Book Description
A variety of Zircaloy-2 and Zircaloy-4 cladding tubes with different microstructures has been manufactured. Test rods have been included in two fuel assemblies, and the assemblies have been inserted into the Ringhals 3 pressurized water reactor. Samples from the same cladding tube variants have been subjected to steam autoclave testing in the range 400 to 500°C for different exposure times and have been characterized with respect to their microstructure.

Book Description
Corrosion is an expensive and potentially dangerous problem in many industries. The potential application of different nanostructured materials in corrosion protection, prevention and control is a subject of increasing interest. Corrosion protection and control using nanomaterials explores the potential use of nanotechnology in corrosion control.The book is divided into two parts. Part one looks at the fundamentals of corrosion behaviour and the manufacture of nanocrystalline materials. Chapters discuss the impact of nanotechnology in reducing corrosion cost, and investigate the influence of various factors including thermodynamics, kinetics and grain size on the corrosion behaviour of nanocrystalline materials. There are also chapters on electrodeposition and the corrosion behaviour of electrodeposited nanocrystalline materials. Part two provides a series of case studies of applications of nanomaterials in corrosion control. Chapters review oxidation protection using nanocrystalline structures at various temperatures, sol- gel and self-healing nanocoatings and the use of nanoreservoirs and polymer nanocomposites in corrosion control.With its distinguished editors and international team of expert contributors, Corrosion protection and control using nanomaterials is an invaluable reference tool for researchers and engineers working with nanomaterials in a variety of industries including, aerospace, automotive and chemical engineering as well as academics studying the unique protection and control offered by nanomaterials against corrosion. Explores the potential use of nanotechnology and nanomaterials for corrosion prevention, protection and control Discusses the impact of nanotechnology in reducing corrosion cost and investigates various factors on the corrosion behaviour of nanocrystalline materials Provides a series of case studies and applications of nanomaterials for corrosion control

Book Description
A series of isothermal investigations have been performed in static autoclaves at 623 K in both standard start of cycle coolant and a series of more concentrated lithium and lithium-boron solutions to simulate the environment which might result within a porous oxide due to hideout. In solutions containing 220 ppm of lithium, the presence of as little as 50 ppm of boron had a marked ameliorating effect on the corrosion rates of Zircaloy-4. The quantity of lithium which became incorporated in the scale was less in the presence of boron and, in general, decreased as the boron concentration in the bulk solution increased. Preliminary results under heat flux in similarly concentrated environments have suggested that the results are also applicable to the real situation in a reactor, since the volatilization of boric acid under boiling was not so great that boron was prevented from reducing the corrosion rate. In contrast, experiments with the same lithium concentration but just 10 ppm of boron resulted in consistently higher weight gains than in the lithium-only test, suggesting that the concentration of boron must exceed a certain critical value before corrosion can be inhibited, and that concentrations below this threshold increase corrosion rates.

Book Description
The oxidation rate was found to be relatively insensitive to various types of surface preparations in the temperature range 400 to 700 deg C. No dependence of reaction rate on oxygen pressure was observed. The cubic rate law also was obeyed by foil specimens at 700 deg C; however, the rate constants were slightly larger than values obtained from parallelepiped samples.

Book Description
Annotation The 41 papers of this proceedings volume were first presented at the 13th symposium on Zirconium in the Nuclear Industry held in Annecy, France in June of 2001. Many of the papers are devoted to material related issues, corrosion and hydriding behavior, in-reactor studies, and the behavior and properties of Zr alloys used in storing spent fuel. Some papers report on studies of second phase particles, irradiation creep and growth, and material performance during loss of coolant and reactivity initiated accidents.
