Description

In the framework of PA realization, specialists from NIKIET and Efremov Institute are developing a design of First Wall (FW) Full Scale Prototype (FSP) in order to demonstrate its manufacturability and qualify critical technological processes. Design of FW FSP is developed based on the FW 14 type A. The semi-prototype has been manufactured in order to verify the FW design. Based upon the manufacturing experience, some modifications have been implemented into FSP design in order to simplify assembly and manufacturing processes. Each FW includes plasma-facing components (FW fingers), FW beam, mechanical attachment system and electrical connection system with the shield block. All the FW fingers are attached to FW beam by two poloidal straight welds. In order to provide access of welding equipment, the 60 mm slot is performed on the FW front surface. The central slot insert (CSI) is implemented into FW design to protect central slot from plasma radiation. The fixation of CSI is provided by three ring welds and the hydraulic connection is provided by two pipes. The basic design of CSI has been modified in order to simplify manufacturing and final assembly. This paper presents results of thermal and structural analysis of modified FW design in particular CSI.
