducted while data are being analyzed to characterize the rheology of the foam. Cuttings transport experiments have been conducted using air, water and cuttings. Preliminary results have shown that it may not be possible to avoid cuttings bed deposition under any practical combination of air and water flow rates. Foam stability analyses have been conducted. Effects of salt and oil concentration on the foam stability have been investigated. A software for controlling the data sampling and data storage during cuttings monitoring process have been developed.

This evaluation was grouped under two categories described as Cask Loadout System (CLS) and Cranes/Other Modifications.

The objective of this project is to develop a method to predict the potential reliability of software to be used in a digital system instrumentation and control system. The reliability prediction is to make use of existing measures of software reliability such as those described in IEEE Std 982 and 982.2. This prediction must be of sufficient accuracy to provide a value for uncertainty that could be used in a nuclear power plant probabilistic risk assessment (PRA). For the purposes of the project, reliability was defined to be the probability that the digital system will successfully perform its intended safety function (for the distribution of conditions under which it is expected to respond) upon demand with no unintended functions that might affect system safety. The ultimate objective is to use the identified measures to develop a method for predicting the potential quantitative reliability of a digital system. The reliability prediction models proposed in this report are conceptual in nature. That is, possible prediction techniques are proposed and trial models are built, but in order to become a useful tool for predicting reliability, the models must be tested, modified according to the results, and validated. Using methods outlined by this project, …

During this quarter, in task area 1, work was performed on three separate areas of activity. These were (1) review of the proposed and final EPA Tier 2 regulations, (2) assistance in preparation of an ultra-clean transportation fuels report for the deputy assistant secretary for Fossil Energy, (3) preparation of a detailed trip report from attending the Clean Fuels 2000 conference in San Diego. In task area 4, three activities were undertaken: an update of coproduction, an analysis of the potential for gasification of petroleum coke in U.S. refineries, and preparation and presentation of a paper at the Coal Utilization and Fuel Systems conference in Clearwater. In task area 5, a presentation was prepared for the American Association of Petroleum Geologists (AAPG) Annual Convention to be held in New Orleans in April. This presentation was an overview of GTL technology including the current costs and product values. In addition the potential risks of the technology were addressed and the potential contribution of GTL products to the future world fuel market was discussed.

There may be several manufacturers or models that meet the critical characteristics for any one item.

We are compiling a list of anticipated target spot sizes that are specified by the NIF users groups. This data will be used to anticipate demands for phase plates. The spot size also has an impact on the laser operation. Presently the phase plates are designed to sit in the leo section of the FOA (before the conversion crystals). Intensity modulations produced by the phase plates are nonlinearly proportional to the laser spot size. For spot sizes above 3 mm diameter, the intensity modulations are large enough that the damage threshold for the remainder of the FOA is exceeded. For experiments requiring spot diameters larger than 3 ram, it is suggested that the phase plates sit in the 3{omega} section of the FOA. For planning purposes, the cost of the 3{omega} phase plates is presently projected to be more than that of a le0 phase plate due to the use of inclusion-free fused silica as the substrate material, This report is a summary of a meeting that we had on February 16, 2000 in order to catalogue the possible range of requested NIF spot sizes. Copies of the viewgraphs which were presented are also included.

Creep of zirconium and zirconium alloys has been labeled ''anomalous.'' Researchers often report that zirconium and its alloys never reach true steady state creep and have stress exponents that continuously change with stress and temperature. Many varied interpretations have been offered explaining the creep behavior of zirconium. Some have suggested that creep is diffusion controlled, while others maintain that creep is dislocation glide controlled. Cumulative zirconium creep data will be presented based on an extensive literature review. An interpretation of results will be presented and compared to previous interpretations.

DOE Policy 450.4 mandates that safety be integrated into all aspects of the management and operations of its facilities. The goal of an institutionalized Integrated Safety Management System (ISMS) is to have a single integrated system that includes Environment, Safety, and Health requirements in the work planning and execution processes to ensure the protection of the worker, public, environment, and the federal property over the life cycle of the Environmental Restoration (ER) Project. The purpose of this Environmental Restoration Contractor (ERC) ISMS Phase MI Verification was to determine whether ISMS programs and processes were institutionalized within the ER Project, whether these programs and processes were implemented, and whether the system had promoted the development of a safety conscious work culture.

A model of energy gain induced by fast ignition of thermonuclear burn in compressed deuterium-tritium fuel, is used to show the potential for 300x gain with a driver energy of 1 M J, if the National Ignition Facility (NIF) were to be adapted for fast ignition. The physics of fast ignition has been studied using a petawatt laser facility at the Lawrence Livermore National Laboratory. Laser plasma interaction in a preformed plasma on a solid target leads to relativistic self-focusing evidenced by x-ray images. Absorption of the laser radiation transfers energy to an intense source of relativistic electrons. Good conversion efficiency into a wide angular distribution is reported. Heating by the electrons in solid density CD{sub 2} produces 0.5 to 1/keV temperature, inferred from the D-D thermo-nuclear neutron yield.

Scientists from the Lawrence Berkeley National Laboratory (Berkeley Lab) have generated 300-femtosecond pulses of bend-magnet synchrotron radiation at the Advanced Light Source (ALS) with the aid of a laser ''time-slicing'' technique. This technique allows an ultrashort portion of an electron bunch in the ALS storage ring to be spatially displaced in such a way that the synchrotron radiation from the displaced portion can then be collected separately. Their proof-of-principle experiment demonstrates that this technique is a viable one for producing ultra-short pulses of x-rays. An ALS bend-magnet beamline is already under construction that will be dedicated to time-resolved x-ray diffraction, EXAFS, and other techniques capable of probing the long-range and local structure of matter on a femtosecond time scale. A proposed undulator beamline based on the same technique would further enhance the flux and brightness by orders of magnitude.

The purpose of this document is to establish the facility Authorization Envelope (AE) for the 300 Liquid Effluent Facilities (LEP )Project and identify the requirements related to the maintenance of the AE as Specified in HNF-PRO-2701, Authorization Envelope and Authorization Agreement.

The AE documents the limits of operations for all 300 LEF Project activities.

Blue light emitting devices (LEDs) are rapidly becoming an increasingly important technology underscored by intense world-wide research and development. Blue emitter technology is the cornerstone for crucial applications that include full-color flat panel displays, ultra-high density optical memories and data storage, back lighting, and chemical and biological sensing. Currently, the GaN material system dominate the field of blue emitters, which in turn is dominated by Japanese researchers. However, critical obstacles remain for this material system. Growth-related defects, which arise from lattice-matching problems, degrade the device and limits operational lifetimes. Blue GaN diodes produced in Japan presently operate for the longest time. Those produced in the US have significantly shorter lifetimes.

A nonradioactive chemical vapor space source term for tanks on the Phase 1 and the extended Phase 1 delivery, storage, and disposal mission was determined.

This specification establishes the performance requirements and provides the references to the requisite codes and standards to he applied during the design of the Double-Shell Tank (DST) Utilities Subsystems that support the first phase of waste feed delivery (WFD). The DST Utilities Subsystems provide electrical power, raw/potable water, and service/instrument air to the equipment and structures used to transfer low-activity waste (LAW) and high-level waste (HLW) to designated DST staging tanks. The DST Utilities Subsystems also support the equipment and structures used to deliver blended LAW and HLW feed from these staging tanks to the River Protection Project (RPP) Privatization Contractor facility where the waste will be immobilized. This specification is intended to be the basis for new projects/installations. This specification is not intended to retroactively affect previously established project design criteria without specific direction by the program.

The U.S. Department of Energy (DOE), in accordance with the Strom Thurmond National Defense Authorization Act for Fiscal Year 1999, established the Office of River Protection (ORP) to successfully execute and manage the River Protection Project (RPP), formerly known as the Tank Waste Remediation System (TWRS). The mission of the RPP is to store, retrieve, treat, and dispose of the highly radioactive Hanford tank waste in an environmentally sound, safe, and cost-effective manner. The team shown in Figure 1-1 is accomplishing the project. The ORP is providing the management and integration of the project; the Tank Farm Contractor (TFC) is responsible for providing tank waste storage, retrieval, and disposal; and the Privatization Contractor (PC) is responsible for providing tank waste treatment.
