Addendum to the performance assessment analysis for low-level waste disposal in the 200 west area active burial grounds (open access)

Addendum to the performance assessment analysis for low-level waste disposal in the 200 west area active burial grounds

An addendum was completed to the performance assessment (PA) analysis for the active 200 West Area low-level solid waste burial grounds. The addendum includes supplemental information developed during the review of the PA analysis, an ALARA analysis, a comparison of PA results with the Hanford Groundwater Protection Strategy, and a justification for the assumption of 500 year deterrence to the inadvertent intruder.

Estimating the Extent and Thickness of DNAPL within the A/M Area of the Savannah River Site (open access)

Estimating the Extent and Thickness of DNAPL within the A/M Area of the Savannah River Site

The objective of this study is to refine the current conceptual model for the extent, character, and thickness of DNAPL contamination in the A/M Area. The evaluation is based upon historical records of operations and waste management and on detailed screening of historical groundwater concentrations against solubility limits. The topology of the Green Clay confining zone is used as the primary factor determining DNAPL pool thickness and resulting migration paths.

Free surface rise and fall due to wall turbulent structures (open access)

Free surface rise and fall due to wall turbulent structures

Turbulent structures near the wall and the the surface have been studied in open channel flows using oxygen bubble visualization techniques. Experiments indicate that the flow is dominated by the generation of wall ejections and interactions of such structures with the free surface. The ejections are seen to evolve near the wall, reach the free surface, form surface patches, roll back and mix into the bulk flow. Furthermore, there are evidence of ``horseshoe`` and ``hockeystick`` type vortices in relation to the bursting events. Measurements of surface characteristics show that the ejection-inflow events are associated with deformation of the free surface. It is seen that as ejections reach the free surface, the surface goes through a rise, whereas the surface falls when the inflowing fluid returns toward the wall. These effects are enhanced as the flow Reynolds number is increased.

In situ calibration of the CMS HCAL detector (open access)

In situ calibration of the CMS HCAL detector

One serious challenge for hadron calorimeters is setting the absolute calibration. Electromagnetic calorimeters in a magnetic spectrometer have the momentum of electrons to calibrate against. In addition, at hadron colliders, Z supplies a narrow resonance to determine calibrations. No such well-measured processes have been available in the past for hadron calorimeters. In high energy collisions, high Pt hadrons are not normally isolated, rather appearing as part of jets. Contamination of the energy scale by unmeasured neutrals or by leakage from adjacent particles is always a concern. There are low cross section processes that possess jets of well understood energy, for example a high pt Z recoiling off of a single jet. The high energy and luminosity of the LHC may supply enough of these events for quantities useful for calibration. In this paper we outline the possibility for doing in situ calibration using Z recoiling off of a jet events, and {ital t{anti t}} events. We also comment on the more conventional possibilities of using muons and energy-flow to calibrate.

Optimum flywheel sizing for parallel and series hybrid vehicles (open access)

Optimum flywheel sizing for parallel and series hybrid vehicles

Flywheels have the possibility of providing high turnaround efficiency and high specific power output. These characteristics are very important for the successful manufacture of parallel and series hybrid vehicles, which have the potential for providing high fuel economy and very low emissions with range and performance comparable to today`s light-duty vehicles. Flywheels have a high specific power output, but relatively low specific energy output. Therefore, it is of importance to determine energy and power requirements for flywheels applied to light-duty vehicles. Vehicle applications that require an energy storage system with high power and low energy are likely to benefit from a flywheel. In this paper, a vehicle simulation code and a flywheel model are applied to the calculation of optimum flywheel energy storage capacity for a parallel and a series hybrid vehicle. A conventional vehicle is also evaluated as a base-case, to provide an indication of the fuel economy gains that can be obtained with flywheel hybrid vehicles. The results of the analysis indicate that the optimum flywheel energy storage capacity is relatively small. This results in a low weight unit that has a significant power output and high efficiency. Emissions generated by the hybrid vehicles are not calculated, but …
