Time-dependent plastic deformation – creep is one of the most important degradation factors which govern the life of zirconium alloys used as fuel claddings materials in the light water reactor in nuclear power industry. This work aims to describe creep testing of Zr1%Nb (modified E110 alloy) cladding tubes used in the VVER-type reactor. In addition to a standard creep testing method under constant tensile test a nonstandard special creep testing method which has been developed to measure very small creep strains at stresses corresponding to the loading in real service.
