Abstract: For a long time now, bimetallic welds (BMWs) have been a necessity within the pressurized water reactors (PWR) and boiling water reactor (BWR) designs, where the heavy section low alloy steel components are usually connected to stainless steel (SS) primary piping systems. For PWRs, the BMWs, which are of particular interest, are those attaching the systems to the various nozzles of the reactor pressure vessel (RPV), steam generators (SG) and pressuriser. The scope of this paper is to study of mechanical behavior in bimetallic welds used in nuclear power plant. We intended to summarize the understanding of weld behavior that may be applicable in the design of welded components for nuclear power plant systems.
