Abstract
A restraint to enable temporary bracing and operation of a thermally cracked sparger nozzle mounted from a sparger manifold at the end of a pipe elbow is disclosed. The restraint includes a second and surrounding restraint elbow which is fitted over and captures the sparger elbow. The restraint elbow has a saddle surface baseplate communicated to the lower end which rest on the sparger manifold to form a substantially water tight base for the restraint. The nozzle end of the restraint elbow is fitted with a nozzle aperture plate for surrounding the outside of the sparger nozzle again in substantially water tight relation. The plate is mounted for movement on the end of the restraint elbow for conforming threading of the restraint at the plate over the sparger nozzle. The restraint can be rapidly mounted (in less than a minute), tack welded at the aperture and seat tensioning bold (in less than 4 minutes) and left in the reactor for a complete fuel cycle. With the restraint mounted, cracked and defective sparger nozzles are restrained in place while a replacement sparger is fabricated.
