Authors:   Ekidin А., Antonov К., Vasiljev А., Vasyanovich М., Pyshkina М., Kuryndin A., Shapovalov A., Antushevskiy А., Semenov М., Murashova Е. , Kapustin I., Philatov I. Issue:   3(85) – 2017.

The article provides results of assessment of airborne radiological releases of tritium from spray cooling ponds of Balakovo NPP during cold season. The differences in conditions of generation of tritiated water cloud near the surface of spray cooling ponds between cold and warm seasons are demonstrated. The results of comparison of reasonable approaches for assessment of intensity of tritium discharge from spray cooling ponds are provided as well. The issues of accumulation of tritium in snow cover near Balakovo NPP are addressed and demonstrated in article. Results of conservative assessments of radiological impact of the tritium discharges show that Balakovo NPP spray cooling ponds are source for which discharge limits shall be set and properly controlled.
