A main bodyof the nondestructive inspection apparatus is positioned on a spray line headerconnected to a thermal sleevewithin a cooling water inlet nozzle, and fixed to a core spray lineby vertically clamping the core spray linewith fixing unitsat the position where the thermal sleeveto be inspected is located. Scannersinsert a tape probehaving an inspection headinside an annular gapformed between the thermal sleeveand the cooling water inlet nozzlein an axial direction. The scannersare guided by guide railsto move the tape proveso that the inspection headcan move in the circumferential direction of the annular gap
