Description

This paper deals with a probabilistic analysis for Creep Crack Growth (CCG) behavior of Modified 9Cr-1Mo steel for next generation nuclear reactors. The CCG data were obtained by the CCG tests performed on 1/2Compact Tension (CT) specimens under the applied load of 5000N at the identical temperature condition of 600 .deg. C. The CCG behavior was analyzed statistically by using the empirical equation between the CCG rate, da/dt and C* parameter. The B and q values were investigated by the least square fitting method for each specimen. The probabilistic distribution functions for the B and q were investigated by using the normal, log-normal and weibull distribution. It appeared that the results of the B and q constants followed Log-normal distribution well. From this result, it was identified that the CCG rate could be evaluated probabilistically for Modified 9Cr-1Mo steel.
