ABSTRACT

In this work, tritium concentration was determined in different D₂O enrichment in heavy water samples. Samples were prepared from Arak Heavy Water Production Plant. Tritium concentration was determined utilizing liquid scintillation detector (LSC) system based on β-decay of tritium isotope. In this work instead of simple distillation, the azeotropic distillation method was used. Absorbed spectra and fluorescence spectra were registered by Shimadz spectrometer UV-2100 model and fluorescence spectrometer LS50B model respectively. Tritium concentration was obtained from 1.75 ± 0.80 up 6.16 ± 1.01 Bq/L for 0.35% to 77.50% enrichment of D₂O concentration in heavy water samples. Coefficient correlation between tritium concentration and D₂O concentration in heavy water R² = 0.853 was derived. For 99.8% enriched D₂O in heavy water, deviation was observed from direct line that caused decreasing of R².
