Book Description
A key challenge in the development of safety cases for the deep geological disposal of radioactive waste is handling the long time frame over which the radioactive waste remains hazardous. The intrinsic hazard of the waste decreases with time, but some hazard remains for extremely long periods. This report reviews the current status and ongoing discussions of this issue, addressing such issues as ethical principles, the evolution of the hazard over time, uncertainties in the evolution of the disposal system (and how these uncertainties themselves evolve), the stability and predictability of the geological environment, repository planning and implementation including regulatory requirements, siting decisions, repository design, the development and presentation of safety cases and the planning of pre- and post-closure institutional controls such as monitoring requirements.

Book Description
Deep geological repositories are sited and designed to protect humans and the environment from the hazards associated with radioactive waste. A repository safety case needs to address the period fro which it is possible to contain the radioactivity. Furthermore, safety is usually assessed in terms of the primary indicators of dose and risk and, in order to evaluate these indicators, assumptions must be regarding rhe habits of potentially exposed groups (e.g. diet, lifestyle and land use) and these may change over timescales of just a few years. The need to deal with such a wide range fo timescales gives rise to a range of issues regarding the methods and presentation of safety assessements. The main objective of the workshop was to identify and discuss approaches related to, and work done on, the timescales issue within national radioactive waste management programmes in the context of assessing post-closure safety. The proceedings include the presentations made as well as a summary of the discussions held.

Book Description
This Safety Requirements publication is concerned with providing protection for people and the environment from the hazards associated with waste management activities related to disposal, i.e. hazards that could arise during the operational period and following closure. It sets out the protection objectives and criteria for geological disposal and establishes the requirements that must be met to ensure the safety of this disposal option, consistent with the established principles of safety for radioactive waste management. It is intended for use by those involved in radioactive waste management and in making decisions in relation to the development, operation and closure of geological disposal facilities, especially those concerned with the related regulatory aspects.

Book Description
Deep Geological Disposal of Radioactive Waste presents a critical review of designing, siting, constructing and demonstrating the safety and environmental impact of deep repositories for radioactive wastes. It is structured to provide a broad perspective of this multi-faceted, multi-disciplinary topic: providing enough detail for a non-specialist to understand the fundamental principles involved and with extensive references to sources of more detailed information. Emphasis is very much on "deep” geological disposal - at least some tens of metres below land surface and, in many cases, many hundred of metres deep. Additionally, only radioactive wastes are considered directly - even though such wastes often contain also significant chemotoxic or otherwise hazardous components. Many of the principles involved are generally applicable to other repository options (e.g. near-surface or on-surface disposal) and, indeed, to other types of hazardous waste. Presents a current critical review in designing, siting, constructing and demonsrating the safety and environmental impact of deep repositories for radwaste Addresses the fundamental principles of radioactive waste with up-to-date examples and real-world case studies Written for a multi-disciplinary audience, with an appropriate level of detail to allow a non-specialist to understand

Book Description
This handbook is concerned with developing principles and standards for the safe disposal of solid radioactive wastes by burial deep in the Earth's crust. Radioactive wastes have focussed thinking on long-term environmental protection issues in an unprecedented way. Consequently, the way in which principles and standards are set, and the thinking behind this, is of wider interest than to the nuclear field alone. The issues are not just technical and scientific. There is also a much wider philosophical context to the debate, centering on ethics, human values and the expectations of society.In this handbook it is intended that all theses issues are brought together, suggesting appropriate ways forward in each area, culminating in a proposed structure for safety regulations. It also aims to provide a detailed discussion of some of the most difficult logical an ethical issues facing those wishing to dispose of long-lived radioactive wastes.

Book Description
These workshop proceedings highlight the significant amount of work accomplished over the past decade in delivering transparent, proportionate regulation for geological disposal, and identify important differences between national regulations even if these are not in contradiction with international guidance. They also underline the importance of R&D carried out on behalf of the regulator. In addition To The contributed papers, these proceedings trace the numerous discussions that formed an integral part of the workshop. They constitute an important and unique documentary basis for researchers and radioactive waste management specialists. Themes addressed include duties to future generations, timescales for regulation, stepwise decision making, roles of optimisation and best available techniques (BAT), multiple lines of reasoning, safety and performance indicators, recognition of uncertainties And The importance of stakeholder interactions.

Book Description
Regulating the long-term safety of geological disposal of radioactive waste is a key part of making progress on the radioactive waste management issue. A survey of member countries has shown that differences exist both in the protection criteria being applied and in the methods for demonstrating compliance, reflecting historical and cultural differences between countries which in turn result in a diversity of decision-making approaches and frameworks. This conference proceedings presents discussions focused on diversity in regulatory processes; the basis and tools for assuring long-term protection; ethical responsibilities of one generation to later generations and how these can be discharged; and adapting regulatory processes to the long time frames involved in implementing geological disposal. These proceedings include a summary of the viewpoints expressed as well as the 22 papers presented at the workshop.--Publisher's description.
