W samples were irradiated with 4.8 MeV W ions to 0.65 and 12 dpa, and a thin Pd layer was deposited on the sample with the higher damage level by a technique of sputter-deposition. Then, the samples were exposed to DC glow-discharge D plasma at 403 K. In spite of the higher damage level, the concentration of trapped D in the damaged zone of the Pd-covered sample was far smaller than that in the non-covered one. The small D retention in the Pd-covered sample was explained by a decrease in the D concentration in the solution state owing to the enhanced recombinative release by Pd and the consequent reduction in the occupation probability of radiation-induced traps. These observations indicated that tritium inventory in neutron-irradiated W materials can be significantly reduced by enhancement of tritium reemission by surface modifications., Article, 富山大学水素同位体科学研究センター研究報告, 32巻, 2013.05.31, pp.9-20}, pages = {9--20}, title = {照射損傷を受けたタングステン中の重水素滞留挙動に及ぼすPd表面被覆の影響}, volume = {32}, year = {2013} }
