| The Application of CFC to the Groundwater Study in the Potential Repository Site for China''''s High Level Radioactive Waste Disposal |
| CFCs are effective tools in the study of groundwater dating. In this paper, the method and principles of CFC compounds as groundwater dating tools are described, and the actual application of the method to hydrogeological research in the Beishan Potential Repository Site in Gansu Province for China's High Level Radioactive Waste Disposal is reported. The results indicate that the CFC age of shallow groundwater located in valley and depression is mainly from 15 to 26 years and the shallow fracture water is mostly mixed water of young CFC_containing water and old CFC_free water. Based on the description of the method for determination of mixing ratios, the mixing ratios of groundwater in the study area are calculated from the CFC concentration of groundwater samples. In comparison with tritium, CFC seems to be a better tool which possesses more advantages for young groundwater dating at present. |
