Available in PDF, EPUB and Kindle. Book excerpt: Yucca Mountain Site Characterization Project (YMP) is studying Yucca Mountain, Nevada as a potential repository for high-level nuclear wastes. The studies include predictions of the quantity and composition of water in the repository near-field environment that will affect the release rate of radioactive nuclides from waste packages, and the transport of the nuclides through the rock mass adjacent to these packages. The radioactive decay heat from the high- level nuclear waste may increase the temperature in the rock mass to the extent that coupled thermal-mechanical-hydrological-chemical (TMHC) processes may exist in the originally -partially-saturated Topopah Spring tuff-the host rock for the potential repository in Yucca Mountain. Modeling the coupled TMHC processes is necessary to predict the quantity and quality of water in the near-field environment for the entire life span of a repository (tens of thousands of years). In situ thermal tests are required to build up the confidence level of the coupled TMHC models. The purposes of conducting the laboratory studies of the coupled TMHC processes are to enhance our understanding of those processes, and to assist the interpretation of the field test results. Laboratory experiments deal with controlled experimental and boundary conditions, smaller sample sizes, and simpler geometrical configurations (e.g., regular shape and single fracture). These characteristics make the laboratory results suitable for understanding the processes. This in turn will make incorporation of these processes in model calculations more manageable. However, it should be noted that small sample size and simple geometrical configuration make the results of the laboratory tests unsuitable for direct use in predicting behaviors of in situ rock mass. The laboratory tests included in this reporting period are summarized below, along with projection of future work. This report fulfills the level 4 Milestone ID: SPL7A5M4.

Book excerpt: The main purpose of this report is to document observations and data on thermally coupled processes for conditions that are expected to occur within and around a repository at Yucca Mountain. Some attempt is made to summarize values of properties (e.g., thermal properties, hydrologic properties) that can be measured in the laboratory on intact samples of the rock matrix. Variation of these properties with temperature, or with conditions likely to be encountered at elevated temperature in the host rock, is of particular interest. However, the main emphasis of this report is on direct observation of thermally coupled processes at various scales. Direct phenomenological observations are vitally important in developing and testing conceptual models. If the mathematical implementation of a conceptual model predicts a consequence that is not observed, either (1) the parameters or the boundary conditions used in the calculation are incorrect or (2) the conceptual basis of the model does not fit the experiment; in either case, the model must be revised. For example, the effective continuum model that has been used in thermohydrology studies combines matrix and fracture flow in a way that is equivalent to an assumption that water is imbibed instantaneously from fractures into adjacent, partially saturated matrix. Based on this approximation, the continuum-flow response that is analogous to fracture flow will not occur until the effective continuum is almost completely saturated. This approximation is not entirely consistent with some of the experimental data presented in this report. This report documents laboratory work and field studies undertaken in FY96 and FY97 to investigate thermally coupled processes such as heat pipes and fracture-matrix coupling. In addition, relevant activities from past years, and work undertaken outside the Yucca Mountain project are summarized and discussed. Natural and artificial analogs are also discussed to provide a convenient source of material documenting the conceptual and mathematical basis for modeling coupled phenomena. The actual models and codes, and their specific empirical and theoretical bases, will be documented in a separate report to be delivered in FY99.

A limited number of projects sponsored by international organizations such as the International Atomic Energy Agency are also included. This directory consists of nine chapters and opens with a section on organic sources of energy such as coal, oil and gas, peat, hydrocarbons, and non-fossil organic sources. The next sections focus on thermonuclear energy and plasma physics; fission sources and energy production; geophysical energy sources; conversion technology; and environmental aspects of energy conversion and use. Energy transport, transmission, utilization, and conservation are also covered. The final chapter deals with energy systems and other energy-related research on subjects ranging from car sharing and urban passenger transport to nuclear power plants, energy supply and demand models, and high-power molecular lasers. This monograph will be a valuable resource of information for those involved in energy research and development.

Book excerpt: Advances in Engineering Materials, Structures and Systems: Innovations, Mechanics and Applications comprises 411 papers that were presented at SEMC 2019, the Seventh International Conference on Structural Engineering, Mechanics and Computation, held in Cape Town, South Africa, from 2 to 4 September 2019. The subject matter reflects the broad scope of SEMC conferences, and covers a wide variety of engineering materials (both traditional and innovative) and many types of structures. The many topics featured in these Proceedings can be classified into six broad categories that deal with: (i) the mechanics of materials and fluids (elasticity, plasticity, flow through porous media, fluid dynamics, fracture, fatigue, damage, delamination, corrosion, bond, creep, shrinkage, etc); (ii) the mechanics of structures and systems (structural dynamics, vibration, seismic response, soil-structure interaction, fluid-structure interaction, response to blast and impact, response to fire, structural stability, buckling, collapse behaviour); (iii) the numerical modelling and experimental testing of materials and structures (numerical methods, simulation techniques, multi-scale modelling, computational modelling, laboratory testing, field testing, experimental measurements); (iv) innovations and special structures (nanostructures, adaptive structures, smart structures, composite structures, bio-inspired structures, shell structures, membranes, space structures, lightweight structures, long-span structures, tall buildings, wind turbines, etc); (v) design in traditional engineering materials (steel, concrete, steel-concrete composite, aluminium, masonry, timber, glass); (vi) the process of structural engineering (conceptualisation, planning, analysis, design, optimization, construction, assembly, manufacture, testing, maintenance, monitoring, assessment, repair, strengthening, retrofitting, decommissioning). The SEMC 2019 Proceedings will be of interest to civil, structural, mechanical, marine and aerospace engineers. Researchers, developers, practitioners and academics in these disciplines will find them useful. Two versions of the papers are available. Short versions, intended to be concise but self-contained summaries of the full papers, are in this printed book. The full versions of the papers are in the e-book.
