Abstract Scope |
Zirconium is mainly used as fuel cladding in nuclear reactors due to its advantages. However, zirconium hydrides formed inside the cladding degrade the integrity of the cladding making it brittle and prone to cracking. Therefore, understanding the hydride formation is necessary. The hydrides can be classified into two types: intergranular and intragranular. We developed a model that comprehensively considers the texture of the Zr and the crystallographic orientation of the hydride in polycrystalline Zr to show the formation of hydrides and the interaction between grain boundaries and intergranular hydrides. We considered the morphology evolution of the hydrides and grain growth simultaneously and analyzed the effect of the Zr texture on the hydride formation. In addition, we analyzed the correlation between the type of intergranular hydrides and the interacting angle which is the angle between the basal plane and grain boundary using phase-field modeling. |
