Abstract
We estimate the corrosion development and its effects on the
secondary containment vessels of the French nuclear power plants. A
limit state of corrosion is proposed on the basis of the corrosion
effects. Predictive models are used in the frame of a probabilistic
approach in order to assess the in time evolution of the corrosion
risk. The results are compared with the in situ feedback.
