A MATHEMATICAL MODEL FOR RADIONUCLIDE TRANSPORT IN SINGLE FRACTURED GRANITE Ⅱ.ANALYTICAL SOLUTION FOR A PULSE INJECTION EXPERIMENT

The mathematical model of radionuclide migration in single fractured granite is studied under saturated flow and pulse injection. The analytical solutions of concentration distribution in fracture and rock matrix are given. By analyzing the breakthrough curves of concentration eluting from single fracture, the relative parameters are obtained. The main factors affecting these parameters are also described.
