Ten years3H survey at the Krško Nuclear Power Plant

As part of the general off-site radioactivity monitoring at the Krško Nuclear Power Plant, tritium is measured in the water of the river Sava at two locations (one upstream reference point and downstream point of total dispersion), the inlet and discharge of the essential plant service supply water, in four borehole waters, in tap water in Krško and Bre zice, and in precipitations at four points. Since 1992 tritium has also been analysed in gaseous effluents in the exhaust stack. Tritium is electrolytically enriched and determined by a liquid scintillation technique. For liquid effluents an average normalized release of 17.6 TBq per GW_e·y was obtained, while this value for gaseous effluents is 2.3 TBq per GW_e·y.
