Structural engineering problems in fintor conceptual designs

Conceptual design studies of a Demonstration Fusion Power Reactor are in progress at the JRC-Ispra, in collaboration with the CNEN-Laboratory of Frascati and the Electro-Technical Institute of the University of Naples (FINTOR-Group). The aim of these studies is to define the main features of a Tokamak-type fusion power reactor, demonstrating the feasibility of all technologies required for a prototype commercial reactor. The paper describes some of the results on: a) Structural stability of the outer containment vessel, b) stress analysis of the central magnet support, c) blanket thermal-mechanical behaviour. (orig.)
