合体の支持格子。 A lattice plate is inserted through and attached to the intersection, and the upper corner frame and lower corner frame are used for passing each fuel rod in three of the four adjacent cells and the moderator in the remaining one cell. Each wide side band leaf spring with a V-shaped center elastic support part and a narrow side band plate spring with a W-shaped center elastic support part are connected in series to each other to hold the hollow tubes thicker than the fuel rods. Regarding the box-shaped spring for the cell corner part, the latter, the narrow side strip leaf spring, is a boiling type formed by making the leaf width at the upper and lower leaf spring ends wider than the leaf width at other parts. Support grid for water nuclear fuel assembly.
