The Joint European Torus (JET) project was set up under the auspices of EURATOM in the late 1970's in order to study the feasibility of controlled nuclear fusion. The experimental device has been operating since 1984 and comprises a toroidal shaped vacuum vessel in which high temperature plasma is created and controlled. During September and October 1997 a series of experiments was performed in the JET machine using a deuterium-tritium (D-T) mixture, the fuel to be used in future fusion reactors.

The JET remote handling equipment was originally specified, designed, built and commissioned to satisfy a general repair and maintenance function. The experimental nature of the JET machine and its progressive modification and development demanded that the remote handling system be as adaptable as possible and be able to undertake repair and maintenance tasks at short notice. To meet this requirement a fully teleoperational methodology was adopted and a system based on man-in-the-loop control using bi-lateral, anthropomorphic, force reflecting servomanipulators has been implemented.

A major modification to the JET torus using only remote handling methods is now required and, although a significant departure from the original requirements, the adaptability of the original remote handling system has allowed it to be applied to this new task with minimum modification. This paper describes the preparations being made for this first fully remote handling shutdown for JET. ET.
