ITER vacuum vessel: Design review and start of procurement process

摘要

The ITER vacuum vessel (W) is one of the most critical components in the ITER project. It is on the criticalrnpath in the construction schedule and it is also a safety important class component (SIC), providing the first confinement barrier.rnAs a result of reviews and the latest physics analyses, design requirements have been updated (e.g. ELM/VS coils) and a few design changes have to be implemented. This paper covers the updates of the VV vertical and horizontal EM load conditions during asymmetric VDEs, the design analysis of the ELM/VS coils and their interfaces to the W, the blanket manifold design and the preparation of the technical specification in preparation for the procurement arrangement to be signed.
