The main outcomes of RILEM TC-226-CNM are summarized in this book. Key input was provided by researchers from countries that are main contributors in the R&D, design, construction, operation, and regulation of waste nuclear reinforced concrete facilities. Nuclear power plants and many of the facilities and structures used for the management of radioactive waste materials generated by the fuel cycle use concrete in their construction. RILEM TC 226 CNM covered several areas including functional and performance requirements for concrete structures; degradation processes; phenomenological modelling, field experiences, tests approaches, instrumentation and monitoring methods dedicated to performance assessments; service-life models; aging Management of Nuclear Power Plants, repair techniques; codes and standards specific to radioactive waste facilities.

Sustainability of Life Cycle Management for Nuclear Cementation-Based Technologies, edited by Dr. Rahman and Dr. Ojovan, presents the latest knowledge and research on the management of cementitious systems within nuclear power plants. The book covers aging, development and updates on regulatory frameworks on a global scale, the development of cementitious systems for the immobilization of problematic wastes, and the decommissioning and decontamination of complex cementitious systems. The book's editors and their team of experts combine their practical knowledge to provide the reader with a thorough understanding on the sustainability of lifecycle management of cementitious systems within the nuclear industry. Sections provide a comparative tool that presents national regulations concerning cementitious systems within nuclear power plants, check international and national evaluation results of the sustainability of different systems, help in the development of performance test procedures, and provide a guide on aging nuclear power plants and the long-term behavior of these systems in active and passive safety environments. - Presents the latest information on the behavior of different cementitious systems used in the nuclear industry in one comprehensive resource - Includes scientific justifications of system behavior during the design, operation, maintenance and decommissioning phases - Aids the reader in the development of evaluation tests for problematic wastes

Concrete technology for a sustainable development in the 21st century focuses on the problems and challenges for the concrete industry today and in the future with particular emphasis on environmental consiousness. Primary topics include: the improvement of concretes service life to ease technical and economical problems and the waste of natural re

The International Conference on Waste Management and the Environment is organised every two years by the Wessex Institute of Technology in collaboration with other institutions. This fifth conference follows the success of previous meetings held in C diz (2002), Rhodes (2004), Malta (2006) and Granada (2008). Waste Management is becoming one of the key problems of the modern world, an international issue that is intensified by the volume and complexity of domestic and industrial waste discarded by society. Unfortunately, many of the practices adopted in the past were aimed at short-term solutions without sufficient regard or knowledge for long-term implications on health, the environment or sustainability and this, in many cases, is leading to the need to take difficult and expensive remedial action. With our growing awareness of the detrimental environmental effects of current waste disposal, there is a significant onus of accountability for effective waste management. Better practice and safer solutions are required. Not only is there a need for more research on current disposal methods such as landfill, incineration, chemical and effluent treatment, but also on recycling, waste minimisation, clean technologies, waste monitoring, public and corporate awareness, and general education.

President Carter's 1980 declaration of a state of emergency at Love Canal, New York, recognized that residents' health had been affected by nearby chemical waste sites. The Resource Conservation and Recovery Act, enacted in 1976, ushered in a new era of waste management disposal designed to protect the public from harm. It required that modern waste containment systems use "engineered" barriers designed to isolate hazardous and toxic wastes and prevent them from seeping into the environment. These containment systems are now employed at thousands of waste sites around the United States, and their effectiveness must be continually monitored. Assessment of the Performance of Engineered Waste Containment Barriers assesses the performance of waste containment barriers to date. Existing data suggest that waste containment systems with liners and covers, when constructed and maintained in accordance with current regulations, are performing well thus far. However, they have not been in existence long enough to assess long-term (postclosure) performance, which may extend for hundreds of years. The book makes recommendations on how to improve future assessments and increase confidence in predictions of barrier system performance which will be of interest to policy makers, environmental interest groups, industrial waste producers, and industrial waste management industry.
