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.
摘要：针对ITER FEAT，提出了一种基于不锈钢板焊接箱形结构的新型盒体概念。本文对该设计进行了分析总结。由于篇幅所限，无法详述所有跨学科的有趣内容，仅呈现主要结果。相关活动的完整报告见《偏滤器盒体焊接箱形结构设计最终报告》（ENEA报告FUS DI-NE-TN-001，2001年2月）。该工作汇聚了来自不同机构的专业人员，结果表明，在正常运行条件下，所有设计要求均能得到满足。环向电流引起的变形接近允许极限。因此，在未来的设计活动中，将研究对盒体进行局部加固或对真空容器（VV）连接系统进行改进，以减小位移。
