CERAMIC FUEL CLADDING FOR INNOVATIVE REACTORS WITH ACCIDENT-TOLERANT FUEL
SSiC cladding of fuel elements opens new promising solutions for innovative reactors:
- Coolant outlet temperatures up to 1000 °C and more for hydrogen production are desirable.
- Aggressive coolants can be seawater – an important safety aspect of reactors for desalination in floating units – or molten salts in reactors with liquid fuel and/or liquid coolant.
- Economical considerations demand fuel for deep burn
On the basis of innovative materials and technologies new fuel elements must be developed which
- permit core outlet temperatures up to 1000 °C and preferably higher
- permit deep fuel-burn-up
- permit the maximum fuel temperature to reach 1800 °C in case of accidents
- tolerate aggressive coolants.
