T his report summarizes the core research, development, and technology accomplishments in Lawrence Livermore National Laboratory's Engineering Directorate for FY2006. These efforts exemplify Engineering's more than 50-year history of developing and applying the technologies needed to support the Laboratory's national security missions. A partner in every major program and project at the Laboratory throughout its existence, Engineering has prepared for this role with a skilled workforce and technical resources developed through both internal and external venues. These accomplishments embody Engineering's mission: "Enable program success today and ensure the Laboratory's vitality tomorrow."Engineering's investment in technologies is carried out primarily through two internal programs: the Laboratory Directed Research and Development (LDRD) program and the technology base, or "Tech Base," program. LDRD is the vehicle for creating technologies and competencies that are cutting-edge, or require discovery-class research to be fully understood. Tech Base is used to prepare those technologies to be more broadly applicable to a variety of Laboratory needs. The term commonly used for Tech Base projects is "reduction to practice." Thus, LDRD reports have a strong research emphasis, while Tech Base reports document discipline-oriented, core competency activities.This report combines the LDRD and Tech Base summaries into one volume, organized into six thematic technical areas: Engineering Modeling and Simulation; Measurement Technologies; Micro/ Nano-Devices and Structures; Precision Engineering; Engineering Systems for Knowledge and Inference; and Energy Manipulation.Engineering Modeling and Simulation efforts focus on the research, development, and deployment of computational technologies that provide the foundational capabilities to address most facets of Engineering's mission. Current activities range from fundamental advances to enable accurate modeling of full-scale DOE and DoD systems performing at their limits, to advances for treating photonic and microfl uidic systems.FY2006 LDRD projects encompassed coupling standard fi nite element analysis methods with "meshless" methods to address systems at and beyond failure; integration of electromagnetic forces with structural mechanics solutions; and nonlinear materials treatments for photonic systems. Tech Base projects included enhancements, verifi cation, and validation of engineering simulation tools and capabilities; progress in visualization and data management tools; and extensions of our competence in structural damage analysis.Measurement Technologies comprise activities in nondestructive characterization, metrology, sensors systems, and ultrafast technologies for advanced diagnostics. The advances in this area are essential for the future experimental needs in Inertial Confi nement Fusion, High-Energy-Density Physics, Weapons and Department of Homeland Security programs.FY2006 LDRD research featured transient recording extensions for streak cameras; investigations...

The Center for Computational Engineering orchestrates the research, development, and deployment of software technologies to aid in many facets of the Laboratory's engineering mission. Computational engineering has become a ubiquitous component throughout the engineering discipline. Current activities range from tools to design the next generation of mixed-signal chips (systems on a chip) to full-scale analysis of key DOE and DoD systems.Highlights of the Center's LDRD projects for this year include advances in finite-element methods, and modeling and simulation tools; hypersonic flow; modeling and characterization of recompressed damaged materials; and propagation models for communication system performance. The Center has offered a real-world computing capability that opens the door to solving a wide variety of fluid/solid interaction problems in transportation, aerospace, and infrastructure settings.The mission of the Center for Microtechnology and Nanotechnology is to invent, develop, and apply microscale and nanoscale technologies to support the Laboratory missions in Stockpile Stewardship, Homeland Security, Nonproliferation, and other programs. The research topics for this Center cover materials, devices, instruments, and systems that require microfabricated components, including microelectromechanical systems (MEMS), electronics, photonics, micro-and nanostructures, and micro-and nanoactuators.This year's projects include analysis and optimization of sample systems; integrated microfluidic fuel processor; microfluidic system for bioassay; modeling tools for photonic ICs; nanoscale fabrication of mesoscale objects; disposable PCR device; and optical code-division multiple access for fiber-optic networks.The Center for Nondestructive Characterization (NDC) researches and develops nondestructive characterization measurement technology to significantly impact the manner in which the Laboratory inspects, and through this, designs, fabricates, and refurbishes systems and components. The Center plays a strategic and vital role in the research and development of scientific and engineering NDC technologies, such as acoustic, infrared, microwave, visible and x-ray imaging, to enable Engineering in the far-to mid-term to incorporate the successful technologies into Laboratory and DOE programs.This year's LDRD projects include concealed threat detection at multiple frames/s; high-accuracy x-ray imaging of mesoscale targets; radial reflection diffraction tomography; tabletop mesoscale NDC; and ultrasonic NDE of multilayered structures.The Center for Precision Engineering advances the Laboratory's high-precision capabilities in manufacturing, dimensional metrology and assembly, to meet the future needs of the Laboratory and DOE programs. Precision engineering is a multi-disciplinary systems approach to achieve

The Study was conducted using a systems analysis approach which consi dered the various situations which could lead to potential releases of radioactive materials during the handling, sturage, transportation, and disposal of high-level solid wastes (HLSW). A systems analysis approach was chosen to facilitate the identification of potential release points and mechanisms which would be limiting in establishing criteria, i.e., to identify potential points of release in the management cycle most sensitive to the waste form characteristics.-3- Development of criteria for the safe disposal of nuclear wastes in geologic media requires the establishment of definitive objectives ayainst which the adequacy of various waste management methods may be judged. This report suyyests certain guidelines that might serve as first approximations pending this issuing of official criteria. These include:• The allowable radiation dose to individuals should be related to the predicted probability of receiviny the dose such that as the dose increases, the events leadiny to that dose should become less probable. A quantitative relationship is developed and discussed.. Selection of a waste management method should be made in accordance with the principles of ALARA.« Doses to future generations should be considerea to be equally as serious as doses to present populations.• When the hazard potential of an underground nuclear waste repository becomes less than that of typicai hazardous ore formations (i.e., U.2% uranium ore), further concern is unwarranted.-a- This handbook contains reference information on parameters that should be considered in analyzing or modeling a proposed nuclear waste reposi tory. Only those parameters and values that best represent the natural environmental are considered. We avoid rare extremes. Where laboratory and field data are inadequate, we rely on theoretical treatments and informed engineering judgments.The handbook is divided into seven chapters: 1) Geomechanics of Bedded Salt, 2) Hydrology, 3) Geochemistry, 4) Seismology, 5) Geology of Bedded and Dome Salt, 6) Natural Features, and 7) Man-Hade Features.
