Abstract
An improved method of replacing at least a portion of a shroud apparatus of a BWR includes forming a cut in the shroud and removing at least a portion of the shroud apparatus that is adjacent the cut from a remaining portion of the shroud apparatus. The method also includes positioning a replacement shroud system adjacent the remaining portion of the original shroud apparatus and connecting a plurality of removable fastening devices between the new replacement shroud system and the remaining portion of the original shroud apparatus. The replacement shroud system thus can, in the future, be readily replaced by detaching the removable fastening devices, removing the replacement shroud system, and installing a new replacement shroud system with less effort than was required in cutting through the original shroud and replacing it with the replacement shroud system. An improved replacement shroud system is also disclosed.
