END FITTING ASSEMBLY FOR NUCLEAR REACTOR MOCK-UP ASSEMBLY

摘要

A modular end fitting assembly for use with a mock-up assembly for simulating nuclear reactor end fitting conditions. A main tube portion has an end fitting hub and an end closure fitting is removably secured thereto in axial relation by a securing mechanism. The tube has at opposing ends an outboard end portion and an inboard end portion. A locating aperture passes through the inboard portion for fixing tube length in the mock-up. The outboard portion has a feeder mount radially positioned thereon relative the aperture. The mount has a predetermined angular orientation relative the fitting when the aperture fixes the length of the tube. Alternatively, the mount is positioned inboard and adjacent the hub, which has an outboard end surface. The fitting has an inboard surface for releasably securing the fitting with the hub at a predetermined angular orientation relative to the position of the mount and tube.
