Abstract

A large reprocessing plant of spent nuclear fuel is now under construction in Rokkasho-village, Aomori Pref. Japan. We carried out the survey of tritium concentration in water vapor and precipitation on the top of Mt. Hakkoda, to grasp the behavior of tritium in the environment of Aomori Pref. The tritium concentration in water vapor and precipitation tended to increase from spring through summer. Deuterium concentration in water vapor is lower than precipitation and the effect of the isotope separation by evaporation was observed. The tritium concentration in water vapor, however, is a little bit higher than precipitation. The tritium concentration in water vapor showed the similar change on the top of Mt. Hakkoda and also the wide region covering Rokkasho-village from Aomori-City. Also, on the top of Mt. Hakkoda the correlation was observed between the tritium concentration in water vapor and ozone concentration.
