INTRODUCTION As in other sources of energy, nuclear electricity generation produces waste materials which must be disposed of in a safe and economical way. In recent years particular attention has been focused on disposal of the highly radioactive wastes, either as spent nuclear fuel or as the by-products of nuclear fuel reprocessing. Relatively small volumes of these highly radioactive wastes have been produced so far, but increasing amounts are being generated as the installed nuclear generating capacity grows. At present, in the OECD area, there are no operational disposal facilities for these wastes, due partly to the lack of an immediate need. A considerable research effort is however devoted to development of acceptable disposal options. The greatest part of this effort is directed towards assessment of the feasibility and long- term safety of disposal into deep stable geological formations. Such formations offer the prospect of isolation of the waste from the biosphere and an assurance that radioactive materials will never present an unacceptable hazard to man's environment. This report presents brief descriptions of research activities in the OECD area, including those supported by the CEC and OECD Nuclear Energy Agency (NEA), which contribute to the development of safe options for the disposal of radioactive waste deep underground. It covers principally geological disposal options for high- level radioactive wastes from nuclear fuel reprocessing and spent nuclear fuel, but some form of geological disposal may also be appropriate for other radioactive wastes which may remain potentially hazardous for long periods of time. In a short report it is impossible to do justice to all experimental research related to underground disposal of radioactive waste. This report highlights a number of activities which illustrate the current emphases. There are a large number of very specific research activities which, for reasons of space, are not mentioned here but which are described in other NEA publications. In the field of radionuclide migration, the reader is referred to the bi-annual NEA Newsletter and to the recently published compendium of research activities.
