The Hanford Site Integrated Pest Management Plan (HSIPMP) defines the Integrated Pest Management (IPM) decision process and subsequent strategies by which pest problems are to be solved at all Hanford Site properties per DOE-RL Site Infrastructure Division memo (WHC 9505090). The HSIPMP defines the roles that contractor organizations play in supporting the IPM process. In short the IPM process anticipates and prevents pest activity and infestation by combining several strategies to achieve long-term pest control solutions.

The CRS report describes the battle with natural gas companies on helium gas, being wasted, and released into the environment. Incentives were put in place for natural gas companies sell this helium to the government and for it to be stored in a government facility. Consequently, this also brought up controversy for why funding is being used to store a surplus of helium. Congress would debate on whether government involvement was the best option and a consensus was reached to fund the National Academy of Science to find the best way to dispose of the helium. Their results of their studies and the H.R. 4168 bill that was passed are also described.

Toxicological consequences were calculated for a postulated maximum caustic soda (NaOH) solution spray leak during addition to a waste tank to adjust tank pH. Although onsite risk guidelines were exceeded for the unmitigated release, site boundary consequences were below the level of concern. Means of mitigating the release so as to greatly reduce the onsite consequences were recommended. Consequences for the mitigated release were estimated and both onsite and offsite consequences were found to negligible.

The development of coal-fired magnetohydrodynamic (MHD) power can be viewed as consisting of two parts; the topping cycle and the bottoming cycle. The topping cycle consists of the coal combustor, MHD generator and associated components. The bottoming cycle consists of the heat recovery, steam generation, seed recovery/regeneration, emissions control (gas and particulate), ash handling and deposition, and materials evaluation. The report concentrates on the bottoming cycle, for which much of the technology was developed at the University of Tennessee Space Institute (UTSI). Because of the complexity of the required technology, a number of issues required investigation. Of specific concern regarding the bottoming cycle, was the design of the steam cycle components and emissions control. First, the high combustion temperatures and the use of large quantities of potassium in the MHD combustor results in a difference in the composition of the gases entering the bottoming cycle compared to conventional systems. Secondly, a major goal of the UTSI effort was to use a variety of coals in the MHD system, especially the large reserves of high-sulfur coals available in the United States.

The purpose of this paper is to discuss the issues involved with, and the results from, testing of two example programs that use PVODE: pvkx and pvnx. These two programs are intended to provide a template for users for follow when writing their own code. However, we also used them (primarily pvkx) to do performance testing and visualization. This work was done on a Cray T3D, a Sparc 10, and a Sparc 5.

The first objective is to utilize reservoir characterization and advanced technologies to optimize the design of a carbon dioxide (CO{sub 2}) project for the South Cowden Unit (SCU) located in Ector County, Texas. The SCU is a mature, relatively small, shallow shelf carbonate unit nearing, waterflood depletion. The second objective is to demonstrate the performance and economic viability of the project in the field. This report includes work on the reservoir characterization and project design objective and the demonstration project objective.

Preparations are under way to sell the sodium stored in the 1720-DR tank in the 1720-DR building. This will require that the tank, as well as the 1720-DR facility, be moved to the 300 Area, so that the sodium may be melted and transferred into a railroad tanker car. Because the sodium is a hazardous material and is being shipped in a nonspecification packaging, a safety evaluation for packaging (SEP) is required. This SEP approves the sodium-filled tank for a single shipment from the 105-DR area to the 300 Area.

This paper considers the protein structure prediction problem for lattice and off-lattice protein folding models that explicitly represent side chains. Lattice models of proteins have proven extremely useful tools for reasoning about protein folding in unrestricted continuous space through analogy. This paper provides the first illustration of how rigorous algorithmic analyses of lattice models can lead to rigorous algorithmic analyses of off-lattice models. The authors consider two side chain models: a lattice model that generalizes the HP model (Dill 85) to explicitly represent side chains on the cubic lattice, and a new off-lattice model, the HP Tangent Spheres Side Chain model (HP-TSSC), that generalizes this model further by representing the backbone and side chains of proteins with tangent spheres. They describe algorithms for both of these models with mathematically guaranteed error bounds. In particular, the authors describe a linear time performance guaranteed approximation algorithm for the HP side chain model that constructs conformations whose energy is better than 865 of optimal in a face centered cubic lattice, and they demonstrate how this provides a 70% performance guarantee for the HP-TSSC model. This is the first algorithm in the literature for off-lattice protein structure prediction that has a rigorous performance guarantee. …

The generation of a stable colloidal suspension in geologic materials has a number of environmental implications. Mobile colloids may act as vectors for the transport of adsorbed contaminants through soils and within aquifers and can cause serious problems related to well monitoring and formation permeability in an injections well system. Colloid-facilitated transport has been implicated in the migration of contaminants from seepage basins on the Department of Energy`s Savannah River Site (SRS) at a rate greater than was predicted in two- phase transport models. From 1955 to 1988, seepage basins overlying the water-table aquifer received acidic wastes containing high levels of Na+ and nitric acid, as well as trace radionuclides and metals from the nuclear materials processing facilities. Numerical simulations predicted that metal contaminants would not reach the water table, but measurable quantities of these contaminants have been detected in monitoring wells down gradient from the basins. Lack of agreement between predicted and observed contaminant migration in this and other studies has been attributed to both local non equilibrium situation, preferential flow paths within the geologic material, and to transport of the contaminant in association with a mobile solid phase, i.e. dispersed colloids. Additionally, the association of contaminants with a …

During this quarterly period, the author has made progress in a number of areas. He has continued to evaluate potential candidates for high load/high speed antiwear action using the approach of generating tribopolymers capable of withstanding high temperatures. Results are promising for ceramics as well as steel. The construction of a new instrument for high temperature studies of both liquid and vapor phase lubrication is almost complete. This will permit studies up to 350 C bulk temperature and considerably higher surface temperatures in controlled vapor-phase and liquid-phase studies. Selected monomers and monomer combinations found to be effective in hexadecane as a carrier fluid have also been tested in other fluids, including synthetic ester lubricant carriers. Additional studies using FTIRM for surface analysis of wear tracks have been made and are continuing. Further industrial contacts have been made to arrange for field testing of selected compounds as antiwear additives. The applications include the lubrication of 2-stroke and 4-stroke engines, machining and cutting, and fuel injector wear, particularly in gas (e.g., natural gas) engines.
