The EU advanced lead lithium blanket concept using SiC sub f /SiC flow channel inserts as electrical and thermal insulators

The A-DC blanket concept with a self-cooled lead-lithium breeding zone and helium cooled steel structure is based on the use of oxide dispersion-strengthened (ODS) steel as first wall material and SiC/SiC flow channel inserts as electrical and thermal insulators. SPreparatory work on the EU advanced dual coolant (A-DC) blanket concept using SiC sub f /SiC flow channel inserts as electrical and thermal insulators has been carried out at the Forschungszentrum Karlsruhe in co-operation with CEA (SiC sub f /SiC composite-related issues) as a conceptual design proposal to the EU fusion power plant study planned to be launched in 2001 within the framework of the EU fusion programme having the main objective of specifying the characteristics of an attractive and viable commercial D-T fusion power plant. The basic principles and the study method for the A-DC blanket concept are presented in this report. The results of this study show that the A-DC blanket concept has a high potential for further development due to its high thermal efficiency and its simple concept solution.
