To achieve rational maintenance for fossil power plants, prediction of remaining life for structure components is quite important. Precise evaluation of critical flaw sizes, which provides failure criteria of the components with postulated crack-like-flaws under a specific operating condition, is one of the key issues. In this paper, the effects of structural or material properties on the critical crack sizes were investigated by means of R6 based analyses. Subsequentry, the crack evaluation method for CrMoV cast alloy were proposed according to the analysis results, and a crack evaluation case study was demonstrated using the proposed method.
