Abstract
The divertor area of ITER vacuum vessel consists of 54 modular cassettes
which must be exchanged after every 3–4 years of plasma operations.
Divertor Cassettes are locked in the vacuum vessel by means of
compressing them against the rails mounted in the inner and outer walls
of the vacuum vessel. According to ITER reference cassette locking
system, a Divertor Cassette has to be preloaded with a compression force
of 360 kN against the vacuum vessel rails. The preloading of the
cassettes is carried out with a hydraulic jack tool which is fitted into
the cassette body. The Jack will transmit a hydraulic force by pushing
the cassette latches against the outer rails, transmitting therefore the
required preloading compression force to the cassette. This paper deals
with the validation of Divertor Cassette locking system and it also
describes the design and testing of a radiation-hard, water hydraulic
jack. The validation of Divertor Cassette locking system has been the
first Divertor Maintenance operation tested at Divertor Test Platform 2.
