AbstractA new cassette concept based on a welded box structure made of stainless steel plates has been proposed for ITER FEAT. In this paper a summary of the analysis of the design is provided. Due to lack of space all the interesting multidiscipline items cannot be mentioned, but only the main results are presented. A complete report on the activity is in (Final report on Design of Welded Box Divertor Cassette ENEA Report FUS TN DI-NE-R-001, February 2001). The work, which has involved professionals coming from different institutes, shows that all the design requirements are fulfilled in normal operational conditions. The halo currents induce deformations close to the allowable limits. Therefore, some reinforcement of the cassette or some modifications of the attachment system to the Vacuum Vessel (VV) will be studied in the future design activities to reduce the displacement.
