SANS results of neutron-irradiated VVER-1000 RPV steels and model alloys

Ulbricht, A.; Bergner, F.

The aim of the present poster is to contribute small-angle neutron scattering (SANS) data to the experimental database of the integrated project PERFECT. The results serve as database for model validation. The nature of irradiation-induced features in Fe-3wt%Ni was investigated and compared with results for commercially pure Fe. We have observed a three times larger volume fraction of irradiation-induced scatterers for the Fe-Ni alloy than for pure Fe. For VVER-1000 RPV steels matrix damage is the dominant feature in the case of low Cu level, but Cu-rich precipitates significantly contribute for Cu-enriched steels.

Keywords: Small-angle neutron scattering; radiation defects; RPV steel; Fe-Ni alloy
