文摘
- •
Advanced cladding yields different reactor performance and safety characteristics.
- •
Differences are due to cladding material properties, reactor physics, and thermal hydraulics characteristics.
- •
Similar reactivity accident neutronic behavior for SiC-SiC-based cladding versus reference Zircaloy cladding.
- •
FeCrAl cladding response indicates similar energy deposition but with shorter pulses of higher magnitude.
- •
Cladding material and fuel design make a difference for core and fuel response.
