OVERVIEW OF EU ACTIVITIES ON DEMO LIQUID-METAL BREEDER BLANKETS

The present paper gives an overview of both design and experimental ac tivities within the European Union (EU) concerning the development of liquid metal breeder blankets for DEMO. After several years of studies on breeding blankets, two blanket concepts are presently considered, both using the eutectic Pb-17Li: the dual-coolant concept and the wate r-cooled concept. The analysis of such concepts has permitted the iden tification of the experimental areas where further data are required. Tritium control and MHD issues are, at present, the activities to whic h is devoted the greatest effort within the EU.
