Establish a field location and install a 10-year field experiment to simulate and study the movement of radionuclides through an artificial vadose zone. The general objectives of the study are to: 1. Identify and quantify key long-term (10 year) radiological geochemical and transport phenomena under field vadose zone conditions. 2. Identify coupled (interacting) long-term processes that are not evident in short duration laboratory experiments. 3. Reduce uncertainty and improve technical justification for selection of geochemical conceptual models in various facility Performance Assessments (PA).
