Summary of GAO's Findings on the Safety and Efficacy of the Anthrax Vaccine
Correspondence issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO reviewed the Department of Defense's (DOD) anthrax immunization program, focusing on the: (1) need for a six-shot regimen and annual booster shots; (2) long- and short-term safety of the vaccine; (3) efficacy of the vaccine; and (4) extent to which problems the Food and Drug Administration (FDA) found in the vaccine production facility in Michigan could compromise the safety, efficacy, and quality of the vaccine."

Uranium (VI) and Neptunium (V) Transport Fractured, Hydrothermally Altered Concrete
In a high level waste repository in which temperatures are elevated due to waste decay, concrete structures will be subjected to hydrothermal conditions that will alter their physical and chemical properties. Virtually no studies have examined the interaction of hydrothermally altered concrete with radionuclides. We present the results of experiments in which soluble and colloid-associated actinides, uranium (U) and neptunium (Np), were eluted into a fractured, hydrothermally altered concrete core. Although the fluid residence time in the fracture was estimated to be on the order of 1 minute, U and Np were below detection (10{sup -9}-10{sup -8} M) in the effluent from the core, for both soluble and colloid-associated species. Inorganic colloids and latex microspheres were similarly immobilized within the core. Post-test analysis of the core identified the immobilized U and Np at or near the fracture surface, with a spatial distribution similar to that of the latex microspheres. Because hydrothermal alteration followed fracturing, the growth of crystalline calcium silicate hydrate and clay mineral alteration products on, and possibly across the fracture, resulted in a highly reactive fracture that was effective at capturing both soluble and colloidal radionuclides. Comparison of results from batch experiments [1] with these experiments indicate that …

Use of Morphological Operators and Pattern Recognition Techniques for Sorting the First Data
The application of morphological and pattern recognition techniques to the sorting of FIRST data is presented. FIRST (Faint Images of the Radio Sky at Twenty Centimeters) is designed to produce the radio equivalent of the Palomar Observatory Sky Survey, using the National Radio Astronomical Observatory Very Large Array. A catalog of source positions and Gaussian-fit parameters for the sources is available. The goal of this part of the project is the automatic classification of types of sources, since it is expected that there will be on the order of one million sources in the final catalog. The data consists of radio maps, each approximately 1500 x 1100 pixels and containing on average about 30 sources per map. The resolution of these maps is 5 inches (approximately 3 pixels). The sources range in size from a few pixels to 70 or 80 pixels maximum diameter and have various morphologies. Of particular interest is the extraction of ''bent doubles'', core-jets, and gravitational lens candidates. These interesting types constitute on the order of one percent of the sources. The emphasis in this presentation is on image-based pattern recognition. We report on the use of morphological operators for source extraction and compare use of …

Ventilation Model
The purpose of this analysis and model report (AMR) for the Ventilation Model is to analyze the effects of pre-closure continuous ventilation in the Engineered Barrier System (EBS) emplacement drifts and provide heat removal data to support EBS design. It will also provide input data (initial conditions, and time varying boundary conditions) for the EBS post-closure performance assessment and the EBS Water Distribution and Removal Process Model. The objective of the analysis is to develop, describe, and apply calculation methods and models that can be used to predict thermal conditions within emplacement drifts under forced ventilation during the pre-closure period. The scope of this analysis includes: (1) Provide a general description of effects and heat transfer process of emplacement drift ventilation. (2) Develop a modeling approach to simulate the impacts of pre-closure ventilation on the thermal conditions in emplacement drifts. (3) Identify and document inputs to be used for modeling emplacement ventilation. (4) Perform calculations of temperatures and heat removal in the emplacement drift. (5) Address general considerations of the effect of water/moisture removal by ventilation on the repository thermal conditions. The numerical modeling in this document will be limited to heat-only modeling and calculations. Only a preliminary assessment of …

Investigation of groundwater flow paths through combined inversion of strontium isotope ratios and hydraulic head data. Final report
Strontium (Sr) isotope and other geochemical data were collected for groundwater samples from the Snake River Plain aquifer in the vicinity of the Idaho National Engineering and Environmental Laboratory (INEEL). These geochemical data provide strong evidence for slow and fast groundwater flow zones that had not been previously characterized. The geochemical data were combined with existing hydraulic head data in groundwater flow and transport models. These models enable quantitative extraction of flow information from the data (i.e., inversion of the data). This new approach and the implications for INEEL environmental activities will be reported in two journal articles. One submitted recently and a second in preparation.
