A supporting member for an array of parallel rails each carrying one row of slidably mounted pins of a fuel clister is placed coaxially at the lower end of a vertical fuel assembly wrapper. The ends of the rails are engaged in vertical slots formed in the supporting member and are secured by locking-rods mounted in open grooves located transversely to the slots in the outer faces of the supporting member.

Device for supporting a fuel-pin cluster within a nuclear reactor fuel

A supporting member for an array of parallel rails each carrying one row of slidably mounted pins of a fuel cluster is placed coaxially at the lower end of a vertical fuel assembly wrapper. Each parallel rail is provided at each end with a downward extension and terminal lug which engages in a lateral groove formed in the periphery of the supporting member in order to lock and maintain the rails and the fuel pins in uniformly spaced relation within the fuel assembly wrapper.
