Integrated performance assessments (IPAs) of radioactive waste repositories deep underground are made at different stages of repository development in order, for example, to allow full-scale development, to provide feedback to R&D, and to test and develop review capability. IPA studies must be acceptable to a wide range of stakeholders and are one of the bases for dialogue amongst regulators and implementers of disposal facilities. The goal of the IPAG-2 study was to examine the experience of regulatory reviews of IPAs, from both the implementer and regulator points of view. Ten implementer and seven regulatory organisations participated. This report presents the lessons learnt from their review experiences, and provides recommendations to aid future regulatory decision making.

Analysis of the long-term safety of radioactive waste repositories, using performance assessment and other tools, is required prior to implementation. The initial stage in developing a repository safety assessment is the identification of all factors that may be relevant to the long-term safety of the repository and their combination to form scenarios. This must be done in a systematic and transparent way in order to assure the regulatory authorities that nothing important has been forgotten. This report is a review of developments in scenario methodologies based on a large body of practical experience in safety assessments. It will be of interest to radioactive waste management experts as well as to other specialists involved in the development of scenario methodologies.

Confidence among both technical experts and the public in the safety of deep geologic repositories for radioactive waste is a key element in the successful development of the repositories. This report presents the approaches and arguments that are currently used in OECD countries to establish and communicate confidence in their safety. It evaluates the state of the art for obtaining, presenting and demonstrating confidence in long-term safety, and makes recommendations on future directions and initiatives to be taken for improving confidence.

A general consensus has been reached among technical experts that high-level radioactive waste can safely be disposed of in deep geological repositories. Safety studies are carried out to evaluate the overall capacity of a particular disposal site to confine waste and minimise radioactive releases. Since the principal way in which radioactive elements might eventually reach the biosphere is by transport of dissolved radionuclides in groundwater, the safety study calculations must be able to estimate their rate of transfer through each of the barriers surrounding the repository. It is well known that, for many radioelements, sorption reactions can lead to a reduction of the amount of radionuclides present in the solution phase. How best to take radionuclide sorption reactions into account in repository performance assessment models is the subject of this book.

One of the challenges facing the continued availability of nuclear energy is that of ensuring the safe, environmentally acceptable and economic management of the waste generated during its production. There is a broad scientific and technical consensus that disposal of high-level, long-lived radioactive waste in deep geologic formations is an appropriate and safe means of isolating it from the biosphere for very long time scales. There have, however, been setbacks in the disposal programmes in many countries, primarily due to the failure of the waste management community to win sufficient public and political support. This report, which is based on recent work of the OECD Nuclear Energy Agency (NEA), reviews the progress to date in this field and the further steps that may be required to implement geologic disposal, taking into account both the technical and regulatory requirements, and the need to achieve an appropriate level of societal acceptance.This book should be of interest to government and industry decision makers, academics and all those eager to better understand what is at stake in this widely debated subject and the prospects that emerge.
