Abstract: 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.
