Reactor pressure vessel video inspection system

The present invention discloses a nuclear reactor pressure vessel video inspection system, provided by the imaging system in an underwater nuclear reactor pressure vessel, the surface of the overlay within the pressure vessel, the connecting seam, the flange surface, the bottom support of the reactor the pressure vessel through the bottom member, foreign matter within a container inspection process for centralized output video signal recording and effective access-service reactor pressure vessel before the test data / in-service inspection, in order to analyze the state of the pressure vessel to provide a very important in accordance with. Further, the operating state of the underwater imaging system (e.g., system scaling underwater camera, zoom, light switch state), the operating position (recording angle), and the illumination brightness can be adjusted in real time, to meet the needs of different conditions to improve the effectiveness and accuracy of the work product.
