Gillett, J E; Garner, D C; Sherwood, D G

A flexible support structure is described for the upper ends of first and second pluralities of rod guides of respective first and second different types disposed as corresponding, interleaved first and second matrices thereof in parallel axial relationship within an inner barrel assembly of a pressurized water reactor vessel for receiving therein respective, corresponding first and second different types of rod clusters. The inner barrel assembly occupies a central portion of the vessel and being of a vertical height extending from a first plate of a lower elevation to a second plate of a higher elevation, each of the rod guides being of elongated configuration and of an axial length corresponding substantially to the vertical height of the inner barrel assembly and the first and second pluralities of rod guides being disposed in parallel axial relationship in an array of interleaved, respective first and second matrices with the bottom ends thereof affixed to the first plate and the top ends thereof disposed adjacent the second plate.
