Abstract: A MATHEMATICAL MODEL FOR RADIONUCLIDE TRANSPORT IN SINGLE FRACTURED GRANITEⅠ.ANALYTICAL SOLUTION FOR A CONTINUOUS INJECTION EXPERIMENTLi Chunjiang(China Institute of Radiation Protection,Taiyuan 030006)Yang Tianxing(Changchung Science & Technology University,Changchung 130006)ABSTRACTThe mathematical model of radionuclide transport in the saturated fractured porous granite is obtained,and the analytical solution of concentration distribution in the contiuous steay state in both fracture and rock matrix is also obtained for Dirichlet boundary conditions. The main effect of the transport of radionuclide in single fracture channel is described.Key words Granite Single fracture Radionuclide transport Mathematical model
