Structural integrity analysis for final design of ITER gas fueling manifold

The Gas Fueling (GF) manifold is a major subsystem of the ITER gas injection system and it is designed to deliver fueling gases from tritium plant for initiating, maintaining or controlling plasma. According to the load specifications, the detailed structural analysis of ITER GF manifold have been performed to assess the design and structural integrity. The results show that the GF manifold is safe under all load combinations and the structural integrity requirements are well satisfied. This paper provides briefly the results of structural analysis for ITER GF manifold final design review.
