چکیده
|
The selection of appropriate transport parameters of radionuclides is of utmost importance in safety assessment of radioactive waste disposal site# the safety assessment of waste disposal requires the measurement of transport parameters of radioactive nuclides in the soil around the disposal site# in this paper, the transport parameters of cobalt nucleus in the naeein disposal soil were measured using two static (batch) and dynamic (column experiment) methods# in the static method, the distribution coefficient was determined by performing batch adsorption experiments, and then the retardation factor for the soil disposal was calculated# in dynamic method, first, the breakthough curve for cobalt was determined experimentally# then, by fitting a curve to the experimental data (using stanmod software), the distribution coefficient parameters and the retardation factor for cobalt were extracted# the distribution coefficient ( ) and retardation factor (r) for cobalt were 12#39 lit / kg and 58 respectively#by comparing these results with the results obtained from the static method (20 lit / kg for and 93 for r), it was concluded that there is a nearly two times difference between the results obtained by static and dynamic measurement methods#
