Abstract
The properties of materials of the heat-exchange equipment components of the fast breeder reactor BN-600 after 130000–170000 h of operation at 500–550°C are studied. The effect of long-term aging on the strength, ductility, impact strength, and fracture toughness of 18Cr-9Ni steel (type 304 stainless steel) and its welds is examined. The mechanisms that give rise to changes in the mechanical properties are analyzed on the basis of microstructural and fractographic studies. The predicted degradation of material properties is estimated as a function of operating temperature and time.
