This patent describes a top end support for rod guides disposed in closely spaced, parallel axial relationship in an inner barrel assembly of a pressurized water reactor vessel. The inner barrel assembly occupies a central portion of the vessel and is of a vertical height extending from a first plate of lower elevation to a second plate of higher elevation within the vessel. Each of the rod guides has a thin sidewall portion of elongated configuration and of an axial length corresponding substantially to the vertical height of the inner barrel assembly and having a generally square cross-section. Each rod guide accommodating in axial, sliding relationship therewithin a respectively associated cluster of elongated rods interconnected to extend in parallel axial relationship.
