Abstract
Abstract A plurality of vertical inner shell plates form an inner shell and are free of direct interconnections. A plurality of vertically spaced, horizontal section ribs are provided, each of which surrounds said shell. A plurality of vertical posts are connected to said ribs to form therewith a cage adapted to be inserted as a whole into said tank around said core. Each of said inner shell plates is firmly secured to only one of said section ribs and vertically movably guided on all other section ribs.
