ABSTRACT:
A method and an apparatus for restraining a cracked shroud against vertical joint separation. The method involves the placement of a plurality of tie rods (e.g., four) in the downcomer annulus at respective azimuthal positions, each of the tie rods having one end anchored to the shroud support plate. The other end of each tie rod is latched over the top edge of the shroud to counteract lifting forces exerted on the shroud by the bolts which hold down the shroud head.
