On the basis of experimental studies of impact strength and fracture toughness of heat-resistant steels of the NPPs 1st circuit using standard, sub-sized and miniature specimens, the energy characteristics of fracture in the operating temperature range, in particular, the specific energy of brittle fracture at the level of 0.6 0.15 J/cm2, were determined on the lower shelf of the fracture energy temperature dependence and it was shown the influence of the specimens cut direction on them, what can lead to a significant change in the critical brittleness temperature Tk (by 10-30 °C). The obtained results of experimental and computational studies can be used to search for additional safety margins to assessment the life-time of reactor pressure vessels and NPPs equipment elements
