| The Department of Energy (DOE) must remediate nuclear waste under the regulatory requirements of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The DOE requires a model, which incorporates Life Cycle Costs, Implementability, Short and Long-term Effectiveness, and Reduction of Toxicity, Mobility or Volume, to be used in the selection of the remedy. Our research focused on the development risk of nuclear waste remediation alternatives at the Idaho National Environmental Engineering Laboratory (INEEL). We developed a decision and risk analysis model to evaluate In-Situ Vitrification (ISV) remedial alternatives. We evaluated the ISV remedial alternatives based on the CERCLA criteria and technical development risk. The risk analysis revealed that some of the ISV alternatives were susceptible to events that could impact successful implementation. Recommendations were made as to how to reduce the identified development risks. |
