Abstract
Method of producing a core baffle with a plurality of horizontally disposed, parallel profile-rib rings for enclosing the fuel assemblies of a pressurized-water reactor, the profile-rib rings being formed with respective cutouts having a polygonal contour corresponding to that of the reactor core and with baffle plates secured vertically to the profile-rib rings and forming a casing matching the contours of the cutouts, which includes fastening to the profile-rib rings, by welding, one end of a plurality of ribs having a height corresponding to a mutual spacing of the profile-rib rings; successively welding the profile-rib rings to one another by the respective ribs thereof into a cage; assembling baffle plates bent partly into profile sections into the form of casing by bracing the plates against the cage; successively welding the baffle plates to the profile-rib rings of the cage; and welding the baffle plates to one another into a tight casing.
