Description
The transient fuel pellet-cladding interaction (PCI) of liquid-metal fast breeder reactor (LMFBR) fuel elements or rods is analyzed based on experimental results. The heat generation, ramp linear power rating, fuel restructuring, temperature distribution, bonding gap conductance, irradiation swelling, irradiation creep, fuel burnup, fission gas release, fuel pellet and cladding cracking, crack healing, radiation and oxidation corrosion, stress fatigue cracking, stress corrosion cracking, fuel performance, and reactor safety are taken into consideration. To improve the mixed (U, Pu)O2 or (U, Pu)C fuel performance and reactor safety, it is desired to: (a) increase the strength and ductility of structural material; (b) provide adequate gap distance and plenum space; (c) keep ramp-power increase rate slow, and (d) reduce the intensity and frequency of transient PCI in order to minimize SFC and SSC.
