ABSTRACT:
A cylindrical shell or so-called reactor core basket is fitted with a coaxial and cylindrical bearing ring which is joined to a top flange of the core basket by means of radial struts and rests on an internal annular shoulder of the reactor vessel. Passageways between the bearing ring and the struts accommodate instruments for nondestructive testing of welded joints, the instruments being guided and displaced over the external face of the core basket in order to inspect the internal face of the reactor vessel without any need to remove reactor internals.
