This book was released on 2012-06 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication reports on the results of a coordinated research project on advances in high temperature gas cooled reactor (HTGR) fuel technology and describes the findings of research activities on coated particle developments. These comprise two specific benchmark exercises with the application of HTGR fuel performance and fission product release codes, which helped compare the quality and validity of the computer models against experimental data. The project participants also examined techniques for fuel characterization and advanced quality assessment/quality control. The key exercise included a round-robin experimental study on the measurements of fuel kernel and particle coating properties of recent Korean, South African and US coated particle productions applying the respective qualification measures of each participating Member State. The summary report documents the results and conclusions achieved by the project and underlines the added value to contemporary knowledge on HTGR fuel.

Download or read book An Assessment of the Methods for Determining Defect Or Failure Fractions in HTGR Coated Particle Fuels and Their Relationship to Particle Microstructure written by and published by . This book was released on 1989 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: The methods for determining the fraction of defective or failed coatings in high-temperature gas-cooled reactor (HTGR) fuel particles, the burn-leach and acid leach methods, are critically analyzed. Evaluation of the method reveals that (1) the efficacy of the methods is limited by access, for leaching and oxidizing fluids, to the interior of defective or failed coatings; (2) the coating defects can be characterized in terms of pores by a distribution of effective pore radii; (3) effective pore radii significantly less than several, hundred nanometers cannot be detected; and (4) pore radii less than the latter limit may contribute significantly to fission product release from the defective or failed particles. The currently used methods are thus inadequate for detecting defective or failed fuel particle coatings. The development of better methods is recommended; the intrusion method, by which a portion of the distribution of effective pore radii was determined in the analysis from limited previous measurements, is suggested as one suitable basis for the development. 32 refs., 10 figs., 11 tabs.

Download or read book Analysis of Chemical Failure of Coated UO$sub 2$ and Other Oxide Fuels in the High-temperature Gas-cooled Reactor written by and published by . This book was released on 1974 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The thermodynamic data for unirradiated dioxides in the U- ThPu-O system are briefly reviewed. Calculations of oxygen release during fission were made and were found to agree qualitatively with experimental measurements. Theories were developed for prediction of mass transport rates in oxide particles; these included control by either CO-- CO/sub 2/ diffusion, reactions such as disproportionation of carbon monoxide, or solid-state diffusion through the kernel. Methods were devised for the determination of the general type of rate- controlling mechanism from the quantitative analysis of inreactor and out-of- reactor experiments. Application of these methods to an in-pile experiment indicated that CO-- CO/sub 2/ diffusion did not control the rate of UO/sub 2/ or (Th,U)O/sub 2/ migration in BISO particles; instead, control by solid-state diffusion was indicated.

Book Synopsis Failure Mechanisms in High Temperature Gas Cooled Reactor Fuel Particles by :
Download or read book Failure Mechanisms in High Temperature Gas Cooled Reactor Fuel Particles written by and published by . This book was released on 1979 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: BISO coated UO2 and ThO2 particles were heated to high temperatures to determine failure mechanisms during hypothetical loss of coolant scenarios. Rapid failure begins when the oxides are reduced to liquid carbides. Several failure mechanisms are applicable, ranging from hole and crack formation in the coatings to catastrophic particle disintegration.
