Development of Mono-bloc Forging for CAP1400 Reactor Pressure Vessel

摘要：

　　With the Development of Larger Output and Longer Plant Life for Advanced Pressurized Water Reactor Pressure Vessel(APWRPV),Larger and Mono-bloc Forgings must be Necessary.In the researching and manufacturing of CAP1400RPV forgings,China First Heavy Industries(CFHI)Manufactured Mono-bloc Upper Head with Quick-loc and Mono-bloc Lower Head(Combined Part of Transition Ring and Lower Head),reducing the welding process and the mechanical property deference comparing with the traditional manufacturing,Comparing with AP1000 forgings,not only Obtained better Mechanical Properties,but also Reduced Manufacturing cycle of RPV and Nondestructive in-service Inspection due to Elimination of Weld Seams.CHFI will Development Mono-bloc Nozzle Shell(Combined Part of Vessel Flange、Nozzle Shell and Inlet/Outlet Nozzles)for Future APWRPV.
