Available in PDF, EPUB and Kindle. Book excerpt: The oxidation of core graphite by steam of air represents a problem area of significant concern in safety analyses for the high temperature gas cooled reactor (HTGR). Core and core-support graphite integrity and strength deteriorate with oxidation of the graphite, and oxidation furthermore could affect the rate of fission product release under upset conditions. Consequently, modeling of core response during steam or air ingress conditions requires an expression for the rate of graphite interaction with those impurities. The steam--graphite reaction in particular is a complex interaction of mass transport within the graphite with chemi-sorption and reaction on accessible surfaces; experimental results from graphite to graphite are highly variable, and the description of the reaction is not yet completely consistent. A simple etch pit model relating surface area to burnoff has been proposed and shown to provide reasonable correlation with experimental data obtained from steam oxidation studies of nuclear grade H-327 graphite. Unaccounted differences between theory and experiment arise at burnoffs exceeding 3 to 5 percent. The model, while not complete nor comprehensive, is consistent with experimental observations of graphite oxidation by O2(air), CO2, or H2O, and could have some utility in safety analysis.

This book was released on 2012-12-06 with total page 621 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade there has been a renewed interest in under standing from a fundamental point of view the gasification of carbon. Basi cally there are two major issues in controlling the reactivity of carbon: i) reduction of the gasification rate of carbon materials in hostile environment ii) increase of the gasification rate in order to utilize carbonaceous compounds more effectively. Although these two objectives look somewhat contradictory, they are part of the general topics of understanding gasification reactivity of carbon. Refractory applications of carbon in furnace linings, seals and vanes, as well as the use of carbon-carbon or carbon-ceramic composites in struc tures able to withstand corrosion at high temperature require a better understanding of the fundamentals involved in carbon-oxidizing gas (02' CO , H 0) reactions. Furthermore a great interest of aluminium producers 2 2 is 10 extending the lifetime of carbon electrodes in alumina electrolysis which primarily depends on reducing their consumption rates by air or carbon dioxide. Proper control of gasification reactions is also of prime importance in manufacturing carbonaceous adsorbents like granular activated carbon clothes of high adsorption characteristics. The balance between increase of porosity and decrease in mechanical strength during activation is critical for developing new porous types of carbon materials in particular for carbon clothes and this can only be achieved by a careful control of the gasification reaction.

Available in PDF, EPUB and Kindle. Book excerpt: "This compendium is dedicated to Professor Stanford Solomon Penner in celebration of his seventieth birthday. The authors are his former students, associates, and friends, who have been profoundly influenced by him, primarily as a consequence of the example he set forth by his own work and habits, as well as by the leadership he provided in many technological endeavours." "As one of the most prominent scientists of our times he has been particularly instrumental in advancing the frontiers of combustion technology, while, concomitantly, developing quantitative spectroscopy into a significant diagnostic discipline and assuming a world-renown position of leadership in energy issues. This book consists of papers in the fields of energy, combustion, and spectroscopy - subjects resplendent with his pioneering contributions. Among the topics included here are turbulent combustion, flame structure, detonation, spectroscopic diagnostics, spectroscopy of atmospheric gases and physical problems associated with nuclear reactors, as well as electric power distribution and energy conservation." "Contained here also is his remarkable curriculum vitae and the formidable list of his publications. The editors take this opportunity of conveying to him their best wishes for continuing productive scholarship - the trademark of his life - for many years to come."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
