摘要：

New version of the local approach to fracture is presented. Within the framework of this approach a new methodology is developed, which provides prediction of radiation life time of a reactor pressure vessel not by ultimate shift of the Charpy critical temperature, Delta T-K, or by reference temperature, Delta T-0, but by the condition of brittle fracture initiation of irradiated metal ahead of a crack tip in reactor pressure vessels.
