Tritium recovery from liquid Li17Pb83 alloy blanket material

Abstract Two methods to recover the tritium from the Li 17 Pb 83 liquid breeder used in the breeding blanket design developed at JRC-Ispra for INTOR/NET [1] are outlined and discussed. They are (i) direct tritium pumping from stagnant and stirred breeder, and (ii) tritium extraction from a packed or bubble column by flushing an inert gas in counter-current to the breeder. The lack of experimental data on tritium solubility and diffusion and on other physico-chemical properties of Li 17 Pb 83 do not yet enable us to choose among the two schemes. However, at present the second appears more promising.
