Available in PDF, EPUB and Kindle. Book excerpt: Les réacteurs à neutrons rapides refroidis au sodium à cycle uranium 238/plutonium 239, dont la faisabilité technique a déjà été éprouvée, permettent de s'affranchir du problème des ressources d'uranium naturel en réalisant la régénération de l'élément fissile du combustible. En outre, une gestion des déchets visant à réduire la production et la radiotoxicité des actinides mineurs produits par le réacteur peut être mise en œuvre en transmutant les AM en cœur (transmutation homogène). Une autre alternative pour minimiser les déchets est l'utilisation d'un autre couple fertile-fissile: le thorium 232 et l'uranium 233 (Th/U). La comparaison des deux cycles est menée sur les aspects neutroniques et la sûreté et sur la production de déchets, en utilisant un Monte Carlo évoluant. Concernant la radiotoxicité des déchets, même si on ne dégage pas véritablement d'avantages clairs pour un cycle ou l'autre, le cycle Th/U réduit la radiotoxicité durant les périodes où elle est la plus élevée. La transmutation homogène réduit significativement, pour les deux cycles, la radiotoxicité des déchets, de facteurs variables selon la période de temps considéré. Toutefois, elle se fait au détriment d'une augmentation importante de l'inventaire des AM dans le cœur. Si l'on considère la fin de jeu, l'inventaire du cœur du réacteur devient alors un déchet. Le gain apporté par la transmutation, en prenant en compte à la fois la radiotoxicité du cœur et des déchets cumulés, sera quantifié, et montre que la transmutation n'offre pas de gain considérable si l'incinération des éléments fissiles rinci aux Pu ou U selon le c cie n'est as mise en œuvre lors de l'arrêt de la filière.

Download or read book From Microphysics to Macrophysics written by Roger Balian and published by Springer Science & Business Media. This book was released on 2007-06-26 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: This popular, often cited text returns in a softcover edition to provide a thorough introduction to statistical physics and thermodynamics, and to exhibit the universal chain of ideas leading from the laws of microphysics to the macroscopic behaviour of matter. A wide range of applications illustrates the concepts, and many exercises reinforce understanding. Volume II applies statistical methods to systems governed by quantum effects, in particular to solid state physics, explaining properties due to the crystal structure or to the lattice excitations or to the electrons. The last chapters are devoted to non-equilibrium processes and to kinetic equations, with many applications included.

Download or read book Four Laws That Drive the Universe written by Peter Atkins and published by OUP Oxford. This book was released on 2007-09-06 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The laws of thermodynamics drive everything that happens in the universe. From the sudden expansion of a cloud of gas to the cooling of hot metal, and from the unfurling of a leaf to the course of life itself - everything is directed and constrained by four simple laws. They establish fundamental concepts such as temperature and heat, and reveal the arrow of time and even the nature of energy itself. Peter Atkins' powerful and compelling introduction explains what the laws are and how they work, using accessible language and virtually no mathematics. Guiding the reader from the Zeroth Law to the Third Law, he introduces the fascinating concept of entropy, and how it not only explains why your desk tends to get messier, but also how its unstoppable rise constitutes the engine of the universe.

This book was released on 2002 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to increasing interest in high-temperature, gas-cooled reactors (HTGRs) in many countries and the need for improved materials for nuclear applications in high-temperature environments, the NEA organised a Second Information Exchange Meeting on Basic Studies in the Field of High-temperature Engineering. These proceedings provide an overview of the activities being carried out in eight countries, the improvement of material properties for HTGR application, in-core monitoring methods and properties of irradiated graphite, and HTGR fuel fabrication and performance.
