Elastic-plastic fracture toughness and tearing instability characteristics of carbon steel for nuclear primary coolant systems
Abstract
In the design of a typical piping system in light water reactor, the various service loads considered are the pressure, dead weight, thermal and seismic loads. However, the design is generally controlled by the load of seismic events, since the primary stresses during the normal operation are usually low. Therefore, the seismic analysis play a central role in the design of piping systems. Pipe cracking tolerance with respest to a seismic event is necessary to be clear for the purpose of the establishment of piping integrity.
