STUDY ON MATERIAL SELECTION OF REACTOR PRESSURE VESSEL OF SCWR
This paper first analyzes the feasibility of SA-508 Grade 3 Class 1 Steel as an alternative material for Supercritical Water-Cooled Reactor(SCWR)Reactor Pressure Vessel(RPV).This kind of steel is limited to be applied in SCWR RPV due to its quenching property,though large forging could be accomplished by domestic manufacturers in forging aspect.Therefore,steels with higher strength and better quenching property are needed for SWCR RPV.The chemical component of SA-508 Gr.3 Cl.2 steel is similar to that of SA-508 Gr.3 Cl.1 steel,and more appropriate matching of strength and toughness could be achieved by the adjusting the elements contents,as well as proper control of tempering temperature and time.In light of the fact that Cl.2 steel has been successfully applied to steam generator,it could be an alternative material for SWCR RPV.SA-508 Gr.4N steel with high strength and good toughness is another alternative material for SCWR RPV.But large amount of research work before application is still needed for the lack of data on welding and irradiation etc.
