Inside the square frame, a large number of cells are arranged vertically and horizontally, and a required spring is attached to each cell to supply fuel. In a spacer that elastically supports rods and water pipes, a fuel assembly is formed by bending inward the upper and lower corners of the feed side joint ends of each outer plate that form part of the corners of the square frame. spacer for.
