Abstract
Apparatus for positioning a mast for the inspection and/or repair of a core shroud of a water-cooled nuclear reactor, heretofore have had television cameras directed at centering pins and bores from the side. Due to the inclined direction of surveillance, the alignment produced therewith has been inaccurate. In order to achieve a precise positioning, according to the invention a marking element which is provided between the television camera and the support plate has markings which can be brought into alignment with a marking made on the support plate. The centering pins and the bores are disposed concentrically to one another once they have been brought into alignment.
