Abstract

Abstract

Tests for all 8 irradiation capsules of unit 1＆2 of QinshanⅡNPP were finished. Variation of strength, elongation and impact toughness of RPV steels with different fast neutron fluence was acquired. Upper shelf energy and ductile-to-brittle transition temperature（DBTT） shift were evaluated. Compared with non-irradiated materials, irradiation embrittlement effects were found in all specimens in irradiation capsules. DBTT shifts were lower than predicted value by FIS formula. Results showed that embrittlement effect of RPV steels for both units was relatively in low range.
