There are several code and standards, handbooks and guidelines for the nuclear power plant maintenance in Japan, the US and EU. They include SCC and fatigue crack growth curves for crack growth calculation. In this paper the authors selected five kinds of codes, standards and guidelines and compared their fatigue crack growth curves for choice of the suitable curves. The feature of each curve was summarized and quantitatively evaluated. JSME maintenance rule and ASME code provide the fatigue crack growth formulae for both ferritic and austenitic steels and consider the environmental effects in some cases. The FITNET curves are categorized in many kinds of metal whereas the FKM guideline and WES procedure provide the common properties applicable to steels generally.
