operation floor, and capable of executing at relatively low operation cost. SOLUTION:
The core shroud has an upper ring 3, an upper shell 4, a middle ring 5, a middle shell 7, a lower ring 8 and a lower shell 9 from the top, forms a coolant flow path in a reactor pressure vessel, and supports an upper grid plate 6 for supporting the upper end part of the fuel assemblies with the middle ring. On the other hand, a core support plate for supporting lower end part of a fuel assembly is supported with a lower ring. In this case, it is structured in two split configuration of an upper half shroud 1 constituted integrally with the upper ring, the upper shell and the middle ring, and a lower half shroud 2 constituted integrally with the middle shell, the lower ring and the lower shell, and in the constitution that the upper half should and the lower half shroud are fixed tight.
