Claim:
An underwater charge coupled device (CCD) camera for visual testing of a reactor cooling system, comprising: a CCD camera; a casing having a supporter therein to support the CCD camera and a cooling pin formed on a top surface of the casing; a Pb-glass window installed on a front side of the casing to shield the CCD camera from radiation and to reduce temperature difference between interior and exterior of the casing; a sealing O-ring preventing a coolant from being introduced into a gap between the Pb-glass window and the casing; a sealing nut providing a fastening force to bring the Pb-glass window into close contact with the sealing O-ring such that the Pb-glass window is sealed by the sealing O-ring; a rear cap disposed at the rear of the casing; a silicon O-ring preventing the coolant from being introduced into a gap between the rear cap and the casing; and a fastening nut providing a fastening force to prevent leakage between a camera cable and the casing.
