Book Description
La stérilisation par la vapeur d'eau occupe une place privilégiée dans l'hygiène hospitalière. L’infection hospitalière ou nosocomiale désigne toute maladie contractée à l'hôpital, due à des micro-organismes qui affectent soit le malade, soit le personnel hospitalier. Les motivations principales de cette étude sont d'éviter les gouttelettes d'eau qui restent collées à la charge à la fin de la stérilisation. Trois axes de recherche ont été développés. Une étude expérimentale sur l'analyse du comportement thermique de l'enceinte du stérilisateur, a permis d'obtenir les profils de température d'un cycle de stérilisation d'instruments chirurgicaux et montrer l'importance des gradients de température dans l'enceinte de stérilisation. Une simulation numérique du champ des vitesses concerne l'étude locale du système d'injection de vapeur. Cette approche a permis d'appréhender le scenario d'écoulement de la vapeur dans la chambre de stérilisation. Un code de calcul du champ thermique, effectué par la méthode zonale, a été développé pour la phase d'injection de vapeur. Dans le domaine médical, les résultats obtenus constituent une première approche sur l'étude des phénomènes de transferts thermiques dans les stérilisateurs à vapeur.

Book Description
Nuclear engineering has undergone extensive progress over the years. In the past century, colossal developments have been made and with specific reference to the mathematical theory and computational science underlying this discipline, advances in areas such as high-order discretization methods, Krylov Methods and Iteration Acceleration have steadily grown. Nuclear Computational Science: A Century in Review addresses these topics and many more; topics which hold special ties to the first half of the century, and topics focused around the unique combination of nuclear engineering, computational science and mathematical theory. Comprising eight chapters, Nuclear Computational Science: A Century in Review incorporates a number of carefully selected issues representing a variety of problems, providing the reader with a wealth of information in both a clear and concise manner. The comprehensive nature of the coverage and the stature of the contributing authors combine to make this a unique landmark publication. Targeting the medium to advanced level academic, this book will appeal to researchers and students with an interest in the progression of mathematical theory and its application to nuclear computational science.

Book Description
This comprehensive volume offers readers a progressive and highly detailed introduction to the complex behavior of neutrons in general, and in the context of nuclear power generation. A compendium and handbook for nuclear engineers, a source of teaching material for academic lecturers as well as a graduate text for advanced students and other non-experts wishing to enter this field, it is based on the author’s teaching and research experience and his recognized expertise in nuclear safety. After recapping a number of points in nuclear physics, placing the theoretical notions in their historical context, the book successively reveals the latest quantitative theories concerning: • The slowing-down of neutrons in matter • The charged particles and electromagnetic rays • The calculation scheme, especially the simplification hypothesis • The concept of criticality based on chain reactions • The theory of homogeneous and heterogeneous reactors • The problem of self-shielding • The theory of the nuclear reflector, a subject largely ignored in literature • The computational methods in transport and diffusion theories Complemented by more than 400 bibliographical references, some of which are commented and annotated, and augmented by an appendix on the history of reactor physics at EDF (Electricité De France), this book is the most comprehensive and up-to-date introduction to and reference resource in neutronics and reactor theory.

Book Description
Building upon the success of the first edition, the Nuclear Engineering Handbook, Second Edition, provides a comprehensive, up-to-date overview of nuclear power engineering. Consisting of chapters written by leading experts, this volume spans a wide range of topics in the areas of nuclear power reactor design and operation, nuclear fuel cycles, and radiation detection. Plant safety issues are addressed, and the economics of nuclear power generation in the 21st century are presented. The Second Edition also includes full coverage of Generation IV reactor designs, and new information on MRS technologies, small modular reactors, and fast reactors.
