THE IMPACT OF EXPERIMENTAL PILOT FOR TRITIUM AND DEUTERIUM SEPARATION ACTIVITY ON TRITIUM LEVEL IN THE ATMOSPHERIC WATER VAPOR OF ICSI TRITIUM LABORATORY

Abstract

Results obtained from the monitoring of the ambient air of the ICSI Ramnicu Valcea Tritium Laboratory and the monitoring of the atmosphere around the Experimental Pilot Plant for Tritium and Deuterium Separation are used in the environmental impact evaluation of the experiments in the period 2020-2022.

Even though the experiments carried out involved different tritium activity concentrations, there were no increases in the activity of tritium concentration in the analyzed samples, with numerous results of atmospheric samples being below the detection limit.
