Principles And Standards For The Disposal Of Long Lived Radioactive Wastes

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.

A considerable level of international experience has been gained over the last decades in designing radioactive waste disposal facilities. This publication is intended to assist Member States in planning for the disposal of radioactive waste. Specifically, this publication describes the approaches and principles to be considered by the responsible organizations within a Member State involved in the planning and design of radioactive waste disposal facilities. Examples are provided for all waste classes requiring disposal. The examples are based on successfully implemented designs or on design concepts that are sufficiently advanced to demonstrate their overall feasibility for the safe disposal of radioactive waste. Alternate disposal options are also discussed, describing solutions that rely on the conversion of existing facilities, such as mines or other underground openings as well as the potential for disposal in boreholes.

Outlines various possibilities for the development of a classification system for radioactive wastes. This guide proposes a modified classification system with general quantitative boundaries and gives guidance for the development of quantitative classification systems.

Safety and environmental impact is of uppermost concern when dealing with the movement and storage of nuclear waste. The 20 chapters in 'An Introduction to Nuclear Waste Immobilisation' cover all important aspects of immobilisation, from nuclear decay, to regulations, to new technologies and methods. Significant focus is given to the analysis of the various matrices used in transport: cement, bitumen and glass, with the greatest attention being given to glass. The last chapter concentrates on the performance assessment of each matrix, and on new developments of ceramics and glass composite materials, thermochemical methods and in-situ metal matrix immobilisation. The book thoroughly covers all issues surrounding nuclear waste: from where to locate nuclear waste in the environment, through nuclear waste generation and sources, treatment schemes and technologies, immobilisation technologies and waste forms, disposal and long term behaviour. Particular attention is paid to internationally approved and worldwide-applied approaches and technologies. * Each chapter focuses on a different matrix used in nuclear waste immobilisation: 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.
