Cementitious Materials for Nuclear Waste Immobilization


Book Description

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.




Crystalline Materials for Actinide Immobilisation


Book Description

This book summarises approaches and current practices in actinide immobilisation using chemically-durable crystalline materials e.g. ceramics and monocrystals. Durable actinide-containing materials including crystalline ceramics and single crystals are attractive for various applications such as nuclear fuel to burn excess Pu, chemically inert sources of irradiation for use in unmanned space vehicles or producing electricity for microelectronic devices, and nuclear waste disposal. Long-lived -emitting actinides such as Pu, Np, Am and Cm are currently of serious concern has a result of increased worldwide growth in the nuclear industry. Actinide-bearing wastes have also accumulated in different countries as a result of nuclear weapons production. Excess weapon and civil Pu from commercial spent fuel is waiting for environmentally-safe immobilisation. As actinides are chemical elements with unique features, they could be beneficially used in different areas of human life including medicine although currently there is no appropriate balance between safe actinide disposal and use. Both use and disposal of actinides require their immobilisation in a durable host material. The choice of an optimal actinide immobilisation route is often a great challenge for specialists. There is a wealth of information about actinide properties in many publications although little is published to summarise the currently accepted approaches and practices on actinide immobilisation. This book intends to provide such information based on the authors' experience and studies in nuclear material management and actinide immobilisation.




Technical Approaches for the Management of Separated Civilian Plutonium


Book Description

This publication aims to outline credible technical options for managing separated plutonium. There is no attempt to rank or rate any of the options, instead the intent is to inform the reader of the technical merits of the various options and the state of their development. It is primarily focused on Member States that have adopted a closed fuel cycle policy but can also be of value to other Member States, specifically their decision makers and other stakeholders involved in potential future nuclear fuel cycles, by informing them on life cycle options and energy policy.







Ceramics for Environmental and Energy Applications


Book Description

This volume is a collection of 17 papers from six symposia held during the 8th Pacific Rim Conference on Ceramic and Glass Technology (PACRIM-8) in Vancouver, British Columbia, Canada, May 31-June 5, 2009. These symposia include: Glasses and Ceramics for Nuclear and Hazardous Waste Treatment Solid Oxide Fuel Cells and Hydrogen Technology Ceramics for Electric Energy Generation, Storage and Distribution Photocatalytic Materials: Reaction, Processing, and Applications Direct Thermal to Electrical Energy Conversion Materials and Applications PACRIM-8 is the eight in a series of international conferences on emerging ceramic technologies that began in 1993. PACRIM-8 was organized and sponsored by The American Ceramic Society and was endorsed by The Australian Ceramic Society, The Ceramic Society of Japan, The Chinese Ceramic Society, and The Korean Ceramic Society. A total of 862 experts, practitioners, and end users from forty-one countries attended PACRIM-8, making it one of the most successful ceramic science and engineering events in recent years.




Structural Chemistry of Inorganic Actinide Compounds


Book Description

Structural Chemistry of Inorganic Actinide Compounds is a collection of 13 reviews on structural and coordination chemistry of actinide compounds. Within the last decade, these compounds have attracted considerable attention because of their importance for radioactive waste management, catalysis, ion-exchange and absorption applications, etc. Synthetic and natural actinide compounds are also of great environmental concern as they form as a result of alteration of spent nuclear fuel and radioactive waste under Earth surface conditions, during burn-up of nuclear fuel in reactors, represent oxidation products of uranium miles and mine tailings, etc. The actinide compounds are also of considerable interest to material scientists due to the unique electronic properties of actinides that give rise to interesting physical properties controlled by the structural architecture of respective compounds. The book provides both general overview and review of recent developments in the field, including such emergent topics as nanomaterials and nanoparticles and their relevance to the transfer of actinides under environmental conditions.* Covers over 2,000 actinide compounds including materials, minerals and coordination polymers* Summarizes recent achievements in the field* Some chapters reveal (secret) advances made by the Soviet Union during the 'Cold war'




Nuclear Materials Safety Management Volume II


Book Description

LESLIE J. JARDINE Lmvrence Livermore National LaboratOlY Livermore, CA 94551 U. S. A. The Advanced Research Workshop (ARW) on Nuc1ear Materials Safety held lune 8-10, 1998, in St. Petersburg, Russia, was attended by 27 Russian experts from 14 different Russian organizations, seven European experts from six different organizations, and 14 V. S. experts from seven different organizations. The ARW was conducted at the State Education Center (SEC), a former Minatom nuc1ear training center in St. Petersburg. Thirty-three technical presentations were made using simultaneous translations. These presentations are reprinted in this volume as a formal ARW Proceedings in the NATO Science Series. The representative technical papers contained here cover nuc1ear material safety topics on the storage and disposition of excess plutonium and high enriched uranium (HEU) fissile materials, inc1uding vitrification, mixed oxide (MOX) fuel fabrication, plutonium ceramics, reprocessing, geologic disposal, transportation, and Russian regulatory processes. This AR W completed discussions by experts of the nuc1ear materials safety topics that were not covered in the previous, companion ARW on Nuc1ear Materials Safety held in Amarillo, Texas, in March 1997. These two workshops, when viewed together as a set, have addressed most nuc1ear material aspects of the storage and disposition operations required for excess HEV and plutonium (see Fig. 1, Opening Remarks).
