Disposition of High-Level Waste and Spent Nuclear Fuel


Book Description

Focused attention by world leaders is needed to address the substantial challenges posed by disposal of spent nuclear fuel from reactors and high-level radioactive waste from processing such fuel. The biggest challenges in achieving safe and secure storage and permanent waste disposal are societal, although technical challenges remain. Disposition of radioactive wastes in a deep geological repository is a sound approach as long as it progresses through a stepwise decision-making process that takes advantage of technical advances, public participation, and international cooperation. Written for concerned citizens as well as policymakers, this book was sponsored by the U.S. Department of Energy, U.S. Nuclear Regulatory Commission, and waste management organizations in eight other countries.

Nuclear Back-end and Transmutation Technology for Waste Disposal


Book Description

This book covers essential aspects of transmutation technologies, highlighting especially the advances in Japan. The accident at the Fukushima Daiichi Nuclear Power Plant (NPP) has caused us to focus attention on a large amount of spent nuclear fuels stored in NPPs. In addition, public anxiety regarding the treatment and disposal of high-level radioactive wastes that require long-term control is growing. The Japanese policy on the back-end of the nuclear fuel cycle is still unpredictable in the aftermath of the accident. Therefore, research and development for enhancing the safety of various processes involved in nuclear energy production are being actively pursued worldwide. In particular, nuclear transmutation technology has been drawing significant attention after the accident. This publication is timely with the following highlights: 1) Development of accelerator-driven systems (ADSs), which is a brand-new reactor concept for transmutation of highly radioactive wastes; 2) Nuclear reactor systems from the point of view of the nuclear fuel cycle. How to reduce nuclear wastes or how to treat them including the debris from TEPCO’s Fukushima nuclear power stations is discussed; and 3) Environmental radioactivity, radioactive waste treatment and geological disposal policy. State-of-the-art technologies for overall back-end issues of the nuclear fuel cycle as well as the technologies of transmutation are presented here. The chapter authors are actively involved in the development of ADSs and transmutation-related technologies. The future of the back-end issues in Japan is very uncertain after the accident at the Fukushima Daiichi NPP and this book provides an opportunity for readers to consider the future direction of those issues.




Managing Radioactive Waste Safely


Book Description

Published as part of the managing radioactive waste safely (MRWS) programme, this white paper sets out the UK Government's framework for managing higher activity radioactive waste in the long-term through geological disposal, coupled with safe and secure interim storage and ongoing research and development to support its optimised implementation. It also invites communities to express an interest in opening up, without commitment, discussions with Government on the possibility of hosting a geological disposal facility at some point in the future. In June 2007 the Government published a MRWS consultation document in conjunction with the devolved administrations for Wales and Northern Ireland. Responses to this consultation have been taken into consideration in the development of this white paper. The paper sets out the framework for the future implementation of geological disposal that includes: the approach to compiling and updating the UK Radioactive Waste Inventory (UKRWI) and using it as a basis for discussion with potential host communities; the Nuclear Decommissioning Authority's technical approach for developing a geological disposal facility, including the use of a staged implementation approach and ongoing research and development to support delivery. The white paper covers the amount of waste for disposal; preparation and planning for geological disposal; protecting people and the environment: regulation, planning and independent scrutiny; site selection using a voluntarism and partnership approach; the site assessment process; timing and next steps.




Costing Methods and Funding Schemes for Radioactive Waste Disposal Programmes


Book Description

Reliable methods for estimating the cost of a radioactive waste disposal programme are crucial to ensure that the necessary funding for completing the disposal programme is available. Estimating the cost for disposal is, however, a challenging and complex task. Disposal programmes themselves are complex and long term undertakings, and conditions can be expected to change significantly over the time span during which a disposal programme is developed and implemented. This publication provides Member States with information on developing cost estimates for a disposal programme and establishing funding mechanisms. It will help readers in becoming informed clients by familiarizing themselves with the approaches and complexities in cost estimates and funding mechanisms for disposal. The publication is applicable to all waste categories and both near surface and geological disposal. It contains relevant examples and case studies from national programmes. The cost figures are intended to give an indication of the possible cost of certain parts or aspects of the disposal programme rather than to compare different disposal programmes’ costs.




Low-level Radioactive Waste Repositories


Book Description

This report sets out the costs of operating disposal sites for LLW in OECD countries, as well as the factors that may affect the costs of sites being developed.




Meeting the energy challenge


Book Description

The May 2007 White Paper "Meeting the energy challenge: a white paper on energy" (Cm. 7124, ISBN 9780101712422) set out the Government's international and domestic strategy to address the two main challenges: tackling climate change by reducing carbon dioxide emissions; and ensuring clean and affordable energy as the country becomes increasingly dependent on imported fuel. An online consultation on nuclear power and the role of the private sector: www.direct.gov.uk/nuclearpower2007 was produced at the same time. This White Paper sets out the Government's decision taken in response to the consultation. The Government believes it is in the public interest that new nuclear power stations should have a role to play in the country's future energy mix alongside other low-carbon sources; that energy companies should have the option of investing in them; and that the Government should take active steps to open up the way to the construction of new nuclear power stations. It will be for the energy companies to fund, develop and build the new stations, including meeting the full costs of decommissioning and their full share of waste management costs. Section 1 summarises the consultation process. Section 2 addresses the key issues that arose from the consultation and how they have been taken into account in shaping policy and reaching conclusions. Section 3 outlines the facilitative actions the Government will take to reduce the regulatory and planning risks associated with investing in new nuclear power stations. Finally there are three annexes: alternatives to nuclear power; justification and strategic siting assessment processes; regulatory and advisory structure for nuclear power.




An Introduction to Nuclear Waste Immobilisation


Book Description

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.




Strategy and Methodology for Radioactive Waste Characterization


Book Description

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.
