[2L14] Compatibility between Fusion Reactor Blanket Structural Material F82H and Solid Breeder Lithium Oxide

*Keiji Oishi1, Takayuki Terai1 (1. Univ. of Tokyo)

Keywords: solid breeder blanket, F82H, lithium oxide, corrosion, diffusion coefficient

Compatibility experiments between F82H and Li2O were carried out by contacting their specimens directly in He +0.1% H2 sweep gas at 400, 600 and 800 C for 100-3000 hr. After each experiment, the O diffusion distance was actually measured from the SEM / EDX image, and the corrosion depth of F82H in the blanket condition was estimated.
