Application of the BEPU methodology to estimate the cladding stress in dry storage.
- •
The stress predicted is notably affected by the irradiation history.
- •
Improvements of FGR modelling would significantly enhance the stress estimates.
- •
The prediction uncertainty should not be disregarded when assessing clad integrity.
