Book excerpt: CETTE THESE FAIT PARTIE D'UN PROGRAMME DE RECHERCHE ET DE DEVELOPPEMENT POUR LA MISE AU POINT D'UNE TECHNIQUE DE PRODUCTION DE FAISCEAUX D'IONS RADIOACTIFS RICHES EN NEUTRONS. LA METHODE (BASEE SUR LE PRINCIPE ISOL) CONSISTE A PRODUIRE DES NEUTRONS PAR INTERACTION D'UN FAISCEAU DE DEUTONS AVEC UNE CIBLE EPAISSE, PUIS A UTILISER CES NEUTRONS AFIN DE FAIRE FISSIONNER UNE CIBLE D'URANIUM 238 ET ENFIN A EXTRAIRE ET A ACCELERER LES PRODUITS DE FISSION RICHES EN NEUTRONS POUR EN FAIRE UN FAISCEAU. LES DIVERSES ETUDES DU PROGRAMME SONT REGROUPEES AU SEIN DE DEUX PROJETS PARRNE (PRODUCTION D'ATOMES RADIOACTIFS RICHES EN NEUTRONS) ET SPIRAL-II (SYSTEME DE PRODUCTIONS D'IONS RADIOACTIFS ACCELERES EN LIGNE). LA PRODUCTION ET LA DETECTION DES FAISCEAUX SECONDAIRES DE NEUTRONS UTILISES POUR FAIRE FISSIONNER LA CIBLE D'URANIUM CONSTITUENT LE THEME CENTRAL DE LA THESE. APRES UNE ETUDE BIBLIOGRAPHIQUE QUI MONTRE QUE LES DEUTONS SONT LES PROJECTILES DE CHOIX POUR LA PRODUCTION DES NEUTRONS, TROIS SUJETS ONT ETE ETUDIES PLUS PARTICULIEREMENT AU COURS DE CE TRAVAIL : - L'EXTENSION DE LA TECHNIQUE DES DETECTEURS A ACTIVATION POUR LA MESURE DE SPECTRES DE NEUTRONS DANS UNE LARGE GAMME D'ENERGIE (1 A 150 MEV), - LA MESURE EXPERIMENTALE A PLUSIEURS ANGLES DES SPECTRES DE NEUTRONS PRODUITS PAR INTERACTION ENTRE DES DEUTONS (DE 17 A 200 MEV) AVEC DES CIBLES EPAISSES (BE, C ET U), - LE DEVELOPPEMENT D'UN MODELE SIMPLE PERMETTANT DE REPRODUIRE ET PREDIRE LES DISTRIBUTIONS ANGULAIRES ET LES DISTRIBUTIONS EN ENERGIE DES NEUTRONS PRODUITS PAR UN FAISCEAU DE DEUTONS D'ENERGIE QUELCONQUE DANS UN CONVERTISSEUR DE COMPOSITION QUELCONQUE. CETTE ETUDE A PERMIS DE CONCLURE QUE POUR NOTRE APPLICATION LE CARBONE EST LE CONVERTISSEUR LE MIEUX ADAPTE (SAUF CAS TRES PARTICULIER) ET QUE L'ENERGIE OPTIMALE DES DEUTONS A UTILISER DEVRAIT SE SITUER AUX ALENTOURS DE 100 MEV.

Book excerpt: CETTE THESE S'INSCRIT DANS LE CADRE DU PROJET DE RECHERCHE ET DEVELOPPEMENT PARRNE (PRODUCTION D'ATOMES RADIOACTIFS RICHES EN NEUTRONS) QUI CONSISTE A EXPLORER EXPERIMENTALEMENT LA FISSION DE L'URANIUM 238 INDUITE PAR DES NEUTRONS RAPIDES COMME MODE DE PRODUCTION EN VUE DE REALISER DES FAISCEAUX D'ISOTOPES RADIOACTIFS RICHES EN NEUTRONS. LE FLUX DE NEUTRONS RAPIDES EST PRODUIT PAR L'ARRET D'UN FAISCEAU DE DEUTONS DANS UN CONVERTISSEUR. DES CIBLES EPAISSES DE CARBURES D'URANIUM ET D'URANIUM LIQUIDE ONT ETE MISES AU POINT AFIN DE PERMETTRE UN RELACHEMENT RAPIDE DES FRAGMENTS DE FISSION RADIOACTIFS. A L'AIDE D'UN DISPOSITIF PERMETTANT DE PIEGER SUR UN DOIGT CRYOGENIQUE LES GAZ RARES RELACHES PAR LA CIBLE, DES ISOTOPES DE QUELQUES SECONDES DE PERIODES ONT ETE OBSERVES. CE DISPOSITIF INSTALLE AUPRES DE DIFFERENTS ACCELERATEURS DE DEUTONS A PERMIS D'ETUDIER LA PRODUCTION DE GAZ RARES RICHES EN NEUTRONS A DIFFERENTES ENERGIES DE DEUTONS, DANS LE CADRE DE LA COLLABORATION EUROPEENNE SPIRAL II. UNE EXPERIENCE DE CALIBRATION A MONTRE LA POSSIBILITE D'INSTALLER UN SEPARATEUR D'ISOTOPES EN LIGNE DE TYPE ISOL AUPRES D'UN ACCELERATEUR TANDEM 15 MV POUVANT FOURNIR 500 NA DE DEUTONS A 26 MEV POUR EXPLORER EXPERIMENTALEMENT LA FISSION INDUITE PAR NEUTRONS RAPIDES COMME MODE DE PRODUCTION. DES FAISCEAUX DE ZINC, DE KRYPTON, DE RUBIDIUM, DE CADMIUM, D'IODE, DE XENON ET DE CESIUM ONT ETE PRODUITS AUPRES DE CETTE INSTALLATION. LES FAISCEAUX LES PLUS INTENSES ATTEIGNENT DIX MILLES NOYAUX PAR MICROCOULOMB AVEC DES DEUTONS DE 26 MEV. UN GAIN D'ENVIRON DEUX ORDRES DE GRANDEUR PEUT ETRE OBTENU EN UTILISANT UNE SOURCE D'IONS PLUS SPECIFIQUE ET EN AUGMENTANT L'EPAISSEUR DE LA CIBLE. UN GAIN SUPPLEMENTAIRE DE DEUX ORDRE DE GRANDEUR S'OBTIENT EN AUGMENTANT L'ENERGIE DES DEUTONS A 100 MEV.

Download or read book Nuclear Computational Science written by Yousry Azmy and published by Springer Science & Business Media. This book was released on 2010-04-15 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Presented here is a new and rapidly developing branch of kinetics - the kinetics of processes in structured systems. The book describes dynamic processes that occur in network-forming polymerization systems, in percolation, in the spread of a disease, and in the growth of a cancer. The dynamic processes in photoconductors are examined along with membrane-mimetic systems of micelles and vesicles, monolayers and membranes, polymer welding, and in chemical reactions that oscillate in space or time. It also develops systems in chemistry, biology, physics and materials science from the teaching level to that of the most recent research.
