Operational Experience from the JET Remote Handling Tile Exchange

The first fully remote handling operations on a fusion Tokamak have been completed at JET. The JET MKIIA Divertor has been successfully removed and replaced with the MKII Gas Box Divertor configuration using only remote handling methods inside the JET torus [1].The remote maintenance and modification of components at JET were undertaken using a man-in-the-loop approach, where the operator was provided with both visual and tactile feedback from a two arm servo-manipulator positioned inside the torus by an articulated boom. Using this methodology the operator was provided with a sense of presence inside the torus and therefore able to perform a wide range of tasks in the same way as if he himself were inside the torus.The operational experience gained from this first ever fully remote handling operation at JET has revealed the value of making detailed preparations and having a system flexible enough to accommodate a range of unplanned tasks. This paper describes the experiences from the setting up and subsequent managing of the remote handling operations.
