N2 - A probabilistic fracture model is applied to irradiation assisted stress corrosion cracking effect, assuming
that the oxidized part of stainless steel sample plays an essential role in the crack initiation, propagation
and the sample failure. The Weibull statistical distribution of time-to-failures, estimated through the
correlation with the statistical distribution of oxide strengths, including both the surface oxide layer and
oxidized grain boundaries, fully describe the experimental scatter obtained in the constant load time-tofailure
tests. Large failure uncertainties in these type of tests originate from an intrinsic stochastic
behavior of the oxide cracking due to subcritical crack propagation process.
