Rotary device designed to shear a tube bundle containing spent nuclear fuels

Description

The rotary device features the following: cutting systems rotating about a horizontal axis and driven by a motor; a magazine receiving the tube bundle, placed above the cutting system and capable of being suitably positioned in relation to the cutting system: the cutting system is integral with a rotor, itself driven by a low-speed high-torque motor; the rotor is isolated from the motor by means of gaskets and gas flow; the cutting system consists of a series of tube-cutting teeth placed in stages so that the bundle is attacked symmetrically at its outer edges
