Rod guide support structure of the inner barrel assembly of a pressurized water reactor.

摘要

A support structure for the upper ends of rod guides disposed within an inner barrel assembly (24) of a pressurized water reactor vessel (10) and having their top ends connected to top support plates (52) having mating interior and exterior vertices for assembling said top support plates (52) and a plurality of vibration arrestors (140; 140') associated with said top plates (36) for resiliently opposing any reduction of the parallel spacing and lateral loads tending to displace the top plates (36).
