摘要： A carriage is designed for transport into and out of a pipe, carrying appropriate lighting and a television camera with a lens cover movable from a remote location between covering and uncovering positions. A movable portion carrying two sets of three nozzles, one of each set being equipped to emit a spray of water, liquid penetrant and air, is mounted on the carriage. After an initial visual inspection on a remote TV monitor to verify location and check for the presence of relatively large cracks or flaws, the lens is covered, the inside pipe surface is sprayed first with water for cleaning, then with penetrant which enters any cracks which may be present, and again with water to wash away any penetrant other than that which has entered cracks in the area being inspected. The surface is then dried by the air nozzle, the lens cover removed and a "black light" source turned on, thus rendering visible on the TV monitor any liquid penetrant which is entrapped in small cracks or faults in the pipe. A radioactive substance may also be carried on the device and used for supplementary inspection by wrapping a photographic film on the exterior of the pipe.

摘要： A system for performing visual inspection through a television camera and monitor of submerged portions of nuclear reactors such as those used in electrical generating plants. A conventional camera and one or more lamps are mounted upon central portions of a positioning device. A pair of arms extend outwardly from opposite sides of the central portion, perpendicular to the camera axis, and a third arm extends to a terminal end above the central portion on a line preferably intersecting the center of gravity of the assembly and perpendicular to the camera axis. The positioning device, carrying the camera and lamp, is lowered into the reactor cavity by a line attached to the terminal end of the third arm, such line preferably comprising the electrical cable for the lamp and/or camera. A flexible line is attached to the end of each of the outwardly extending pair of arms. The inspection is performed by three individuals, two of whom stand at spaced locations on a platform or walk-way above the reactor cavity, one holding the line attached to the third arm and the other two lines attached to the pair of outwardly extending arms. The vertical position and rotational orientation of the positioning device are controlled by the individuals holding the corresponding lines as the third individual views the television monitor, directs the other two in manipulation of the positioning device and operates any necessary controls such as lamp intensity.
