“…It has been found that some deleterious elements may cause synergy effect in producing the complex radiation defects which can lead to the radiation--induced degradation in the mechanical properties of RPV steels [2]. The problem is rather complex and it is still the subject of large international programs [3][4][5]. In order to understand the role and influence of Ni, Si, Cr and Mn as alloying elements on the mechanical properties of steels, a large spectrum of ferritic steels with parametric variation of alloying elements, as well as impurities content, were designed.…”

In this paper we report preliminary results from a study focused on investigation of the role of elements as Cr, Ni, Mn and Si in the radiation stability of reactor pressure vessel steels. Twelve model ferritic steels and eight model welds with basic composition derived from Russian VVER-1000 and Western PWR reactor pressure vessel materials were studied by magnetic Barkhausen noise and Charpy-V impact measurements. Comparison of these two model materials led to the conclusion that the ductile-brittle transition temperatures and Barkhausen noise RMS values of model steels are shifted to the lower values as those of model welds. The VVER-1000 as reference point is shifted to lower RMS values in comparison with model steels and model welds. The next stage of the assessment will involve the investigation of the radiation effect on the model steels with accumulated neutron fluence of 10 19 n/cm 2 .
