Based on the authors' recent investigations, this book describes the application of glassy and polyphase composite materials for nuclear waste immobilisation. It introduces immobilisation issues beginning with a short description of nuclear waste types and compositions. Sources of nuclear waste are described including the nuclear fuel cycle, operational and spent nuclear fuel reprocessing waste streams. The glassy waste forms currently being used for high-, intermediate- and low level radioactive waste immobilisation are described. Problems related to immobilisation capacity, process efficiency and long-term radionucleide retention are highlighted. Scientific and technical problems in nuclear waste immobilisation are emphasised in particular long-term waste form stability and durability. Recent developments in advanced nuclear waste forms are described such as glass composite materials (GCM) with higher versatility and waste loading. New immobilisation approaches and technologies are described including advanced cold crucible induction melting (CCM), self sustaining thermochemical immobilisation (SSI), and in-situ self-sintering in deep underground repositories. Long-term durability tests of nuclear waste glasses are outlined and the role of ion-exchange phase in glass corrosion is described in detail.

This book offers a complete panorama of the pressurized water reactor industry, beginning from its origin in the USA and the realization of nuclear engines for naval propulsion, to its most recent developments in the field of civil energy production, particularly in France with the 56 reactors of the multinational electric utility company, Electricité de France (EDF). This comprehensive two-volume masterwork features detailed descriptions of all the crucial components driving a pressurized water nuclear reactor. Volume 1 deals with the main components, such as the main primary circuit, the reactor core, and the steam generators. Volume 2 covers the secondary circuit and the cold source, including components such as the turbine, condenser, alternator, transformers and power supply. Written by Serge Marguet, a leading specialist in reactor physics and author of several books on the subject, this book draws on his experience of more than 35 years in research and development at EDF, a global leader in civil nuclear energy. Featuring a richly illustrated, full-color iconography, as well as a detailed index and bibliography, The Technology of Pressurized Water Reactors is an indispensable work for seasoned nuclear energy professionals, as well as inquisitive newcomers to the field.

In its present condition, the dam of the tailings pond is less stable than is recommended by international practice. A surveillance system has been established to observe both vertical and horizontal soil movement and the buildup of stresses in the soil. The stability of the dam depends primarily on erosion by shore processes and the consequent reduction of the counterbalance, as well as the reduction in strength of the Cambrian clay underlying the dam caused by creep and by water percolating to the bottom of the pond. The most critical need is to enlarge the counterbalance and to stop erosion. The surveillance system should be supplemented with a system of inclinometers. Monitoring of coastal processes should be continued. At present, the hydrodynamic stress on the dam is minimal because the pebble layer allows drainage of water out of the tailings pond and into the sea. The regulatory requirement to end emissions into the Baltic Sea must be met without causing undesirable hydrodynamic stresses on the dam. This could be done by covering the pond and diverting precipitation water. 9. References I. Report on Topographic-Geodetic Studies at the Tailings Pond. 1965, No. A-4-01187 (in Russian). 2.
