The electron beam technology demonstration at SRS has potential benefit to some groundwater remediation projects at SR and other DOE facilities. At SRS, organic contaminants are the most commonly found contaminants in groundwaters, consequently, this technology has the potential to remove the contaminants fro the groundwaters effectively. The primary objective is to provide site-specific data to support SRS remediation actions. The secondary objective for the technology demonstration will be to obtain necessary information for a full-scale remediation treatment system. The information will include operating and construction costs, removal efficiency, potential operating problems, and process chemical dosages if applied.

Pacific Northwest Laboratory (PNL) is developing a borosilicate glass as a solid, stable medium for the disposal of high-level radioactive waste at the Hanford site. They are optimizing the glass forming region and developing process models to be used in the Hanford Waste Verification Project (HWVP). Their experimentally-based statistical approach for optimizing the glass composition for HWVP has been designated the Composition Variability Study (CVS). In Part 1 of the CVS study PNL tested wide ranges of composition developed first-order empirical models, and provided input for planning CVS-2. In part 2, they are generating glass property data for a number of compositions in order to develop second-order empirical models which will be used to identify the composition region that simultaneously satisfies all quality and processability requirements of HWVP.

Hydrogen piston engines can be simultaneously optimized for improved thermal efficiency and for extremely low emissions. Using these engines in constant-speed, constant-load systems such as series hybrid-electric automobiles or home cogeneration systems can result in significantly improved energy efficiency. For the same electrical energy produced, the emissions from such engines can be comparable to those from natural gas-fired steam power plants. These hydrogen-fueled high-efficiency, low-emission (HELE) engines are a mechanical equivalent of hydrogen fuel cells. HELE engines could facilitate the transition to a hydrogen fuel cell economy using near-term technology.

Abstracts are presented of 63 papers on the following topics: large-scale optimization, interior-point methods, algorithms for optimization, problems in control, network optimization methods, and parallel algorithms for optimization problems.
