Progress on the U.S. Department of Energy's issue resolution process: A status report

The U.S. Department of Energy (DOE) is studying Yucca Mountain, Nevada, to determine its suitability for a mined geologic repository for high-level nuclear waste. In addition to identifying, clarifying, and resolving technical issues relative to site characterization, DOE has the responsibility to develop a license application for authorization to construct a geologic repository; the license application would be submitted to the U.S. Nuclear Regulatory Commission. In order to assist in managing the complex licensing interactions required, DOE has developed the Issue Resolution process. Issue Resolution provides a means by which any issue, regulatory or technical, can be addressed and clarified. Eight issues are currently active in this process: Erosion, Calcite-Silica, Volcanism, Seismic Hazards, Engineered Barrier System, Disturbed Zone, Substantially Complete Containment, and Ground Water Travel Time. The Issue Resolution organization includes management and staff members with technical and management experience in relevant areas. The Issue Resolution structure has proven to be useful in focusing resources on those areas within the program that need clarification or interpretation and are critical for successful and timely site characterization and licensing of a potential repository
