Abstract
The spacer grid for a nuclear reactor fuel assembly has an open structure constituted by an array of flat sheet metal members in interfitting relation and defining compartments. Narrow corrugated strips project into the interior of the compartments and form separations between openings of substantial width in the surface of the sheet metal members and an outer frame surrounds the structure. The sheet metal members are joined to the corrugated strips by means of a zone having lower mechanical strength so as to increase the deflection of each strip in respect of the same applied force.
