This book was released on 1974 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The individual influence of hydrogen content and graphite coating on the iodine stress corrosion cracking susceptibility of zirconium alloys has been investigated using the stressed c-ring and fuel swelling simulation testing techniques. such parameters as hydrogen content, iodine concentration, type of graphite coating, alloy composition and condition of tubing have been examined. fracture topography has been characterized both by optical microscopy and scanning electron microscopy. models have been proposed to account for the resistance to iodine stress corrosion cracking provided by both hydrogen and to a lesser extent, graphite coatings.

Download or read book Effect of Zirconium Oxide on the Stress Corrosion Susceptibility of Irradiated Zircaloy Cladding written by RF. Mattas and published by . This book was released on 1982 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cladding specimens were obtained from two fuel rods irradiated in the Big Rock Point Reactor to a burnup of ~8 gigawatt days per ton. Both claddings had a uniform, thick (~4 μm) zirconium oxide layer on the inner surface. The significant difference between the two rods was the degree of fission-gas release (0.2 versus 14.3 percent). The high-gas-release rod contained a significantly greater amount of fission-product deposits, and, in some areas, breaks in the inner-surface oxide were observed. The cladding speciments, with the fuel removed, were subjected to stress-rupture tests in an iodine environment using internal gas pressurization to evaluate their stress corrosion cracking (SCC) susceptibility. All tests were conducted at an initial iodine concentration of 0.6 mg/cm2 and a temperature of 325°C. Specimens from the high-gas-release rod exhibited signifciantly increased susceptibility to iodine SCC, with a threshold stress level of ~200 MPa as compared with ~280 MPa in the specimens from the low-gas-release rod. The results suggest that the inner-surface oxide provides a barrier to iodine penetration. Hence, the thick unbreached oxide on the low-gas-release rod provided greater resistance to iodine SCC than the breached oxide on the high-gas-release rod.

This book was released on 2012-08-04 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: By drawing together the current theoretical and experimental understanding of the phenomena of delayed hydride cracking (DHC) in zirconium alloys, The Effect of Hydrogen and Hydrides on the Integrity of Zirconium Alloy Components: Delayed Hydride Cracking provides a detailed explanation focusing on the properties of hydrogen and hydrides in these alloys. Whilst the emphasis lies on zirconium alloys, the combination of both the empirical and mechanistic approaches creates a solid understanding that can also be applied to other hydride forming metals. This up-to-date reference focuses on documented research surrounding DHC, including current methodologies for design and assessment of the results of periodic in-service inspections of pressure tubes in nuclear reactors. Emphasis is placed on showing how our understanding of DHC is supported by progress in general understanding of such broad fields as the study of hysteresis associated with first order phase transformations, phase relationships in coherent crystalline metallic solids, the physics of point and line defects, diffusion of substitutional and interstitial atoms in crystalline solids, and continuum fracture and solid mechanics. Furthermore, an account of current methodologies is given illustrating how such understanding of hydrogen, hydrides and DHC in zirconium alloys underpins these methodologies for assessments of real life cases in the Canadian nuclear industry. The all-encompassing approach makes The Effect of Hydrogen and Hydrides on the Integrity of Zirconium Alloy Component: Delayed Hydride Cracking an ideal reference source for students, researchers and industry professionals alike.

Available in PDF, EPUB and Kindle. Book excerpt: The thermodynamics of the zirconium-iodine system are summarized. In the gas phase are four stable species: ZrI4, ZrI3, ZrI2, and ZrI. Their enthalpies of formation and free-energy functions are presented. The only one of those species relevant to stress corrosion cracking (SCC) of zirconium alloys by iodine is the tetraiodide. There are also four solid compounds corresponding approximately in composition to the tetra, tri, di, and monoiodides. Ranges of solid solution composition, enthalpies of formation, and free-energy functions for those phases are given. Thermodynamic information for iodine chemisorbed on zirconium surfaces is also presented. These thermochemical results are used to analyze chemical behavior in situations related to SCC. In particular, reaction of cesium iodide with uranium dioxide in a fuel rod may produce an iodine pressure large enough to result in chemisorbtion of iodine on clean zirconium.
