Acceptance Test Plan for the Sludge Pickup Adaptor (open access)

Acceptance Test Plan for the Sludge Pickup Adaptor

This test plan documents the acceptance testing of the sludge pickup adapter for potential use during PSI Phases 3 and 4 fuel cleanliness inspection activities. The adaptex is attached to the strainer tip of the vacuum wand and used to suction up residual sludge captured in a sludge collection tray. The material is vacuumed into a chamber of known volume in the sludge pickup adapter. The device serves as an aid in helping to determine whether the observed quantity of sludge is within allowable limits (1.4 cm{sup 3} per fuel assembly). This functionality test involves underwater testing in the 305 Building Cold Test Facility to verify that sludge can be successfully vacuumed from a collection tray. Ancillary activities in this acceptance test include demonstration that the sludge pickup adapter CM be successfully attached to and detached from the vacuum wand underwater.

An agent-based microsimulation of critical infrastructure systems (open access)

An agent-based microsimulation of critical infrastructure systems

US infrastructures provide essential services that support the economic prosperity and quality of life. Today, the latest threat to these infrastructures is the increasing complexity and interconnectedness of the system. On balance, added connectivity will improve economic efficiency; however, increased coupling could also result in situations where a disturbance in an isolated infrastructure unexpectedly cascades across diverse infrastructures. An understanding of the behavior of complex systems can be critical to understanding and predicting infrastructure responses to unexpected perturbation. Sandia National Laboratories has developed an agent-based model of critical US infrastructures using time-dependent Monte Carlo methods and a genetic algorithm learning classifier system to control decision making. The model is currently under development and contains agents that represent the several areas within the interconnected infrastructures, including electric power and fuel supply. Previous work shows that agent-based simulations models have the potential to improve the accuracy of complex system forecasting and to provide new insights into the factors that are the primary drivers of emergent behaviors in interdependent systems. Simulation results can be examined both computationally and analytically, offering new ways of theorizing about the impact of perturbations to an infrastructure network.

Automated {sup 99}Tc analysis in AW-101 and AN-107 ``diluted feed'' matrixes (open access)

Automated {sup 99}Tc analysis in AW-101 and AN-107 ``diluted feed'' matrixes

A process monitor is needed by British Nuclear Fuels Limited, Inc. (BNFL Inc.) to measure total {sup 99}Tc levels in column effluents during technetium removal from the aqueous fraction of the Hanford high-level tank wastes. The monitor must achieve detection limits of 1 x 10{sup {minus}8}Ci/mL (0.6 {micro}g/mL). Measurements must be done in near real time, with an analysis frequency of {approximately}15 min. The monitoring technology must be sufficiently simple and robust for unattended continuous operation in the plant settings.

Constructing Material Interfaces from Data Sets with Volume-Fraction Information (open access)

Constructing Material Interfaces from Data Sets with Volume-Fraction Information

We present a new algorithm for material boundary interface reconstruction from data sets containing volume fractions. We transform the reconstruction problem to a problem that analyzes the dual data set, where each vertex in the dual mesh has an associated barycentric coordinate tuple that represents the fraction of each material present. After constructing the dual tetrahedral mesh from the original mesh, we construct material boundaries by mapping a tetrahedron into barycentric space and calculating the intersections with Voronoi cells in barycentric space. These intersections are mapped back to the original physical space and triangulated to form the boundary surface approximation. This algorithm can be applied to any grid structure and can treat any number of materials per element/vertex.

Development of the Instrumentation and Modeling for Heat Transfer Characteristics in CFBC (open access)

Development of the Instrumentation and Modeling for Heat Transfer Characteristics in CFBC

This technical report summarizes the research conducted and results obtained during the period beginning October 1, 1999 to March 31, 2000. Heat transfer characteristics study and experimental work were continued using the bench-scale CFB system with the heat transfer probe. A copper tube with thermocouples was used as the heat transfer probe which was convenient to measure the temperature changes at different locations of the bed. The heat transfer coefficient at different locations of the heat transferring surface decreases along the slides down the heat transfer surface; its temperature increase, which reducing the temperature difference between the surface of the tube and the bulk of the bed. The radial variation of heat transfer coefficients showed little increase in heat transfer coefficient near the wall. It is believed that a long heat-transferring surface is located in the core region; a boundary layer develops near the wall of the surface. This may cause clusters or streamers to form which slides down the surface. According to the results, heat transfer coefficients in the core region are not affected significantly by the location of the probe. The wall conduction resistance was eliminated and heat transfer coefficients were measured and calculated at different locations along …

Drip Shield Emplacement Gantry Concept (open access)

Drip Shield Emplacement Gantry Concept

This design analysis has shown that, on a conceptual level, the emplacement of drip shields is feasible with current technology and equipment. A plan for drip shield emplacement was presented using a Drip Shield Transporter, a Drip Shield Emplacement Gantry, a locomotive, and a Drip Shield Gantry Carrier. The use of a Drip Shield Emplacement Gantry as an emplacement concept results in a system that is simple, reliable, and interfaces with the numerous other exising repository systems. Using the Waste Emplacement/Retrieval System design as a basis for the drip shield emplacement concept proved to simplify the system by using existing equipment, such as the gantry carrier, locomotive, Electrical and Control systems, and many other systems, structures, and components. Restricted working envelopes for the Drip Shield Emplacement System require further consideration and must be addressed to show that the emplacement operations can be performed as the repository design evolves. Section 6.1 describes how the Drip Shield Emplacement System may use existing equipment. Depending on the length of time between the conclusion of waste emplacement and the commencement of drip shield emplacement, this equipment could include the locomotives, the gantry carrier, and the electrical, control, and rail systems. If the exisiting equipment …

The Federal Excise Tax on Gasoline and the Highway Trust Fund: A Short History (open access)

The Federal Excise Tax on Gasoline and the Highway Trust Fund: A Short History

Excise taxes have long been a part of our country's revenue history. In the field of gasoline taxation, the states led the way with Oregon enacting the first tax on motor fuels in 1919. By 1932, all states and the District of Columbia had followed suit with tax rates that ranged between two and seven cents per gallon. The federal government first imposed its excise tax on gasoline at a one cent per gallon rate in 1932. The gas tax was enacted to correct a federal budgetary imbalance.

Gravity-driven dense granular flows (open access)

Gravity-driven dense granular flows

The authors report and analyze the results of numerical studies of dense granular flows in two and three dimensions, using both linear damped springs and Hertzian force laws between particles. Chute flow generically produces a constant density profile that satisfies scaling relations suggestive of a Bagnold grain inertia regime. The type for force law has little impact on the behavior of the system. Failure is not initiated at the surface, consistent with the absence of surface flows and different principal stress directions at vs. below the surface.
