1. An inspection apparatus for a penetration pipe formed at a nuclear reactor head, comprising:
a body; a probe module installed at the body and having a probe which is inserted in the penetration pipe to inspect damage of the penetration pipe; a fixing module installed either along a longitudinal direction of the body or on the same line as the probe module along the longitudinal direction of the body, and having either an expanding cylinder which is inserted in the penetration pipe to support an inner diameter of the penetration pipe or a cone support rotating gripper configured to support an outer diameter of the penetration piper or a cone; and a rotating module installed in the longitudinal direction of the body and having at least one selected from the group consisting of: (1) an expanding cylinder which is inserted in the penetration pipe to support the inner diameter of the penetration pipe, (2) an outer diameter support gripper configured to support an outer diameter of the penetration pipe, and (3) said cone support rotating gripper configured to support said outer diameter of said cone of the penetration pipe.
