JAEA has been conducting the Instructor Training Program (ITP) since 1996 under the auspices of MEXT to contribute to human resource development in currently 11 Asian countries in the field of radiation utilization for seeking peaceful use of nuclear energy. ITP consists of Instructor Training Course (ITC), Follow-up Training Course (FTC) and Nuclear Technology Seminars. In the ITP, trainings or seminars relating to technology for nuclear utilization are held in Japan by inviting nuclear related people from Asian countries to Japan and after that, the past trainees are supported during FTC by dispatching Japanese specialists to Asian countries. News Letter is also prepared to provide the broad range of information obtained through the trainings for local people near NPPs in Japan. The present report describes the activities of FY2014 ITP and future challenges for improving ITP more effectively.

Times Cited Count：9 Percentile：36.09(Physics, Condensed Matter)The pressure-induced disproportionation reaction of LaH was investigated by infrared reflection and Raman measurements at ambient temperature. The relative reflection intensity began to decrease significantly at a pressure of about 12 GPa and fell to 10% of the initial value at 20 GPa. Absorption peaks at pressures above 14 GPa were assigned to the hydrogen vibrations at the tetrahedral and octahedral sites of the fcc metal lattice, respectively. These infrared results indicated insulating LaH
precipitated from metallic LaH.

We have investigated the structural and electronic properties of rare-earth metal di-hydrides under high pressure. Rare-earth metal di-hydrides exhibit the fcc metal lattice, which contains hydrogen atoms in only tetrahedral interstitial sites. It is expected that the hydrogen atoms transfer to another interstitial site, such as an unoccupied octahedral site, by compression of metal lattice. We found the pressure-induced phase separation of yttrium di-hydride and lanthanum di-hydride. These results suggest that the disproportionation reaction into solid-solution and tri-hydride phases occurred under high pressure. In order to demonstrate the disproportionation reaction, we have performed infrared reflection spectroscopy for lanthanum di-hydride under high pressure and have found the formation of an insulating phase.
