FASTENER SHEARING TOOL

摘要

A tool is provided for separating a feeder coupling from an end-fitting of a CANDU-type nuclear reactor fuel channel by shearing one or more feeder coupling fasteners. A gripper has an inside surface and an outside surface. A portion of the inside surface is configured to engage a snout of the end fitting. A pusher is disposed about the gripper. The pusher has a nose portion for contact with the feeder coupling. An actuator controllably acts between the pusher and the gripper to drive the pusher into the feeder coupling to shear the feeder coupling fasteners.
