Chapter 2

Design Basis Loads and Qualification


Chapter 2 addresses the normal operating loads and postulated accident loads which govern the design of nuclear power plant systems and components. They include normal loads (weight, pressure, thermal expansion), and occasional or postulated loads such as fluid transients, seismic loads, flow-induced vibration (FIV), loads on buried pipe, fatigue, and thermal stratification. We also address in this chapter the concept of leak before break (LBB).
