A 2-D Self-Consistent DSMC Model for Chemically Reacting Low Pressure Plasma Reactors (open access)

A 2-D Self-Consistent DSMC Model for Chemically Reacting Low Pressure Plasma Reactors

This paper will focus on the methodology of using a 2D plasma Direct Simulation Monte Carlo technique to simulate the species transport in an inductively coupled, low pressure, chemically reacting plasma system. The pressure in these systems is typically less than 20 mtorr with plasma densities of approximately 10{sup 17} {number_sign}/m{sup 3} and an ionization level of only 0.1%. This low ionization level tightly couples the neutral, ion, and electron chemistries and interactions in a system where the flow is subsonic. We present our strategy and compare simulation results to experimental data for Cl{sub 2} in a Gaseous Electronics Conference (GEC) reference cell modified with an inductive coil.

300 Area waste acid treatment system closure plan (open access)

300 Area waste acid treatment system closure plan

The Hanford Facility Dangerous Waste Permit Application is considered to be a single application organized into a General Information Portion (document number DOERL-91-28) and a Unit-Specific Portion. The scope of the Unit-Specific Portion includes closure plan documentation submitted for individual, treatment, storage, and/or disposal units undergoing closure, such as the 300 Area Waste Acid Treatment System. Documentation contained in the General Information Portion is broader in nature and could be used by multiple treatment, storage, and/or disposal units (e.g., the glossary provided in the General Information Portion). Whenever appropriate, 300 Area Waste Acid Treatment System documentation makes cross-reference to the General Information Portion, rather than duplicating text. This 300 Area Waste Acid Treatment System Closure Plan (Revision 2) includes a Hanford Facility Dangerous Waste Permit Application, Part A, Form 3. Information provided in this closure plan is current as of April 1999.

Advanced Polymer PV System; PVMaT 4A1 Final Report; September 1995 - December 1997 (open access)

Advanced Polymer PV System; PVMaT 4A1 Final Report; September 1995 - December 1997

This document reports on work performed by Evergreen Solar, Inc. under this Photovoltaic Manufacturing Technology (PVMaT) subcontract. The purpose of this subcontract was to produce lower module and systems costs through the innovative use of polymeric materials. The impetus behind this approach was the burgeoning use of polymers in such major industries as packaging and automobiles. The market demand in these industries has resulted in whole new areas of high-performance, but low-cost, plastics. These developments created fresh opportunities for photovoltaics. Using this approach, a new backskin material instead of Tedlar{trademark} (Tedlar is a Dupont trademark) or Tedlar{trademark} laminate was developed and tested. This new backskin material allowed us to make a frameless module and novel mounting methods. The latter is referred to as an Innovative Mounting System (IMS). This IMS system, in conjunction with the frameless module, substantially reduces the cost of installed PV systems by reducing labor and materials costs, both in the factory and in field installation. The IMS incorporates several advances in polymers, processing methods, and product design. The advanced backskin material permits elimination of the conventional aluminum perimeter frame, serves to protect and seal the module edge, and allows for direct bonding of multi-functional mounting bars. …

ALARA{trademark} 1146 strippable coating (open access)

ALARA{trademark} 1146 strippable coating

Strippable or temporary coatings are innovative technologies for decontamination that effectively reduce loose contamination at low cost. These coatings have become a viable option during the deactivation and decommissioning of both US Department of Energy (DOE) and commercial nuclear facilities to remove or fix loose contamination on both vertical and horizontal surfaces. The ALARA{trademark} 1146 strippable coating was demonstrated as part of the Savannah River Site LSDDP and successfully removed transferable (surface) contamination from multiple surfaces (metal and concrete) with an average decontamination factor for alpha contamination of 6.68 and an average percentage of alpha contamination removed of 85.0%. Beta contamination removed was an average DF of 5.55 and an average percentage removed of 82.0%. This paper is an Innovative Technology Summary Report designed to provide potential users with the information they need to quickly determine if a technology would apply to a particular environmental management problem. They also are designed for readers who may recommend that a technology be considered by prospective users. This Innovative Technology offers a 35% cost savings over the Baseline Technology.

Alternative Fuel News, Vol. 2, No. 6

The cover story in this issue of the Alternative Fuel News highlights the niche market principle; the places in which AFVs would best fit. This year's SEP funding is expected to be the springboard needed for the development of niche projects. The Clean Cities Program, by matching those needs and attributes in niches, can dramatically increase the attractiveness of AFVs and make an impact on those high-mileage, high-use fleets.
