文摘
- •
Numerical modeling to analyze lower head wall thermal erosion was completed and validated.
- •
Thermal erosion mechanisms of lower head wall by molten corium jets were revealed.
- •
The crust formed at the interface of melt jet and lower head wall could delay the thermal erosion.
- •
An approach of coating a ZrO2 liner to delay the erosion was proposed.
