Book Description
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.
