Debuncher Energy Mismatch (open access)

Debuncher Energy Mismatch

During the December 1999 startup of antiproton stacking, a quick measurement of the Debuncher momentum aperture was made. The measurement was done by turning off and de-tuning the Debuncher bunch rotation cavities and observing the Debuncher 75 MHz longitudinal schottky signal of the circulating antiprotons as shown in Figure 1. The frequency at the center of the plot corresponds to the rotation frequency of the Debuncher RF cavities. (The schottky signal and the bunch rotation frequency occur at the 127th and 90th harmonics of the revolution frequency, respectively.) Figure 1 shows that the Debuncher bunch rotation energy is offset from the middle of the Debuncher momentum aperture by about 0.7% (57 MeV). The measured value of momentum aperture using the width of the base of the signal shown in Figure 1 ({eta} = 0.006 ) is 3.9% (346 MeV). This is close to the design value of 4%, so the offset is probably not due to any asymmetric momentum aperture restrictions.

Separation of Tritium from Wastewater (open access)

Separation of Tritium from Wastewater

A proprietary tritium loading bed developed by Molecular Separations, Inc (MSI) has been shown to selectively load tritiated water as waters of hydration at near ambient temperatures. Tests conducted with a 126 {micro}C{sub 1} tritium/liter water standard mixture showed reductions to 25 {micro}C{sub 1}/L utilizing two, 2-meter long columns in series. Demonstration tests with Hanford Site wastewater samples indicate an approximate tritium concentration reduction from 0.3 {micro}C{sub 1}/L to 0.07 {micro}C{sub 1}/L for a series of two, 2-meter long stationary column beds Further reduction to less than 0.02 {micro}C{sub 1}/L, the current drinking water maximum contaminant level (MCL), is projected with additional bed media in series. Tritium can be removed from the loaded beds with a modest temperature increase and the beds can be reused Results of initial tests are presented and a moving bed process for treating large quantities of wastewaters is proposed. The moving bed separation process appears promising to treat existing large quantities of wastewater at various US Department of Energy (DOE) sites. The enriched tritium stream can be grouted for waste disposition. The separations system has also been shown to reduce tritium concentrations in nuclear reactor cooling water to levels that allow reuse. Energy requirements to …

Process Test Plan Shutdown P16 Exhauster

This Process Test Plan was written to gather temperature data to determine the amount of heat load remaining in tank 241-C-106. This process test plan is being conducted to gather the temperature data necessary to determine how much of the initial heat load is still left in 241-C-106. The heat load will be determined by shutting off the C-106 exhaust system, monitoring the change in tank temperature, and plugging the resulting data into the thermal model for this tank.

A simple extension of two-phase characteristic curves to include the dry region (open access)

A simple extension of two-phase characteristic curves to include the dry region

Two-phase characteristic curves are necessary for the simulation of water and vapor flow in porous media. Existing functions such as van Genuchten, Brooks and Corey, and Luckner et al. have significant limitations in the dry region as the liquid saturation goes to zero. This region, which is important in a number of applications including liquid and vapor flow and vapor-solid sorption, has been the subject of a number of previous investigations. Most previous studies extended standard capillary pressure curves into the adsorption region to zero water content and required a refitting of the revised curves to the data. In contrast, the present method provides for a simple extension of existing capillary pressure curves without the need to refit the experimental data. Therefore, previous curve fits can be used, and the transition between the existing fit and the relationship in the adsorption region is easily calculated. The data-model comparison shows good agreement. This extension is a simple and convenient way to extend existing curves to the dry region.

Thermal evaluation and performance of high-power Lithium-ion cells (open access)

Thermal evaluation and performance of high-power Lithium-ion cells

Under the sponsorship of the US Advanced Battery Consortium (USABC) and the Partnership for a New Generation of Vehicles (PNGV), Saft has developed high-power lithium-ion (Li-Ion) batteries for hybrid electric vehicles (HEVs). These high-power Li-Ion batteries are being evaluated for the US Department of Energy's (DOE) Hybrid Vehicle Propulsion Program. As part of this program, the National Renewable Energy Laboratory (NREL) characterized the thermal performance of the Saft (6-Ah) Li-Ion cells. The characterization included (1) obtaining thermal images of cells under a specified cycle, (2) measuring heat generation from the cells at various temperatures and under various charge/discharge profiles, and (3) determining the cells' capabilities for following a simulated power profile (driving cycle) at various initial states of charge and temperatures.

Continuum-based FEM modeling of ceramic powder compaction using a cap-plasticity constitutive model (open access)

Continuum-based FEM modeling of ceramic powder compaction using a cap-plasticity constitutive model

Common ceramic component manufacturing typically involves the processing of the raw materials in powder form. Granulated powder is formed into a green body of the desired size and shape by consolidation, often by simply pressing nominally dry powder. Ceramic powders are commonly pressed in steel dies or rubber bags with the aim of producing a near-net-shape green body for subsequent sintering. Density gradients in these compacts, introduced during the pressing operation, are often severe enough to cause distortions in the shape of the part during sintering due to nonuniform shrinkage. In such cases, green machining or diamond grinding operations may be needed to obtain the desired final shape and size part. In severe cases, nonuniform shrinkage may even cause fracture in the parts during sintering. Likewise, density gradients can result in green bodies that break during ejection from the die or that are too fragile to be handled during subsequent processing. Empirical relationships currently exist to describe powder compaction but provide little understanding of how to control die design or compaction parameters to minimize density gradients thereby forcing the designer to use expensive and time consuming trial and error procedures. For this reason, interest has grown in developing computational tools …
