Simplified, flexible top end support for cantilever-mounted rod guides of a pressurized water reactor.

摘要

In a pressurized water nuclear reactor wherein a rod guide structure (52) is supported above the reactor core and has top support plates (36, 38) disposed on, and connected to its top ends adjacent top support plates (36, 38) having mating, exterior peripheral surfaces for assembly thereof in mating relationship, and said mating exterior peripheral surfaces further having vertically extending, recessed channels (117b) and transverse extensions (107) which are received in the vertically extending recessed channels (117b) in axially sliding relationship, and the top support plates (36, 38) being resiliently interconnected.
