High Radiation Resistant Television System KTR-001 for Visual Inspections in Nuclear Reactors

The television system of increased radiation resistance KTR-001 is designed for visual inspection of products and structural elements of the core of nuclear reactors, forms video images at significant doses of gamma radiation, acceptable for television cameras based on solid-state matrices and is a closed-circuit installation. The transmitting side (TS) is located in the radiation exposure zone, performs light-to-signal conversion and pre-processes the video signal. Receiving side (RS) from the equipment room, outside the radiation exposure zone, performs final video signal processing and forms signals of communication interfaces.RS and RS are connected by a cable communication line.The system provides control of: iris, focusing, autoexposure, threefold zoom, illuminator, pointing of the transmitting part, switching of monochrome and colour image modes, dynamic shooting mode.
