Conclusions1.Given the current technology for making and constructing 440- and 1000-MW power plants, the limiting defect size in the vessels of the plants is no more than 10% of the wall thickness according to the results of statistical analysis. This finding makes it possible to increase the tolerable stresses by a factor of 1.6 compared to the current estimate of resistance to brittle fracture, which presumes the presence of a semielliptical surface crack of a depth corresponding to 25% of… Expand
