Abstract
In the early 1990th the research program to investigate experimental fuel rods with different fuel compositions and claddings in the research reactor MIR was carried out by JSC “SSC Research Institute of Atomic Reactors” and JSC “VNIINM”. Reexamination of the program reports containing results of postirradiation tests allows ascertaining that some rods with the zirconium alloy E110 cladding tubes were subjected to the power ramp conditions. As a result some rods failed, but one of them demonstrated axial cracking from one end to the other. Unpublished results of the damaged fuel rods inspection are presented here. Different mechanisms of the cladding tubes axial cracking have been analyzed. It is shown that the key factors for axial cracking of claddings after power ramps are hydrogen embrittlement and radiation hardening of a material. However, to the moment it is not enough information to exactly select which mechanism of cladding failure was realized.
