Outline of Final Research Achievements

Promising liquid blanket candidates of Li17Pb83 eutectic alloy and Flinabe molten salt were investigated along with Li for comparison and circulating loops for each candidate were made up. Constitution of integrated blanket systems and clarification of their operating conditions have been made from various viewpoints for effective simultaneous recovery of heat and tritium from each fluidized liquid blanket. Permeation window. liquid-bubbles direct contact tower and Y getter bed were experimentally investigated as examples for effective tritium recovery methods and designs of concrete recovery apparatus were presented. The design which satisfies the conditions not only to keep tritium inventory in the Li-Pb or Flinabe blanket as low as possible but also to suppress tritium permeation leak through tubes of their blankets or heat exchanger as low as reasonably achievable was clearly presented in international scientific journals in English.
