N2 - Tritium sorption capacity is an important parameter to evaluate tritium behavior on lithium ceramic breeder materials. In the present study, sorption and desorption behavior of tritiated water on Li2TiO3 with additional Li, which is in a developmental stage in Japan Atomic Energy Agency as an advanced tritium breeder materials, was observed at 20, 300, 600, and 900 C. Tritium sorption capacity on Li2TiO3 with additional Li is larger than that on Li2TiO3. At 600 and 900 C, the sorption capacity approximately agrees with the sum of physical adsorption capacity and chemical adsorption capacity, but at 20 and 300 C it is smaller than that. The overall mass transfer coefficient for tritium sorption increases with temperature in the range from 20 to 600 C but it decreases considerably at 900 C. The sorption capacity and the mass transfer coefficient at 600 C for the sample once used in sorption and desorption experiment at 900 C are smaller than that for original ones.
