Abstract
Remote replacement of the ITER divertor will be required several
times during the life of ITER. To facilitate its regular exchange, the
divertor is assembled in the ITER vacuum vessel from 60 cassettes. Radial
movers transport each cassette along radial rails through the handling ports
and into the vessel where a toroidal mover lifts and transports the cassette
around a pair of toroidal rails. Once at its final position the cassette is
locked to the toroidal rails and is accurately aligned in both poloidal and
toroidal directions. A further requirement on the divertor is to minimise the
amount of activated waste to be sent to a repository. To this end the
cassettes have been designed to allow the remote replacement, in a hot cell,
of their plasma facing components. The paper describes the two facilities
built at ENEA Brasimone, Italy, whose aim is to demonstrate the reliable
remote maintenance of the divertor cassettes.
