Experimental results using the JET Real Time Power Control system

Publisher Summary The remote maintenance of a tokamak type fusion experiment requires a system to satisfy unscheduled repair after failure, scheduled replacement of parts due to consumable depletion or erosion and modification of the tokamak in accordance with experimental requirements. The preparation of remote handling equipment includes the design and manufacture of new equipment, proving of equipment reliability, development and proving of operating procedures, training of operators and setting up an operations support system. The remote handling system is required to be prepared in a time frame dictated by the lead time of the components to be handled. The remote handling philosophy has a direct influence on the design of remote handling equipment, the design of tokamak components, and the remote handling operations. The principle of component handling using teleoperation is characterised as the man-in-the-loop. The handling task is performed by an operator using a manipulator which provides force, and visual and audio feedback of sufficient resolution to create the atmosphere for the operator of actually being in the task environment.
