Abstract: PURPOSE:To achieve higher safety when a control rod drops by itself by keeping the degree of concentration of a full length fuel rod at the outermost circumference position of a fuel assembly adjacent to the position of a partial-length fuel rod lower previously to reduce a local peaking at a low temperature. CONSTITUTION:The degree of concentration of full UO2 fuel rods 2 and 3 (Omark) is kept lower at the outermost circumference position of a fuel assembly adjacent to the positions of partial-length fuel rods P with a less axial length. Especially, the degrees of concentration of the fuel rods 2 at positions (1.5) with a left lower corner as origin and Gd fuel rods G at positions symmetrical thereto are lowered. With such an arrangement, an LPF at a low temperature, can be lowered by about 3% down to 1.36 under the same conditions of the average degree of concentration, the number of Dd fuel rods, the number of types in the degree of concentration. The lowering of the degrees of concentration of the fuel rods 3 at the positions (1, 2) and (1, 8) adjacent to the positions of the fuel rods P lead to a reduction in effects from water at the position where the fuel rods P are omitted and from water areas between the fuel assemblies.
