Fusion Engineering and Design, 2013•ElsevierLiquid lithium has been one of the candidates of the tritium breeder and possibly a coolant
for the blanket of fusion reactors. The observation of corrosion behavior was conducted on
the bellows of the bellow-sealed valve used in a lithium circulation loop at 350–500° C for
about 1500h. The results were obtained from observation of the surfaces and cross sections.
The bellows was found to be fractured and detached. Selective elements were depleted on
the surface.
