Creators

Description

A guide tube flow restrictor for use on an upper guide tube housing support plate of a nuclear reactor, for guiding of a control rod drive shaft through an aperture in the support plate and restriction of flow of coolant therethrough, has an outer ring seatable on the support plate, the outer ring having a flange member on which a plurality of flexible members are mounted, the flexible members having inwardly disposed deflectors thereon, and extending through the bore of the outer ring and the aperture of the support plate. An axially insertable sleeve, contacts the deflectors of the flexible members to radially force the flexible members outwardly into engagement with the walls of the aperture of the support plate.
