After Tritium is introduced into the JET vessel, the activation levels will be such as to preculde- man-entry into the Torus Hall. The remote maintenance equipment described herein has been devised over the last several years in order to be able to continue operation of the facility in the event of all but major machine failures. Computer assisted positioning of force-feedback servo manipulators to all parts of the JET machine is effected by 2 transporters, one complete and the other in the design phase. Special cutting, positioning and welding tools have been procured to carry out specific tasks in areas of limited access.
