Performance Assessment of the US Ecology Site, Richland Washington

Description

Develop a model to quantitatively evaluate past and long-term performance of the U.S. Ecology Low-Level Radioactive Disposal Facility in Richland Washington in support of the Environmental Impact Statement and evaluation of closure alternatives. Model development included a source emplacement and release model, transient vadose zone flow and transport model, and an aquifer transport model to calculate radionuclide concentrations in the underlying aquifer. Perl scripts were developed to perform Monte Carlo uncertainty analysis of predicted concentrations and radiological doses.
