Reliability Analysis of Main Steam Pipe Containing Defects

Mathematical model of reliability of main steam pipe in power plant was founded by conducting thorough research on crack initiation and growth, considering uniaxial test constants and compact tension constants as random variables. An application example of reliability evaluation of main steam pipe containing initial defect was conducted in this paper using monte carlo method to confirm applicability of this model. The foundation of this model provide scientific basis for reliability evaluation for main steam pipe containing false dismissal detecting initial defect.
