Abstract

PURPOSE: To obtain the fuel assembly with a large one in the thermal allowance, in a nuclear fuel assembly lined up and supported a plurality of nuclear fuel rod in a grid shape by spacers, by menas of setting up a plurality of fuel rods having a low output part near at the underside of the spacer.
CONSTITUTION: In a nuclear fuel assembly 10 composed by means of bundling a plurality of nuclear fuel rods 1 into a grid shape by spacers 2, U pellets 3 of a lower concentration than the concentrated U pellets 4 of another part of the fuel rod are arranged near at the underside of the spacers 2. By such means, the parts of a low concentrated U pellet 3 of the underpart of the spacers 2 become to a low output, and from the seeing the mean output distribution of the fuel assembly 10, low output parts are appeared near at the spacers 2, and from the result, the thermal allowance from a burnout point is present near at the spacers 2 position, and it can be enlarged than the conventional method.
