ELECTRON IRRADIATION, TEMPERATURE, AND STRESS EFFECTON CORROSION OF Zr-, Ni-Cr-, AND Fe-Cr-BASED ALLOYS IN THE VICINITY OF THE WATER COOLANT SUPERCRITICAL TRANSITION
Year: 2020

Quantitative regularities of the Zr-1%Nb alloy, Ni-Cr alloy 690 and Fr-Cr stainless steel (SS) 12X18H10T corrosion in the near-critical domain (23.5 MPa, 360…380 °C) of a circulating water coolant are searched using multi-scale calculations of the NSC KIPT Super-Critical Water (SCW) Convection Loop experiment e-irradiation environment qualifiers. The per-sample quantification of irradiation doses, temperatures, stress, and the radiolytically altered coolant chemistry was obtained. A bi-linear in
