Book excerpt: Zircaloy-4 fuel sheath specimens 15.2 mm diameter by 0.42 mm wall thickness with beryllium-brazed appendages have been laboratory tested at high temperature with internal gas pressurization and inert gas shielding of the outer surfaces. with sufficient hoop stress at temperatures less than 1073 k cracks, which were due to a beryllium assisted crack penetration mechanism, were found to occur at the appendages. formulae to predict the beryllium penetration and rupture have been derived by westinghouse canada ltd. based on data from direct resistance-heated specimens. the formulae are thought to be able to predict the phenomenon in fuel sheaths with changing temperature/pressure histories. a series of tests was done by canadian general electric to determine the formulae ability to predict the occurrence of beryllium assisted crack penetration in specimens heated indirectly with internal heaters. the tests showed: 1) there is an incubation period before any beryllium assisted crack penetration occurs. 2) at sheath temperatures below approximately equal to 1073 k sheath rupture by excessive mechanical strain will preclude rupture by beryllium assisted crack penetration. 3) the formulae predicted rupture times above and below the braze alloy melting temperature within the previously determined confidence limits. 4) predictions of beryllium assisted crack penetration rupture for specimens with changing temperature/pressure histories were of similar accuracy to predictions of isothermal tests. 5) specimens with an appendage plane of one bearing pad and three spacer pads behaved similarly to the specimens with four spacer pads on which the formulae were based.

This book was released on 2009 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The time-dependent deformation behavior of pressure tubes in CANDUTM (CANada Deuterium Uranium) reactors is an important property that has to be predicted for reactor life management. Measurements accumulated over many years have shown that there is considerable variability in deformation rates between different tubes. The deformation behavior not only varies from tube to tube but also varies along the length of each tube; this axial variation in itself is unique to each tube. The deformation behavior is determined by the microstructure and this is a function of the manufacturing history. An exhaustive study has been conducted to collect and compile deformation and manufacturing data for tubes in many different reactors. The manufacturing data have been analyzed with respect to the measured in-reactor performance of the pressure tubes. Data from pressure tubes fabricated over a 30-year period have been analyzed. During this time the manufacturing parameters have evolved to improve the workability and mechanical properties and also reduce tube-to-tube variability. The effect of manufacturing variables on in-reactor performance has been assessed for tubes that have been in service for many years and approaching the end of their design life. The analysis shows that the two most important factors that affect the deformation behavior of pressure tubes are the material source (ingot) and the extrusion conditions. These are related by the microstructure (texture, grain size, and dislocation density) to the deformation. The results of the statistical analyses will be presented and discussed in terms of the manufacturing conditions that bring about specific microstructures.

Book excerpt: Provides a thorough explanation of the basic properties of materials; of how these can be controlled by processing; of how materials are formed, joined and finished; and of the chain of reasoning that leads to a successful choice of material for a particular application. The materials covered are grouped into four classes: metals, ceramics, polymers and composites. Each class is studied in turn, identifying the families of materials in the class, the microstructural features, the processes or treatments used to obtain a particular structure and their design applications. The text is supplemented by practical case studies and example problems with answers, and a valuable programmed learning course on phase diagrams.
