Abstract
Research and development at the Hydrogen Isotope
Research Center of Toyama University in the last nine years are briefly
reviewed by focusing attention on technological developments and topics
of fundamental research. This paper describes technological developments
in tritium measurement by bremsstrahlung counting, tritium gettering by
Zr-based alloys, gas chromatographic hydrogen isotope separation and hydrogen
energy conversion by Ni-hydride battery. The topics of fundamental research
are material interactions taking place on the first wall of tokamaks, isotope
effects on hydrogen absorption by Pd-Pt alloys, radiochemical effects of
β-rays on tritium oxidation in gas phase and internal hydride formation
of Mg-Ⅲa alloys. It is pointed out that hydrogen-material interactions
must be understood in more detail so as to develop new energy systems using
hydrogen isotopes as fuel by nuclear fusion and chemical reactions.
