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.
