Effects of meteorological parameters on the intensity of tritium emission from spray cooling ponds

Abstract

An algorithm for estimating tritium emission during the evaporation of water from spray cooling ponds of nuclear power plants is considered. The factors determining the intensity of evaporation and intake of tritium into the atmospheric air are analyzed. For the considered meteorological and technological factors of area source operation, the intensity of tritium emission averages 6.2 Bq/h from each 1·m² of the spray cooling pond area per each 1 Bq/L of specific water activity. The possibility of regulating the emission activity is demonstrated taking into account the data of controlled technological parameters for the water-cooling system of spray cooling ponds and the meteorological parameters of the atmosphere in the NPP location area.
