Le réaménagement de l’environnement des sites des mines et usines de traitement d’uranium a pris un tournant majeur depuis quelques décennies. Les raisons de cette évolution sont multiples : un grand nombre d’installations ont été fermées ; la décontamination des anciens sites abandonnés est un souci croissant ; enfin, des règlements toujours plus stricts sont mis en place en vue de protéger l’environnement. Des programmes de réaménagement sont donc instaurés dans le but de rétablir l’environnement initial des sites contaminés ou de permettre l’utilisation libre des sols, le tout dans un cadre qui sache respecter les objectifs du développement durable à long terme et qui convienne à toutes les parties prenantes. Ce rapport résume les pratiques et les enjeux les plus importants des programmes visant à réaménager les installations de production d’uranium, puis brosse le tableau général des activités et des programmes spécifiques dans les pays participant à l’étude. Les thèmes abordés sont variés : caractérisation des sites, démantèlement et déclassement, installations de gestion des déchets, décontamination de l’eau, intendance et surveillance de longue durée, politiques et réglementation, et coûts. Les profils nationaux des activités et programmes de réaménagement s’appuient sur les réponses fournies par chacun des 22 pays (12 pays Membres de l’OCDE et 10 pays non membres) qui ont participé à l’enquête et comprennent des informations liées aux questions qui sont réputées les plus importantes dans chacun d’entre eux.

The ""Red Book"", jointly prepared by the OECD Nuclear Energy Agency and the International Atomic Energy Agency, is a recognised world reference on uranium. Its contents are based on official information received from 45 countries, supplemented by unofficial information for two others. This edition, the 19th, presents the results of a thorough review of world uranium supply and demand as of 1 January 2001 and provides a statistical profile of the world uranium industry in the areas of exploration, resource estimates, production and reactor-related requirements. It provides substantial new info

The societal aspects of risk governance are increasingly becoming a part of public decision-making processes. This tendency is particularly evident in matters dealing with the protection of human health and the environment. The NEA Committee on Radiation Protection and Public Health organised a workshop to examine stakeholder involvement processes through which governments and regulators can arrive at accepted decisions regarding radiological protection. An example of an area in which stakeholder involvement is important is the clean-up of sites contaminated by accidents or by past industrial or research activities. These proceedings address the roles of various stakeholders in the decision-making process, and their expectations regarding how a modern system of radiological protection should be integrated within the broader context of risk governance. Case studies are presented to illustrate good practice and as a basis for drawing conclusions regarding general lessons that can be applicable in many different national contexts. These proceedings will be of interest to policy makers, radiation protection experts and interested members of the public.

The four articles of the present volume address very different topics in nuclear physics and, indeed, encompass experiments at very different kinds of exp- imental facilities. The range of interest of the articles extends from the nature of the substructure of the nucleon and the deuteron to the general properties of the nucleus, including its phase transitions and its rich and unexpected quantal properties. The first article by Fillipone and Ji reviews the present experimental and theoretical situation pertaining to our knowledge of the origin of the spin of the nucleon. Until about 20 years ago the half-integral spin of the neutron and p- ton was regarded as their intrinsic property as Dirac particles which were the basic building blocks of atomic nuclei. Then, with the advent of the Standard Model and of quarks as the basic building blocks, the substructure of the - cleon became the subject of intense interest. Initial nonrelativistic quark m- els assigned the origin of nucleon spin to the fundamental half-integral spin of its three constituent quarks, leaving no room for contributions to the spin from the gluons associated with the interacting quarks or from the orbital angular momentum of either gluons or quarks. That naive understanding was shaken, about fifteen years ago, by experiments involving deep-inelastic scattering of electrons or muons from nucleons.

The present review volume not only covers a wide range of topics pertinent to nuclear science and technology, but has attracted a distinguished international authorship, for which the editors are grateful. The opening review by Drs. Janet Tawn and Richard Wakeford addresses the difficult matter of questioning sci- tific hypotheses in a court of law. The United Kingdom experienced a substantial nuclear accident in the 1950s in the form of the Windscale Pile fire. This in itself had both good and bad consequences; the setting up of a licensing authority to ensure nuclear safety was one, the understandable public sentiment concerning nuclear power (despite the fire occurring in a weapons pile) the other. Windscale today is subsumed in the reprocessing plant at Sellafield operated by British Nuclear Fuels plc and it was inevitable perhaps that when an excess cluster of childhood leukaemia was observed in the nearby village of Seascale that public concern should be promoted by the media, leading to the hearing of a claim of compensation brought on behalf of two of the families of BNFLs workers who had suffered that loss. The review article demonstrates the complexity of und- standing such a claim against the statistical fluctuations inherent and shows how the courts were persuaded of the need to propose a biological mechanism if responsibility were to be held. The Company were undoubtedly relieved by the finding.
