Abstract

Remote replacement of the ITER divertor will be required several times during the life of ITER-FEAT because of failure, erosion of the armour or in order to install alternative divertor geometries. An R&D project was conceived during the ITER EDA to demonstrate the feasibility and the reliability of the divertor remote maintenance operations. Two test platforms have been set up and are being used to evaluate equipment and procedures, maintenance and refurbishment times, and rescue scenarios. Following a short description of the test facilities set up at ENEA, Brasimone, Italy, the paper reports on the results from the two platforms, which confirm the overall feasibility of the proposed maintenance and refurbishment schemes. The paper also describes the programme of work currently underway which is aimed at verifying the design changes made necessary by the move from the 1998 ITER design to the more compact ITER-FEAT design, and by design short-comings highlighted during the operation of the platforms.
