PREPARATION FOR D-T PHASE OPERATION IN JET
When tritium is introduced into the JET plasma the tokamak and its surroundings will very quickly become so active that all maintenance must be done by remotely controlled machines. Much of the major robotics equipment, to carry machine components and to place motorised tools in position to carry out fitting tasks, has now been constructed and is being commissioned with its control systems. The development of a variety of special-purpose tools is well advanced: they will be used to install equipment in the torus during the shutdown scheduled to begin in December 1986. Beryllium will be introduced into the torus in 1987. Because it is harmful when inhaled, equipment has been designed and procured to control the entry of men in air- line suits and the passage of materials. Because of the high cost of buying and then disposing of tritium, a clean-up and isotope separation plant is being designed and developed to re-process the gases exhausted from the torus and neutral beam injectors.
