Simulation of radionuclides in the saturated zone at the E-Area low- level radioactive waste disposal facility, Savannah River Site
- Westinghouse Savannah River Co., Aiken, SC (United States)
Numerical simulation of migration of Technetium-99 and Tritium beneath a proposed low-level radioactive waste disposal facility at the Savannah River Site was conducted utilizing the Porflow code. These species were selected for preliminary analysis based upon screening exercises designed to identify species of concern and because each has contrasting properties in regard to adsorption and half-life. Numerous field data describing the three-layered aquifer system were utilized to set up the model and for comparison to simulated results to achieve calibration. Results of initial simulations indicate that contaminants migrate laterally toward discharge zones at local streams. Vertically the Technetium-99 plume reached the lowermost aquifer in one small area in the vicinity of the surface water discharge zone. Maximum simulated radionuclide concentrations were reached at different times and locations but were both below levels that would pose a health threat to either the general public or inadvertent intruders.
