Summary:—Having analyzed experimental data on the long-term strength of unirradiated austenitic materials and predictive dependences obtained in the context of a physical and mechanical model of intergranular fracture, the authors have determined the assurance factor for plotting the long-term strength curves for unirradiated and irradiated materials. The above model, as well as experimental results, has made it possible to calculate the normative curves for the initial and irradiated steels Kh18N9 and 08Kh16N11M3. Their validity has been verified on the basis of external and intrareactor tests.
