A cold pump test, training, and mock-up facility needs to be acquired and installed to support Tank Waste Retrieval and Disposal (TWR&D). Such a facility would serve useful purposes for the TWR&D, and would also have the capability to provide similar services for other Hanford Site activities.

This document defines the functions and requirements (F&R) for a test facility to provide for pre-deployment, checkout, testing, and training for the underground storage tank retrieval equipment, systems, and crews that will be developed or deployed as part of Waste Feed Delivery. The F&R for a River Protection Project retrieval test facility, one that supports a production mode tank farm system, are identified.

The authors explore the use of variational grid-generation to perform alignment of a grid with a given vector field. Variational methods have proven to be a powerful class of grid-generators, but when they are used in alignment, difficulties may arise in treating boundaries due to an incompatibility between geometry and vector field. In this paper, a refinement of the procedure of iterating boundary values is presented. It allows one to control the quality of the grid in the face of the above-mentioned incompatibility. This procedure may be incorporated into any variational alignment algorithm. The authors demonstrate its use with respect to a new quasi-variational alignment method having a particularly simple structure. The latter method is comparable to Knupp's method (see [7]), but avoids use of the Winslow equations.

Scenarios for the building of muon colliders or storage rings suitable for the generation of robust neutrino beams call for the generation of a prodigious quantity of pions. These pions are then conducted into a decay channel where the resulting muon decay products can be collected for cooling and subsequent acceleration. Central to this concept is the design and construction of a target which will be highly efficient in producing pions of both signs while mitigating the absorption of these pions before they decay. This design effort is being facilitated by using two computer codes FLUKA and MARS. The authors present comparisons of the two computer codes and also present a comparison of these codes with available data.

Recent studies involving the use of micelles, reverse micelles, and microemulsions as organized microheterogeneous media for effecting photochemical transformations have led to growing recognition that the nature of the reaction medium (i.e., microenvironment) may strongly influence the course and efficiency of photoinduced electron transfer. Of particular interest in photochemical energy conversion research is the study of such effects in natural photosynthesis, the process whereby plants and photosynthetic bacteria convert light into chemical energy. The primary process in photosynthesis occurs in trasmembrane pigment-protein complexes called reaction centers (RCs), where following the absorption of light, primary charge separation occurs. This electrochemical energy is stored, and the initial charge separation used to drive all subsequent electron and proton transfer reactions in photosynthesis. One area of current research interest is the determination of the effect of conformational changes in detergent-solubilized RCs on electron transfer. In this report, the authors consider a related issue: the introduction of RCs into biomembrane mimetics and its impact on protein conformation, orientation, and function. As a medium for these studies, they have employed a recently developed stimulus-responsive complex fluid (smart material) that possesses the ability to respond to an environmental change/external stimulus on a molecular level and amplify it …

A regional groundwater flow model encompassing approximately 100 mi2 surrounding the C, K, L, and P reactor areas has been developed. The reactor flow model is designed to meet the planning objectives outlined in the General Groundwater Strategy for Reactor Area Projects by providing a common framework for analyzing groundwater flow, contaminant migration and remedial alternatives within the Reactor Projects team of the Environmental Restoration Department. The model provides a quantitative understanding of groundwater flow on a regional scale within the near surface aquifers and deeper semi-confined to confined aquifers. The model incorporates historical and current field characterization data up through Spring 1999. Model preprocessing is automated so that future updates and modifications can be performed quickly and efficiently. The CKLP regional reactor model can be used to guide characterization, perform scoping analyses of contaminant transport, and serve as a common base for subsequent finer-scale transport and remedial/feasibility models for each reactor area.

Sandia National Laboratory are working on ways to increase production using Knowledge Management. Knowledge Management is: finding ways to create, identify, capture, and distribute organizational knowledge to the people who need it; to help information and knowledge flow to the right people at the right time so they can act more efficiently and effectively; recognizing, documenting and distributing explicit knowledge (explicit knowledge is quantifiable and definable, it makes up reports, manuals, instructional materials, etc.) and tacit knowledge (tacit knowledge is doing and performing, it is a combination of experience, hunches, intuition, emotions, and beliefs) in order to improve organizational performance and a systematic approach to find, understand and use knowledge to create value.

An overall trend toward smaller electronic packages and devices makes it increasingly important and difficult to obtain meaningful diffraction information from small areas. X-ray micro-diffraction, electron back-scattered diffraction (EBSD) and Kossel are micro-diffraction techniques used for crystallographic analysis including texture, phase identification and strain measurements. X-ray micro-diffraction primarily is used for phase analysis and residual strain measurements. X-ray micro-diffraction primarily is used for phase analysis and residual strain measurements of areas between 10 {micro}m to 100 {micro}m. For areas this small glass capillary optics are used for producing a usable collimated x-ray beam. These optics are designed to reflect x-rays below the critical angle therefore allowing for larger solid acceptance angle at the x-ray source resulting in brighter smaller x-ray beams. The determination of residual strain using micro-diffraction techniques is very important to the semiconductor industry. Residual stresses have caused voiding of the interconnect metal which then destroys electrical continuity. Being able to determine the residual stress helps industry to predict failures from the aging effects of interconnects due to this stress voiding. Stress measurements would be impossible using a conventional x-ray diffractometer; however, utilizing a 30{micro}m glass capillary these small areas are readily assessable for analysis. Kossel produces a …

A non-invasive microwave device for the detection of epi/subdural hemorrhaging (hematoma) is under current development. The final device will be highly portable and allow real time assessment of head injuries, thereby satisfying early detection needs of the field technician as well as providing a tool for repetitious monitoring of high-risk individuals. The device will adopt the advanced technology of micropower impulse radar (MIR) which is a state of the art low cost ultra wide band (UWB) microwave radar developed here at LLNL. It will consist of a MIR transmitting and receiving module, a computer based signal processing module, and a device-to-patient signal coupling module--the UWB antenna. The prototype design is being guided by the needs of the patient and the practitioner along with the prerequisites of the technology including issues such as the specificity of the device, efficacy of diagnosis, accuracy, robustness, and patient comfort. The prototype development follows a concurrent approach which .includes experiments designed to evaluate requirements of the radar and antenna design, phantom development to facilitate laboratory investigations, and investigation into the limits of adapting pre-existing non-medical MIR devices to medical applications. This report will present the accomplishments and project highlights to date in the fiscal year …
