STRIP FOR A NUCLEAR FUEL ASSEMBLY SPACER GRID

摘要

The strip (16) is of the type comprising a wall portion (20) for delimiting a cell (18) for receiving a fuel rod (4) and allowing flow of a coolant upwardly through the spacer grid (14), a spring (22) provided on the wall portion (20) for biasing a fuel rod (4) extending through the cell (18) away from the wall portion (20), the spring (22) being cut out in the strip (16) and delimited by a slot (40) and a motion limiter (34) formed in the strip (16) on the wall portion (20) to limit motion of a fuel rod (4) received in the cell (18) towards the wall portion (20) against action of the spring (22). According to one aspect of the invention, the motion limiter (34) is located on an edge (54) of the slot (40) opposite the spring (22) and defines a risen portion (56) on said edge (54).
