Safety design for ITER and fusion power reactors

摘要

The present paper outlines key design features of relevance for the safety of international thermonuclear experimental reactor (ITERE) and fusion devices of reactor scale. These features support the intrinsic safety characteristics of fusion. The most important safety function is the confinement of radioactivity. The first barrier is based on the vacuum vessel (VV) and its extensions. A pressure suppression system linits the maximum pressure of the VV in the event of loss of coolant.
