ABSTRACT:
In an assembly method for a nuclear fuel assembly, a grid member with springs and a grid member with dimples of the grid are arranged face to face such that grid cells of the grid member with springs and the grid member with dimples communicate with each other. Fuel rods are inserted into the grid cells of the respective grid members while the springs and the dimples are shifted sufficiently relative to each other so as not to contact the fuel rods. Subsequently, the grid members are moved to align the respective grid cells whereby the fuel rods are clamped by contacting with the dimples and springs. The grid members are then connected to each other.
