This is the case of the DCLL blanket or the WCLL, where the solubility and diffusivity values will affect to the induced tritium flux in terms of magnitude and kinetics. However, there exists a huge band in the literature for the results obtained experimentally for the solubility of the isotopes in the mentioned liquid metal alloy, which is unacceptable from the designing point of view. Moreover, the exact content of lithium and the impurities that the PbLi alloy may contain seems to be another key issue that needs to be faced. This work shows the preliminary results obtained in a new measurement campaign carried out with samples of PbLi qualified in terms of impurities and lithium content. These samples have been tested in the Absorption-Desorption facility of the UPV/EHU that has been recently repaired and upgraded as part of EUROfusion program in collaboration with CIEMAT. 收起
