The hypothetical scenario of a control rod ejection in a Pressurised Water Reactor leads to a Reactivity Initiated Accident (RIA [1]) triggering rapid thermal expansion of the pellet. Theses conditions result in a strain-controlled loading on the cladding with large strain rate (about 1s-1). Because the cladding does not have time to increase in temperature, its ductility is limited. Such strain rates are high enough to enhance adiabatic conditions, in which localized heating due to rapid plastic deformation could be significant enough to lead to material softening. Tensile tests at strain rates ranging from 0.1s-1 to 10s-1 and temperatures ranging from 25°C to 480°C were performed on cold-worked Zircaloy-4 samples. All tests were monitored...
