mm TWS mum is mmm [iiy FOREWORD This report presents the results of one of several waste-management and environmental studies underway or planned for the U.S. Department of Energy's Weldon Spring, Missouri, Raffinate Pits (WSRP) property. As part of a scoping assessment of environmental impacts associated with storage of radioactive materials at the site, this report focuses on the migration of radionuclides contained in materials currently stored in the pits in their existing conditions. The potential benefits associated with engineering improvements that might, be undertaken at the site in the future will be described in a later report, following completion of engineering studies currently being conducted by Bechtel National, Inc. (BNI). This report is not meant to be a definitive statement on the adequacy of the raffinate pits for long-term management of radioactive materials; rather it is meant to analyze, in a rather broad sense, the confinement capabilities of these pits.
