Preliminary Design of a Heat Pipe-Cooled Blanket for CFETR

Blankets are a difficult problem for fusion engineering design. Because of the complex flow channels, design, production, processing, and accident maintenance blankets all huge challenges traditional water/gas-cooled blankets. bridge heat transfer tritium production. A high-performance blanket with simplified structure is obviously beneficial engineering, safety, economy. In this study, gravity pipes instead coolant channels adopted to remove heat. Compared coolant-cooled systems, may be simpler more reliable. The in-vessel in-box loss (LOCA) will not occur because there no in blanket. Moreover, damaged pipe replaced easily compared water-cooled hypothetical pipe-cooled China Fusion Engineering Test Reactor (CFETR) was proposed one module analyzed by numerical simulation. results were those blanket, temperature distribution uniform. This study verified preliminary feasibility provided fresh idea
