A discussion considering fatigue design basis (FDB) and fatigue operating basis (FOB) approaches is presented. These two concepts are applied to evaluate the lifetime of typical ASME 3 class 1 components through simplified and detailed stress analysis. The cumulative usage factor (CUF) calculated using S-N fatigue curves available in the ASME 3 are compared to those obtained by S-N curves modified by the reactor environment. Some recommendations are presented to assess the fatigue in nuclear power plants structures.
