description	PROBLEM TO BE SOLVED: To provide a nondestructive inspection apparatus capable of inspecting a component positioned in an annular gap inside a reactor pressure vessel. SOLUTION: A main body 19 of the nondestructive inspection apparatus is positioned on a spray line header 13, connected to a thermal sleeve 16 within a cooling water inlet nozzle 12, and fixed to a core spray line 14 by vertically clamping the core spray line 14 of the header 13 with fixing units 21a, 21b, at a position where the thermal sleeve 16 to be inspected is located. Scanners 24a, 24b insert a tape probe 27, having an inspection head 28 inside the annular gap 17 formed between a wall surface of the thermal sleeve 16 and a wall surface of the cooling water inlet nozzle 12 in an axial direction. The scanners 24a, 24b are guided by guide rails 22a, 22b and are moved in the circumferential direction of the annular gap 17 so that the inspection head 28 moves in the circumferential direction of the annular gap 17.
