摘要

The JSME Codes and Standards Committee have provided many kinds of crack growth rates of SCC and fatigue cracking as Appendix in the code and the code cases. However each code has been separately investigated and there is no common rule among SCC growth rates or fatigue crack growth rates. The working group (WG) members discussed to construct the common rules for fatigue crack growth. Sensitivity study for loading rise time in PWR environment was investigated with slower rise time. Using the proposed common rule, the subgroup (SG) on Evaluation and Standard will transfer the fatigue crack growth rates in the code cases to the code.
