Simplified, flexible top end support for cantilever-mounted rod guides of a pressurized water reactor
This patent describes a support for the top ends of a plurality of elongated rod guides of at least first and second types, generally vertically disposed within a pressurized water reactor vessel in corresponding, at least first and second interleaved matrices. The vessel has lower and upper support structures and the rod guides have lower ends fixedly supported on the lower support structure and upper ends disposed adjacent to and spaced vertically below the upper support. The support consists of: top support plates of at least first and second types, connected to the respective top ends of the corresponding, at least first and second types of rod guides; the top support plates of at least first and second types having respectively mating, exterior peripheral surfaces for assembly of each support plate of one type in mating relationship with respective, contiguous and surrounding top support plates of another type; the respective surfaces further comprising a vertically extending, recessed channel in one peripheral surface and a mating transverse extension in the mating peripheral surface; means for resiliently interconnecting each top support plate of one type with each of the respective, contiguous and surrounding top support plates of the other type; and the type being each top support plate of a selected adapted for connection to the upper support structure of a pressure vessel in which the elongated rod guides and respectively associated top support plates are disposed.
