Book Description
L’utilisation et la gestion de l’énergie nucléaire sont des sujets sensibles. Chaque accident nucléaire majeur qui se produit soulève de nombreuses et nouvelles interrogations sur les risques radioactifs pour l’environnement et la biodiversité, et l’impact des radionucléides sur les êtres vivants et la santé. S’inscrivant au cœur du débat public, Le risque radioactif propose une synthèse complète des connaissances actuelles sur les principaux polluants radioactifs de l’environnement (uranium, transuraniens, isotopes radioactifs du césium, du strontium, de l’iode, du tritium, du carbone et de divers métaux de transition…), leur comportement et leur devenir dans les divers compartiments physiques des milieux et au sein des organismes vivants, dont l’homme. Il présente de façon claire et raisonnée : - les fondements de la physique et de la chimie nucléaires ainsi que leurs applications dans différents domaines (militaire, énergie, médecine, industrie…). Il aborde également les notions à connaître d’écologie et de génétique, et rappelle les origines anthropiques des radionucléides dans l’environnement ; - les grands principes de la radioécologie, discipline consacrée à l’étude des radionucléides, le comportement de ces derniers dans l’environnement (atmosphère, hydrosphère et lithosphère), leur mode de contamination et leur effet néfaste sur les organismes non humains ; - les principaux risques radioactifs pour l’homme (exposition, imprégnation), les mécanismes de contamination et leurs conséquences sur la santé (effets des irradiations) ; - les principaux inconvénients de l’utilisation de l’énergie nucléaire que sont les déchets radioactifs et leur gestion, et les accidents nucléaires et leur impact. Véritable ouvrage de référence multidisciplinaire, Le risque radioactif s’adresse aux ingénieurs, techniciens et industriels concernés par l’évaluation, la prévention et la gestion des risques radioactifs, aux responsables « environnement » des entreprises et collectivités ainsi qu’aux autorités de sûreté nucléaire. Il sera également utile aux enseignants et étudiants de troisième cycle ainsi qu’à toute personne souhaitant mieux comprendre le risque radioactif.

Book Description
The use of atomic energy for military purposes has given rise to a variety of nuclear accidents from the outset. This applies to all levels of use: from the manufacture of weapons to their commissioning. This book provides an overview of the potential impact of such accidents. The prospective consequences of local and global nuclear war are detailed. Similarly, for each accident, the environmental, ecological, health and socio-economic consequences are reviewed. The contamination of the environment and its fauna and flora is detailed and the effects of ionizing radiation are reported. The same is provided for human populations and the adverse effects on the health and physical and mental states of the populations concerned. The economic cost of accidents is also evaluated. The research presented in this book is based on scientifically recognized publications, and reports from the military forces of the various countries concerned and from the national and international organizations competent in this field (IAEA, WHO, UNSCEAR, IRSN, ICPR, etc.).

Book Description
Detailing the estimation and perception of nuclear risk, this book follows military and civilian nuclear accidents, plus the systems put in place by national and international authorities for recording and analyzing feedback. Prevention and anticipation being the best defenses against a nuclear accident, the authorities have also categorized the different types of accidents, and are doing research to better understand and control them. In light of this, this book shows how the authorities take practical measures to protect neighboring populations and limit radioactive contamination of the environment. Frances experience in this arena is well-documented and a chapter of this book is devoted to the fight against terrorist attacks in the nuclear field. Nuclear Accidents is based on scientifically-recognized publications, as well as on reports from the various countries concerned, and the national and international organizations competent in this field (IAEA, WHO, UNSCEAR, IRSN, etc.).

Book Description
The classification of radioactive waste varies from state to state. This results in different management procedures for each country, while following IAEA and OECD/NEA recommendations. Radioactive waste comes from numerous sources. The largest volumes are generated by the decommissioning and dismantling of nuclear facilities. Long-lived, medium- and high-activity waste – categorized as the most hazardous types of waste – are in fact largely produced by nuclear power reactors, spent fuel reprocessing plants and nuclear accidents. Final disposal of very low-activity, low-activity and very short-lived waste is well controlled. However, final solutions for certain categories, including long-lived waste, sorted waste and spent graphite waste, are not yet in place. Management of Radioactive Waste reviews all the possible solutions and presents those chosen by the various states, including a chapter detailing policy on radioactive waste management, taking France as an example.

Book Description
Following the acquisition of the atomic bomb by five states, the United Nations began drafting several treaties to limit nuclear proliferation. These efforts failed, as four more states also acquired nuclear weapons. In a similar vein, an attempt to limit atomic weapons - primarily within the two superpowers - was initiated. While the number of weapons has decreased, the new bombs now being manufactured are more powerful and more precise, negating any reduction in numbers. In the field of civil nuclear use, all nuclear facilities (reactors, factories, etc.) have a limited lifespan. Once a plant is permanently shut down, these facilities must be decommissioned and dismantled. These operations are difficult, time-consuming and costly. In addition, decommissioning generates large volumes of radioactive waste of various categories, including long-lived and high-activity waste. Risks to the environment and to health are not negligible during decommissioning. The International Atomic Energy Agency (IAEA) and the Nuclear Energy Agency (NEA) of the Organisation for Economic Co-operation and Development (OECD) have produced numerous publications with recommendations. Each state has its own decommissioning strategy (immediate or delayed) and final plan for the site - whether it be returning it to greenfield status or obtaining a nuclear site license with centuries-long monitoring.

Book Description
La physique des réacteurs nucléaires est le premier ouvrage français conçu pour aborder de façon progressive et détaillée la complexité théorique du comportement des neutrons, en situation sûre ou accidentelle. Fruit de l’expérience pédagogique de l’auteur et de son expertise internationale reconnue en sûreté nucléaire, il est rapidement devenu un ouvrage de référence au sein de la communauté nucléaire française. Après des rappels de physique nucléaire replaçant les notions théoriques dans leur contexte historique, l’auteur expose les théories mathématico-physiques les plus récentes concernant : • le ralentissement des neutrons dans la matière ; • les particules chargées et les rayonnements électromagnétiques ; • les phases de calcul, en soulignant les hypothèses simplificatrices ; • le concept de criticité, lorsque se développe et s’entretient une réaction nucléaire en chaîne ; • le calcul théorique des réacteurs homogènes et hétérogènes ; • les problèmes d’autoprotection ; • les méthodes numériques des 2 approches historiques du traitement des neutrons (transport neutronique et diffusion). Cette 2e édition, revue et augmentée, approfondit certaines notions, notamment le spectre théorique de fission, l’effet des liaisons cristallines, l’effet de l’hétérogénéité du champ de température, l’effet Dancoff, les équations du transport en géométrie dimensionnelle, le calcul du facteur anti-trappe, la méthode des neutrons pulsés, l’effet d’ombre de l’intégrale de résonance, la méthode Feynman-a, le traitement des instrumentations de l’EPR… Complété par plus de 400 références bibliographiques, dont de nombreuses commentées et une annexe replaçant les travaux d’EDF dans le contexte national du développement de l’énergie nucléaire, cet ensemble constitue la référence théorique la plus complète en neutronique. Cet ouvrage est conforme aux enseignements de l’Institut de transfert de technologie d’EDF et sert de référentiel aux enseignements de l’École nationale supérieure d’ingénieurs de Bourges (INSA-Centre Val de Loire). Il a été conçu pour les ingénieurs et techniciens sur sites souhaitant enrichir leur propre expertise, pour les étudiants de 3e cycle et les élèves ingénieurs en sciences énergétiques.
