摘要

This paper reviews the design and performance of the in-vessel components of ITER as developed forrnthe EDA Final Design Report (FDR). The double-wall vessel is the first confinement boundary and is designedrnto maintain its integrity under all normal and off-normal conditions, e.g., the most intense VDE’s and seismicrnevents. The shielding blanket consists of modules connected to a toroidal backplate by flexible connectors whichrnallow differential displacements due to temperature differences. Breeding blanket modules replace the shieldrnmodules for the Enhanced Performance Phase. The divertor is based on a cassette structure which is convenientrnfor remote installation and removal. High heat flux (HHF) components are mechanically attached and can bernremoved and replaced in the hot cell. Operation of the divertor is based on achieving partially detached plasmarnconditions along and near the separatrix. Nominal heat loads of 5-10 MW/m~2 are expected and these arernaccommodated by HHF technology developed during the EDA. Disruptions and VDE’s can lead to melting ofrnthe first wall armour but no damage to the underlying structure. Stresses in the main structural componentsrnremain within allowables for all postulated disruption and seismic events.
