Summary:
Commercially developed 20% cold-worked P,Ti-modified 316 stainless steel claddings were irradiated as fuel pins in C-type irradiation rigs of JOYO under typical fast reactor conditions. The microstructural changes of irradiated claddings at temperatures around 500 °C were extensively analyzed using transmission electron microscopy. Void formation is closely related with M6C and G-phase precipitates and concomitant phosphide dissolution beyond the fast neutron fluence of 15x1026 n/m2. Such phase instability in the fuel pin cladding during the fast reactor operation is caused by the radiation induced solute segregation, and it mainly interpreted in terms of varying system sink strength due to dislocation and precipitate changes
