Abstract:
A nuclear reactor having an upper internals control rod assembly guide tube formed from upper and lower sections that are connected along a central axial region of the guide tube at an intermediate coupling. An extended control rod axial support is provided for at least some of the control rods over a finite distance within at least one of the interiors of the lower guide tube section or the upper guide tube section.

Claim (Index 1):
A nuclear reactor including a pressure vessel housing a core of fissile material and an upper core plate substantially covering the core, a control rod guide tube having an extended axial length, for guiding a control rod assembly comprising a plurality of individual control rods, into and out of the core, the control rod guide tube extending between the upper core plate and an upper support plate supported above the upper core plate, the control rod guide tube comprising:\n a lower guide tube section connected at a first end to the upper core plate and terminating at a second end at a rigid intermediate coupling; an upper guide tube section connected at a first end portion to the upper support plate and terminating at a second end at the rigid intermediate coupling; and an extended control rod guide assembly supported substantially at the rigid intermediate coupling and extending axially, a finite distance into at least one of an interior of the lower guide tube section or the upper guide tube section, the extended control rod guide assembly being configured to provide support for the plurality of individual control rods, wherein the finite distance is substantially less than the extended axial length of the control rod guide tube.
