摘要：
The Fukushima tragedy has initiated rising activities to remove a number of NPPs from operation all over the world. An aggressive hydrogen environment influence is supposed to accelerate a precipitateness of the fatigue fracture process in the considered NPP structure components. Consequently, technical risk and means for defrayment of this risk (in other words, means for NPP safety operation) will increase. It is possible to optimize these means using developed special engineering models of crack propagation in structure components subjected to aggressive hydrogen environment and cycling.
