Abstract (en)
[origin: EP0287422A1] The strut grid consists of circular hoops (1, 2) with a common axis arranged so as to define annular rows (5, 5') of roughly constant width. Supporting brackets (8) made from a metal sheet folded into a U shape are each welded to two successive hoops and provide for their assembly. The supporting brackets (8) also hold the tubes (4) which are engaged in an inner housing defined by the arms of the supporting brackets (8). Application especially to emergency heat exchangers in fast neutron nuclear reactors cooled by liquid sodium. <IMAGE>
