ABSTRACT:
A tool which can be remotely operated to precisely measure the downcomer annulus width at the elevation of the top guide support ring. The measuring tool has a support frame adapted to be grappled and then hooked onto the upper rim of the shroud, and a measuring subassembly mounted on the support frame. The measuring subassembly has a contact block mounted on a bearing-mounted slider. The slider is translatable between a retracted (i.e., "home") position and an extended position in response to actuation of a cylinder mounted on the support frame. When the tool is properly installed on the rim of the shroud, the slider travels radially outward in response to actuation of the cylinder until the contact block abuts the opposing inner surface of the reactor pressure vessel wall, i.e., the slider is stopped. The measuring subassembly further includes a magnetic position transducer which produces electrical signals which are function of the distance traveled by the slider from the "home" position to the "stop" position.
