Description
This study is a part of the structural activity being conducted in the framework of the structural design of a DEMO Divertor. The thermal and structural analysis has already been started since a year and the first results has been partly published in a previous paper. The Cassette Body is being analyzed considering the most critical types of loads (e.g. coolant pressure, volumetric neutron heating and EM loads) according to their latest estimates.This work is based on the design-by-analysis approach adopted in the conceptual design study of the DEMO Divertor. The divertor design has been assessed in terms of a number of variables e.g. loads, key geometric dimensions, positions of the Cassette attachments to the vacuum vessel, or positions of load application, in order to enhance the knowledge about the structural behavior of the Divertor Cassette. In addition to the existing 3D solid element model, also a shell element model has been developed: so that an extensive parametric analysis can be easily done for a comparative estimation. The structural assessment was done according to the Design and Construction Rules for Mechanical Coomponents of Nuclear Installation (RCC-MRx).
