The rate of tritium release from Li2TiO3pebbles was examined by post irradiation thermal desorption spectroscopy (the Temperature Programmed Desorption (TPD) method). Pre-treatments before and even after irradiation were found useful to gain insight on the behavior of these pebbles at different temperatures, as good spectrum de-convolution is achieved and kinetic parameters for the rate determining pseudo-first-order steps can be estimated. We show the results concerning Li2TiO3pebbles bed specimens developed in the frame of the European fusion technology program. © 2003 Elsevier Science B.V. All rights reserved.
