Potential design problems for ITER fusion device

Abstract The international thermonuclear experimental reactor (ITER) is a worldwide project currently being built in France for the demonstration of the feasibility of thermonuclear technologies for future realization of successful commercial fusion energy. ITER is of the tokamak based design using...

A key obstacle to such design is the performance during abnormal events including plasma disruptions and so-called edge-localized modes (ELMs).
