Abstract:
PROBLEM TO BE SOLVED: To reduce the number of loading bodies of a nuclear fuel assembly, without changing greatly a conventional boiling-water reactor in which a core inlet coolant is unsaturated water.SOLUTION: The plane surface of a core comprising a nuclear fuel assembly 30 composed of many bodies is arranged in a square shape, to thereby obtain a square-shaped core. The nuclear fuel assembly 30 on a core center part of the square-shaped core is substituted for a moderator aggregate 101. The moderator aggregate 101 is loaded on the periphery of the square-shaped core, and a modified square-shaped core is formed, in which a neutron absorber 102 is loaded on the periphery of the moderator aggregate 101 loaded on the periphery.SELECTED DRAWING: Figure 6
