As part of the general off-site radioactivity monitoring at the Krsko Nucle
ar Power Plant, tritium is measured in the water of the river Sava at two l
ocations (one upstream reference point and downstream point of total disper
sion), the inlet and discharge of the essential plant service supply water,
in four borehole waters, in tap water in KrSko and Brezice, and in precipi
tations at four points. Since 1992 tritium has also been analysed in gaseou
s effluents in the exhaust stack. Tritium is electrolytically enriched and
determined by a liquid scintillation technique. For liquid effluents an ave
rage 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.
