Influence of faults on groundwater flow and transport at YuccaMountain, Nevada (open access)

Influence of faults on groundwater flow and transport at YuccaMountain, Nevada

Numerical simulations of groundwater flow at Yucca Mountain, Nevada are used to investigate how faults influence groundwater flow pathways and regional-scale macrodispersion. The 3-D model has a unique grid block discretization that facilitates the accurate representation of the complex geologic structure present in faulted formations. Each hydrogeologic layer is discretized into a single layer of irregular and dipping grid blocks, and faults are discretized such that they are laterally continuous and varied in displacement varies along strike. In addition, the presence of altered fault zones is explicitly modeled, as appropriate. Simulations show that upward head gradients can be readily explained by the geometry of hydrogeologic layers, the variability of layer permeabilities, and the presence of permeable fault zones or faults with displacement only, not necessarily by upwelling from a deep aquifer. Large-scale macrodispersion results from the vertical and lateral diversion of flow near the contact of high- and low-permeability layers at faults, and from upward flow within high-permeability fault zones. Conversely, large-scale channeling can occur as a result of groundwater flow into areas with minimal fault displacement. Contaminants originating at the water table can flow in a direction significantly different from that of the water table gradient, and isolated zones …

Water-Level Monitoring Plan for the Hanford Groundwater Monitoring Project (open access)

Water-Level Monitoring Plan for the Hanford Groundwater Monitoring Project

This document presents the water-level monitoring plan for the Hanford Groundwater Monitoring Project, conducted by the Pacific Northwest National Laboratory (PNNL). Water-level monitoring of the groundwater system beneath the Hanford Site is performed to fulfill the requirements of various state and federal regulations, orders, and agreements. The primary objective of this monitoring is to determine groundwater flow rates and directions. To meet this and other objectives, water-levels are measured annually in monitoring wells completed within the unconfined aquifer system, the upper basalt-confined aquifer system, and in the lower basalt-confined aquifers for surveillance monitoring. At regulated waste units, water levels are taken monthly, quarterly, semi-annually, or annually, depending on the hydrogeologic conditions and regulatory status of a given site. The techniques used to collect water-level data are described in this document, along with the factors that affect the quality of the data and the strategies employed by the project to minimize error in the measurement and interpretation of water levels.

Intermittent single point machining of brittle materials (open access)

Intermittent single point machining of brittle materials

A series of tests were undertaken to explore diamond tool wear in the intermittent cutting of brittle materials, specifically silicon. The tests were carried out on a plain way No. 3 Moore machine base equipped as a flycutter with a motorized Professional Instruments 4R air bearing spindle. The diamond tools were made by Edge Technologies with known crystal orientation and composition and sharpened with either an abrasive or chemical process, depending on the individual test. The flycutting machine configuration allowed precise control over the angle at which the tool engages the anisotropic silicon workpiece. In contrast, the crystallographic orientation of the silicon workpiece changes continuously during on-axis turning. As a result, it is possible to flycut a workpiece in cutting directions that are known to be easy or hard. All cuts were run in the 100 plane of the silicon, with a slight angle deliberately introduced to ensure that the 100 plane is engaged in ''up-cutting'' which lengthens the tool life. A Kistler 9256 dynamometer was used to measure the cutting forces in order to gain insight into the material removal process and tool wear during testing. The dynamometer provides high bandwidth force measurement with milli-Newton resolution and good thermal …

Analysis of a Lifting Fixture to Hold a Steel Mandrel Horizontally from one End Support (open access)

Analysis of a Lifting Fixture to Hold a Steel Mandrel Horizontally from one End Support

A lifting fixture (drawing number 3823.113-MD-372382) that lifts large steel mandrels from one end through the mandrel's end support web is described. The mandrels are used as a mold to form carbon fiber cylinders. The mandrels are held from one end to allow the carbon cylinder to be pulled horizontally off the mandrel. Only mandrels as described in drawing numbers 3823.113-MD-358992 and 3823.1 13-MD-358994 are lifted by the fixture. The largest mandrel is 41 inches in diameter, 120 inches long, and weighs approximately 3,000 lbs. A detailed procedure for removing the carbon cylinder from the steel mandrel is given in the Appendix. The fixture is to be supported only using Fermilab Forklift 10207 or equivalent. The forklift has a nameplate capacity of 12,000 lbs 24 inches from the mast at an elevation of 130 inches from the floor. The forklift forks must be removed from the truck prior to using the fixture. The forklift is to be used to support the mandrels only during the lifting operation and is not to be used to transport the mandrels. Stresses at the lifting fixture are shear stresses on the support brackets due to the overall weight of the mandrel and moment loads …

Retrospective application of online catalog author authority control: A pilot project (open access)

Retrospective application of online catalog author authority control: A pilot project

A total of 56 author authority records were created or revised in the Fermilab online catalog. An example of a correct author authority record is given. Since the author authority records used 400 fields and thus pipe all the variant names to the one record, any additions of records with any of these variants will be handled by the online catalog. It is likely that we have included most of the common variants of key Fermilab authors' names, so the database should stay cleaner and more functional for years to come. This project was a success. Therefore an immediate future plan is to implement additional author authority records for the remainder of the authors in the database. Afterwards, authority maintenance should be built in to Library work processes as an ongoing task.

Engineering Basis Document Review for Waste Feed Delivery from Single Shell Tanks (SST) (open access)

Engineering Basis Document Review for Waste Feed Delivery from Single Shell Tanks (SST)

This report provides the results of a review conducted on existing operating specifications and safety requirements and provides a summary of applicable design constraints on the Single-Shell Tank (SST) System. The SST System is required to transition from the current waste storage mission to support the Tank Waste Remediation System (TWRS) waste retrieval mission described in the Tank Waste Remediation System Mission Analysis Report (Acree 1998). The SST System is also required to support the Project Hanford Management Contract (PHMC) portions of the Waste Feed Delivery (WFD) mission. In Phase 1 the SST System will be required to retrieve waste from selected SSTs (tanks 241-C-102 and 241-C-104) for transfer to the Double-Shell Tank (DST) System (tanks 241-AZ-101,241-AY-102). The SST System will include all the systems, structures and components required to safely store, retrieve, and transfer waste in support of the TWRS mission. Operational Specification Documents (OSDs) govern operation of the existing SST System components. However, the system will be highly modified to support the TWRS mission. Therefore OSD requirements may not apply to the new system's design. This document describes the review of existing SST OSDs and provides the rationale for selecting or rejecting requirements as constraints on the SST …

Hindered Diffusion of Asphaltenes at Elevated Temperature and Pressure Progress Report (open access)

Hindered Diffusion of Asphaltenes at Elevated Temperature and Pressure Progress Report

During this time period, experiments were performed to study the diffusion controlled uptake of quinoline and a coal asphaltene into porous carbon catalyst pellets. Cyclohexane and toluene were used as solvents for quinoline and the coal asphaltene respectively. The experiments were performed at 27 C and 75 C, at a pressure of 250 psi (inert gas) for the quinoline/cyclohexane system. For the coal asphaltene/toluene system, experiments were performed at 27 C, also at a pressure of 250 psi. These experiments were performed in a 20 cm{sup 3} microautoclave, the use of which is advantageous since it is economical from both a chemical procurement and waste disposal standpoint due to the small quantities of solvents and catalysts used. A C++ program was written to simulate data using a mathematical model which incorporated both diffusional and adsorption mechanisms. The simulation results showed that the mathematical model satisfactorily fitted the adsorptive diffusion of quinoline and the coal asphaltene onto a porous activated carbon. For the quinoline/cyclohexane system, the adsorption constant decreased with an increase in temperature. The adsorption constant for the coal asphaltene/toluene system at 27 C was found to be much higher than that of the quinoline/cyclohexane system at the same temperature. …

Lifetime studies at the APS. (open access)

Lifetime studies at the APS.

The studies presented in this note are focused on the lifetime characterization with positrons for the symmetrical low {beta}{sub y} lattice. Before switching back to electrons, detailed lifetime studies were performed in order to gather data that could be compared to similar ones with electrons, the ultimate goal being to define a model that could be used to predict lifetimes. The report is divided into three parts: simulations to allow decoupling of the different contributions to the lifetime; review of the experimental conditions and related problems; and analysis of the data and discussion of the limitations.
