Released activity of gaseous tritium at Tsuruga Power Station Unit No. 2 (PWR 1160 Mwe) has been measured with a moisture condensation type monitoring equipment and found to be 2 TBq per year recently.
In power station, natural evaporation of spent fuel pool water has been recognized as the main source of released tritium. However, released activi-ty measured at stack has been about three times as much as estimated activity which is calculated based on concentration and evaporation volume of spent fuel pool water. This discrepancy could be explained by the presence of exchange of water between the pool and the atmosphere.
