Two papers presented in this session cover a numerical simulation of radionuclide migration from Savannah River Site`s E-Area Vaults (EAV) to the groundwater. These vaults are constructed below the ground surface and above the historical high water table. This paper covers the simulation of radionuclide migration in the unsaturated zone. A saturated zone model containing aquifers affected by the facility was also developed. The rate (Curies/yr) of radionuclide release to the water table obtained from Part I was used as the source term for the saturated zone model. The migration of 23 key radionuclides for up to two million years was predicted [Westinghouse 1994]. The calculated annual dose of each of the radionuclides due to ingestion of water, based on unit initial inventory, is reported in Part II.
