Description
Summary:For fusion energy realization, attractive energy conversion system and fuel supply system are essentially required. The current ITER test blanket module study has dual coolant lithium lead (DCLL) system as the attractive blanket option. The concept of making ceramic thermal insulation panels for DCLL blanket has been presented, however, realistic material systems have not been proven so far. This work is trying to present the porous SiC/SiC thermal insulation panel based on the current NITE-method technology. Typical panels with through thickness and in-plane channels and porosities tailored were designed, fabricated and evaluated, successfully. Thermal conductivity of those panels were controlled, as designed, and the tailoring capability of thermal conductivity by NITE-method was presented. This concept and technology can satisfy the basic material requirements as well as economical requirements and large scale production requirements.
