文摘
- •
Vickers microhardness and Young's modulus data of high burnup fuels are presented.
- •
The data are compared to fuel performance codes' correlations.
- •
A burn-up dependent factor is introduced for the Young's modulus of irradiated fuel.
- •
The modification extends ranges of experimental validation of the code correlation.
- •
The new burn-up dependent factor has limited effect on integral fuel performance.
