In order to develop a compact intermediate heat exchanger which is applicable for high temperatures above 900degC, assuming HTGR (high temperature gas cooled reactor), a heat exchanger module made of SiCf/SiC composite has been designed, fabricated and tested with LiPb-He double loop. The heat transfer from liquid metal to gas has been measured, and heat transfer of >1.3 kW and reasonable heat exc...Show More
A high temperature lithium-lead blanket, which can be made within a limited extrapolations of present technology, has been proposed. The blanket structure is based on F82H as vessel material, and Pb-17Li as breeder. SiCf/SiC cooling panel is inserted between them to achieve high temperature extraction of Pb-17Li while maintaining F82H under allowable temperature limit. Neutronic analysis using ANI...Show More
Hydrogen deserves of a future energy medium in terms of global environmental issues and fossil resource constraints. This study intends to examine the feasibility of hydrogen production process by nuclear fusion heat. This process potentially provides hydrogen at significantly better efficiency than other proposed reaction such as electrolysis from renewable source with little CO2 emission, and is...Show More
