正する。Amendment September 22, 1983 The brief description of the drawing is amended as follows. In the 8th line from the bottom of page 7 of the specification, "This is a view in the direction of the arrow." is replaced with "A view in the direction of the arrow." Figure 4 is an illustration of a conventional nuclear fuel assembly. This is an explanatory diagram of the configuration of fuel rods in a nuclear fuel assembly.''
