This publication will assist Member States with the formation and implementation of efficient strategies for safe and cost effective classification and disposal of nuclear wastes. By exploiting the benefits of the scaling factor (SF) method of waste characterization, waste management professionals can facilitate the processing of larger quantities of heterogeneous radioactive waste. Whereas before, the complexity of quantifying difficult-to-measure (DTM) nuclides within sealed waste packages frustrated the efficient management of their disposal, the new SF methodology exploits known quantifiable ratios of DTM to easy-to-measure (ETM) nuclides so as to facilitate radioactive waste processing. This publication contains guidance and case studies from Member States where the technique has been successfully deployed, and provides an essential and effective complement to the recently published ISO standard 21238:2007 on the same topic.

Over the past decade significant progress has been achieved in the development of waste characterization and control procedures and equipment as a direct response to ever-increasing requirements for quality and reliability of information on waste characteristics. Failure in control procedures at any step can have important, adverse consequences and may result in producing waste packages which are not compliant with the waste acceptance criteria for disposal, thereby adversely impacting the repository. The information and guidance included in this publication corresponds to recent achievements and reflects the optimum approaches, thereby reducing the potential for error and enhancing the quality of the end product. -- Publisher's description.

Disposal of radioactive waste from nuclear weapons production and power generation has caused public outcry and political consternation. Nuclear Wastes presents a critical review of some waste management and disposal alternatives to the current national policy of direct disposal of light water reactor spent fuel. The book offers clearcut conclusions for what the nation should do today and what solutions should be explored for tomorrow. The committee examines the currently used "once-through" fuel cycle versus different alternatives of separations and transmutation technology systems, by which hazardous radionuclides are converted to nuclides that are either stable or radioactive with short half-lives. The volume provides detailed findings and conclusions about the status and feasibility of plutonium extraction and more advanced separations technologies, as well as three principal transmutation concepts for commercial reactor spent fuel. The book discusses nuclear proliferation; the U.S. nuclear regulatory structure; issues of health, safety and transportation; the proposed sale of electrical energy as a means of paying for the transmutation system; and other key issues.

This report describes and assesses radiological characterization as a precursor to decommissioning. It shows the influence of the radioactive inventory on the planning and strategies of decommissioning and also presents an extensive overview of characterization results on various reactors which have been or are being decommissioned.

This book covers various topics, from thermal-hydraulic analysis to the safety analysis of nuclear power plant. It does not focus only on current power plant issues. Instead, it aims to address the challenging ideas that can be implemented in and used for the development of future nuclear power plants. This book will take the readers into the world of innovative research and development of future plants. Find your interests inside this book!

Drawing on the authors' extensive experience in the processing and disposal of waste, An Introduction to Nuclear Waste Immobilisation, Second Edition examines the gamut of nuclear waste issues from the natural level of radionuclides in the environment to geological disposal of waste-forms and their long-term behavior. It covers all-important aspects of processing and immobilization, including nuclear decay, regulations, new technologies and methods. Significant focus is given to the analysis of the various matrices used, especially cement and glass, with further discussion of other matrices such as bitumen. The final chapter concentrates on the performance assessment of immobilizing materials and safety of disposal, providing a full range of the resources needed to understand and correctly immobilize nuclear waste. - The fully revised second edition focuses on core technologies and has an integrated approach to immobilization and hazards - Each chapter focuses on a different matrix used in nuclear waste immobilization: cement, bitumen, glass and new materials - Keeps the most important issues surrounding nuclear waste - such as treatment schemes and technologies and disposal - at the forefront

Providing recommendations on the application of the concept of clearance for materials, objects and buildings that are to be released from regulatory control, this publication supports the application of the relevant requirements of IAEA Safety Standards Series No. GSR Part 3. It includes detail on the regulatory framework for clearance; the clearance process; the derivation of clearance levels; the application of clearance to solid materials, liquids and gases; generic clearance and specific clearance using activity concentration and surface contamination clearance levels. It also provides recommendations on the involvement of interested parties. Written for governmental officials, and those working for regulatory bodies and operating organizations, this publication will also be of interest to technical service providers in radiation protection. The recommendations provided are applicable to facilities that use, manufacture, process or store radioactive material, such as nuclear power plants, research reactors, other nuclear fuel cycle facilities, facilities for the management of radioactive waste, industrial plants, medical facilities, research facilities, educational facilities and accelerators. The recommendations in this publication also apply to industries processing materials containing radionuclides of natural origin and to the management of material originating from remediation activities or from post- emergency situations.

Provides detailed information on the handling, processing and storage techniques most widely used and recommended for waste from non-fuel-cycle activities. The report was designed to meet the needs of developing countries by focusing on the most simple, affordable and reliable techniques and discussing their advantages and limitations.

This report provides information and discussion on planning, methodologies and technologies for retrieval and reconditioning of radioactive wastes recovered from old, inadequate disposal or storage facilities. The objective of such projects is to improve waste safety and security in accordance with modern requirements. Selected international experiences in waste retrieval and recovery projects are included. The report serves as a guide for storage and disposal facility personnel responsible for the organization and implementation of waste retrieval and reconditioning projects to optimize planning, selection and use of available and applicable technologies and resources.--Publisher's description.
