Research and development of technologies for the safe handling of high-level tritium are indispensable for realization of a thermonuclear fusion reactor, and tritium measurement techniques play an important role in this subject. More than 35 years have been spent for the studies in this field at the Hydrogen Isotope Research Center (HRC), University of Toyama. Nuclear fusion systems need new measurement techniques that work in the limited range of conditions with high tritium level, as well as at the environmental level, because nearly pure tritium is used as fuel particles in the fusion system. Therefore, new measurement techniques have been investigated so far at HRC, and some of them have already played a certain role in the research on tritium-material interactions, but they are not enough yet. Further studies on measurement techniques will be required to establish the ability for precise control of concentration, amount, and/or distribution of tritium under various conditions.
