Download or read book Cementitious Materials for Nuclear Waste Immobilization written by Rehab O. Abdel Rahman and published by John Wiley & Sons. This book was released on 2014-11-17 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cementitious materials are an essential part in any radioactive waste disposal facility. Conditioning processes such as cementation are used to convert waste into a stable solid form that is insoluble and will prevent dispersion to the surrounding environment. It is incredibly important to understand the long-term behavior of these materials. This book summarises approaches and current practices in use of cementitious materials for nuclear waste immobilisation. It gives a unique description of the most important aspects of cements as nuclear waste forms: starting with a description of wastes, analyzing the cementitious systems used for immobilization and describing the technologies used, and ending with analysis of cementitious waste forms and their long term behavior in an envisaged disposal environment. Extensive research has been devoted to study the feasibility of using cement or cement based materials in immobilizing and solidifying different radioactive wastes. However, these research results are scattered. This work provides the reader with both the science and technology of the immobilization process, and the cementitious materials used to immobilize nuclear waste. It summarizes current knowledge in the field, and highlights important areas that need more investigation. The chapters include: Introduction, Portland cement, Alternative cements, Cement characterization and testing, Radioactive waste cementation, Waste cementation technology, Cementitious wasteform durability and performance assessment.

Download or read book Immobolization of radioactive waste in ceramic based hosts Radioactive waste Immobolization written by Ashish Bohre and published by Anchor Academic Publishing (aap_verlag). This book was released on 2014-02-01 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ceramic materials have found numerous applications in science, technology and industry as mentioned earlier. One of the recent applications of titania and zirconia based ceramic precursors is in immobilization and solidification of radioactive isotopes in waste effluents coming out of nuclear establishments and power plants. Due to long term stability and integrity of the ceramic waste forms of high and intermediate level nuclear waste, several countries have now switched over from ‘glass technology’ to ‘ceramic technology’ of radwaste management. These and many more applications make ceramics materials an interesting area of research and engineering sciences. The book is particularly aimed at scientific and technical staff in the nuclear and waste management industries in addition to universities and research organizations active in these areas. It will also appeal to a wider audience with interests in environmental issues and will be of benefit to anyone who requires background information on radioactive issues connected with nuclear energy or defense processes, or hazardous waste sources, properties and treatments using crystallographic methods.

Download or read book Multifunctional Oxide Based Materials From Synthesis to Application written by Teofil Jesionowski and published by MDPI. This book was released on 2019-09-03 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with novel aspects and perspectives in metal oxide and hybrid material fabrication. The contributions are mainly focused on the search for a new group of advanced materials with designed physicochemical properties, especially an expanded porous structure and defined surface activity. The proposed technological procedures result in an enhanced activity of the synthesized hybrid materials, which is of great importance when considering their potential fields of application. The use of such materials in different technological disciplines, including aspects associated with environmental protection, allows for the verification of the proposed synthesis method. Thus, it can be stated that those aspects are of interdisciplinary character and may be located at the interface of three scientific disciplines—chemistry, materials science, and engineering—as well as environmental protection. Furthermore, the presented scientific scope is in some way an answer to the continuous demand for such types of materials and opens new perspectives for their practical use

Download or read book Ultra High Temperature Ceramics written by William G. Fahrenholtz and published by John Wiley & Sons. This book was released on 2014-10-10 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first comprehensive book to focus on ultra-high temperature ceramic materials in more than 20 years Ultra-High Temperature Ceramics are a family of compounds that display an unusual combination of properties, including extremely high melting temperatures (>3000°C), high hardness, and good chemical stability and strength at high temperatures. Typical UHTC materials are the carbides, nitrides, and borides of transition metals, but the Group IV compounds (Ti, Zr, Hf) plus TaC are generally considered to be the main focus of research due to the superior melting temperatures and stable high-melting temperature oxide that forms in situ. Rather than focusing on the latest scientific results, Ultra-High Temperature Ceramics: Materials for Extreme Environment Applications broadly and critically combines the historical aspects and the state-of-the-art on the processing, densification, properties, and performance of boride and carbide ceramics. In reviewing the historic studies and recent progress in the field, Ultra-High Temperature Ceramics: Materials for Extreme Environment Applications provides: Original reviews of research conducted in the 1960s and 70s Content on electronic structure, synthesis, powder processing, densification, property measurement, and characterization of boride and carbide ceramics. Emphasis on materials for hypersonic aerospace applications such as wing leading edges and propulsion components for vehicles traveling faster than Mach 5 Information on materials used in the extreme environments associated with high speed cutting tools and nuclear power generation Contributions are based on presentations by leading research groups at the conference "Ultra-High Temperature Ceramics: Materials for Extreme Environment Applications II" held May 13-19, 2012 in Hernstein, Austria.

Download or read book Immobilization of INEL Low level Radioactive Wastes in Ceramic Containment Materials written by W. C. Seymour and published by . This book was released on 1978 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: INEL low-level radioactive wastes have an overall chemical composition that lends itself to self-containment in a ceramic-based material. Fewer chemical additives would be needed to process the wastes than to process high-level wastes or use a mixture containment method. The resulting forms of waste material could include a basalt-type glass or glass ceramic and a ceramic-type brick. Expected leach resistance is discussed in relationshp to data found in the literature for these materials and appears encouraging. An overview of possible processing steps for the ceramic materials is presented.

Download or read book Glass and Ceramic Immobilization Alternatives and the Use of New Facilities written by and published by . This book was released on 1995 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Department of Energy (DOE) is examining options for placing weapons-usable surplus nuclear materials (principally plutonium [Pu] and highly enriched uranium [U]) in a form or condition that is substantially and inherently more difficult to use in weapons either by the Host Country or by a subnational group. The two most promising alternatives for achieving these aims are: fabrication and use as fuel, without reprocessing, in existing or modified nuclear reactors; or vitrification in combination with high-level radioactive waste. The mission of the immobilization technologies and facilities considered in this paper and the paper ''Use of Savannah River Site (SRS) Facilities for Glass and Ceramics, '' is to produce a waste form by incorporating plutonium in either an amorphous glass or a crystalline ceramic matrix and then disposal of it in a geologic repository. This paper summarizes all the glass and ceramic alternatives under consideration and presents the immobilization options using new facilities. The subsequent paper presents the immobilization options which use existing facilities at the Savannah River Site.
