文摘

Structural elements in high Ni welds are studied at different irradiation fluxes. AES study demonstrated different P GB kinetics at different irradiation fluxes. Hardening and non-hardening mechanism contributions to the flux effect are assessed. Correlation between ΔTK and P and Ni GB content is shown for VVER-1000 RPV welds.
