Structural materials selection for the sodium-cooled reactor plant steam generator

Abstract

Steels and alloys of various structural classes are considered from the point of view of the required level of service characteristics necessary for the safe operation and manufacture of a sodium-cooled reactor plant steam generator. After the analysis, it was found that the optimal structural material for the steam generator of a high-power reactor plant with a sodium coolant is martensitic stainless steel with a chromium content of 12 wt.%.
