Abstract
The reactor core is carried from the base region of the primary vessel by a strongback. An annular foot is attached to the inside surface of the leak jacket leaving a clearance of 6 mm between the foot and the outer surface of the base region of the primary vessel. In the event of deflection of the primary vessel, downward displacement of the core relative to the control rods is limited thereby avoiding serious reactivity instability.
