| Research Abstract |
Deuterium permeation characteristics were determined for composite membranes used in transmutation reaction by deuterium permeation. Higher deuterium gas pressure resulted in higher yield of transmutation. Surfaces of electrochemically deuterium-permeated samples were analyzed by SIMS and ICP-MS. Peaks of Mass number 139, 140, 141, 142 were clearly observed in deuterium-permeated samples with 133Cs implantation. Peak of mass number 190 was observed in deuterium-permeated samples with W implantation.
