VVER ballooning experiments

Description

A series of ballooning experiments was performed at the KFKI-AEKI in order to compare the mechanical behaviour and strength of Zircaloy-4 and Zr1%Nb claddings. The effects of temperature, oxidation and iodine absorption on deformation and burst pressure was investigated in almost 100 biaxial tests. Numerical post-test analyses have also been performed with the stand-alone fuel module of the French CATHARE code and the US fuel behaviour code FRAP-T6. Comparing the experimental and the analytical results, relevant differences of high temperature strength due to different α-β phase transition temperature were revealed between the investigated cladding materials.
