摘要： A reactor head inspection system for use in performing a non-destructive inspection of tubular components mounted on an interior surface of a reactor head is disclosed. The inspection system includes a movable carriage assembly including a elevation arm and an inspection device mounted at a distal end of the elevation arm. The inspection device includes a C- or U-shaped collar having an interior surface of sufficient interior dimension to enable positioning of the interior surface of the collar in close proximity of an exterior surface of a tubular component and also includes a magnetic and/or eddy current sensor. A plurality of video cameras and light sources are also provided on a distal surface of the collar such that, when mounted on the elevation arm, the collar can be controllably positioned in close proximity adjacent a tubular component of the reactor head to achieve a 360° view and inspection of a surface of the tubular component.
