Description
A simulation test of radionuclide migration in aquifer has been performed in the Underground Research Facility at CIRP's Field Test Site. 90Sr, 237Np, 238Pu and 241Am were selected as tracers for the test. An undisturbed soil column and the water used in the test were taken from the aquifer in the Facility. During the test hydrodynamic parameters were measured. After 527. 5 day test, the soil column was cut along both longitudinal and radial directions for taking ring-shaped samples, and samples were measured for obtaining the distribution of radionuclide concentration. Testing results were fitted with two dimensional radionuclide migration equation and a release model is proposed by the authors. Testing results evidences that aquifer medium in the Test Site has a strong adsorption ability to 238Pu and 241Am, medial ability to 237Np, and relatively low to 90Sr. Fitted results indicate that the proposed release model is suitable to analyzing the test data
