This patent describes a refueling machine comprising a trolley, movable within a horizontal plane above fuel assemblies in a reactor core of a nuclear reactor facility, an outer, stationary mast fixedly mounted to the trolley and extending vertically downwardly therefrom, and an inter mast coaxially mounted within the outer mast and telescopically movable therein. A gripper assembly is fixedly secured to the lower end of the inner mast for attachment to the fuel assemblies for movement of the fuel assemblies into the outer mast and in and out of the reactor core. A basket-type framework surrounds the lower end of the stationary mast and vertically mounted television cameras are fixedly attached to the basket-type framework with their lenses oriented vertically downwardly. Light sources are fixedly attached to the basket-type framework below the television cameras and support cables are secured to the basket-type framework for moving the basket-type framework vertically relative to the stationary mast.
