| Outline of Final Research Achievements |
Addition of 0.1 wt% Ti fine powder into molten salt coolants (FLiBe, FLiNaBe, FLiNaK) increased the effective hydrogen solubility by > 5 orders. The addition of Ti fine powder also suppressed hydrogen absorption into a vanadium alloy material immersed in a molten salt coolant. These experimental results indicate that the present new concept, i.e. active control of hydrogen solubility of molten salt coolants by addition of metal fine powders, enables safer and high-efficiency power generation with a molten salt cooled blanket system. In the present study, an idea of selective microwave heating of the metal fine powder in a molten salt coolant has newly been proposed for effective hydrogen recovery from the powder and successfully demonstrated.
