Design progress of the ITER divertor cassette-to-vacuum vessel locking system

Recent progress of the ITER divertor cassette-to-vacuum vessel locking system design and analyses is presented. The detailed thermal and non-linear static and dynamic stress finite element analysis have been performed to validate all design modifications of the locking system. These modifications have been driven mainly by remote handling requirements and reliability of locking system at action of various operational thermal and electromagnetic loads applied on divertor cassette.
