Description
A set of component material for PHWR RPV, including the largest forgings ever manufacture so far such as flanges (8,440 mm O.D.), shells and torus (7,960 mm O.D.) and dome (6,800 mm dia. in chord, 460 mm thick), was presented in the outline of manufacturing and properties. Even with increased dimensions and weight than the current largest forgings, the manufacture and the qualities achieved were satisfactory. These results encourage us in further developing PWRs and PHWRs with increased capacity. (orig.)
