Researches for a Decommissioning Device Development Concept of the Horizontal Fuel Channel in the CANDU 6 Nuclear Reactor: Presentation, Functioning and Operating

This paper present a possible method for decommissioning of the horizontal fuel channels in the CANDU 6 nuclear reactor, a new device design concept solution with an operating panel. The device shall be designed according to the radiation protection procedures. The horizontal fuel channels decommissioning device from the CANDU 6 nuclear reactor is an electromechanical system with many freedom degrees, able to perform the internal components extraction and manage the storage into the waste container. The operations are performed under the control of a system equipped with a Programmable Logic Controller (PLC) and monitored by an operator panel, Human Machine Interface (HMI) type. The fuel channel decommissioning device ensures full radiation protection of workers and environment during the dismantling stages.
