Description
Full text: In this study we propose to use tritiated liquid effluents from CANDU type Cernavoda NPP as a tracer, to study dispersion efficiency on Danube-Black Sea Canal. Tritiated water can be used to simulate the transport and dispersion of solutes in Danube-Black Sea Canal because they have the same physical characteristics as water. A study of experimental published formulas was used to determine proper mixing length. Simultaneous measurements in different locations of the Canal confirm the inlet location of the experiment. Another result used in the further experiment concerns the tritium level along the Danube-Black Sea Canal. We measured tritium activity concentration in water sampled along the Canal between July 2002-April 2003. We established tritium level and tritium concentrations significant for the edge and the tail of tritiated wastewater releases. We obtained unit-peak-attenuation (UPA) curve as related to different mixing times using three locations in which we measured tracer-response curves. During the releases of tritiated liquid effluents we determined the slope of the UPA curve, that helped us to model the water movement in observed area of Danube-Black Sea Canal. In this way with a specific software we can predict maximum concentration of soluble pollutant accidental spills in studied area. (authors)
