•The design of FW panel with welded fingers has been developed.•The FW panel with welded fingers has been analyzed.•The pressure drop in FW panel coolant path do not exceed allowable one.•The mass flow rate distribution between finger pairs are on acceptable level.•Temperatures in FW components do not exceed allowable one.
According to Procurement Arrangement (PA) Russian Federation will procure 40% of enhanced heat flux first wall (FW) panels. The signing of PA is scheduled on November 2013. In framework of PA preparation the RF specialists perform EHF FW design optimization in order to provide the ability to operation of EHF FW panel under ITER conditions.This article contains the design description of EHF FW 14 developed by RF and following analysis have been performed:•Hydraulic analysis;•Transient thermal analysis;•Structural analysis.Analyses results show that new design of FW panel with two straight welds for finger fixation on FW beam developed by RF specialists can be used as a reference design for ITER blanket EHF FW panel loaded by 5 MW/m2 peak heat flux.
