Strength analysis results for the RF “modified” option of the shielding block for ITER blanket module

In accordance with the combined analysis of “reference” shield block (SB) design option the RF specialist have adopted the decision to develop the “modified” one. The present article contains the results of strength analysis for “modified” shield block design developed by the RF Domestic Agency. This stage of analysis is devoted to strength analysis of “lid-SB”-welded joint for elastic and elasto-plastic approach. There two welding types have been considered: electron beam welding (EB-welding) and thermal welding in inert gas (TIG-welding). These results together with the technological R&D will be useful for final decision on the shield block manufacturing technology.
