Long-Term Site Management Plan for the LLRW (Low-Level Radioactive Waste) Disposal Area at West Valley, New York: Task 3: Final Report.

摘要

The New York State Energy Research and Development Authority has sponsored a project to develop an integrated set of site management plans for the West Valley low-level radioactive waste (LLRW) disposal area. The plans were directed to upgrade the disposal area so that passive custodial care and monitoring activities would be sufficient to protect public health and safety and the environment. Task 3 Long-Term Site Management Plan, is the subject of this report. The goal of Task 3 was to select a long-term site management plan that would result in a stabilized site which would require only passive maintenance activities. The objectives of Task 3 were to formulate and evaluate alternative long-term strategies. The following seven system plans were conceptualized for a comparative assessment: Precast Concrete Vault, Structural Glacial Fill cover, Structural Clay Cover, Dynamic Compaction with a Semi-Structural Clay Cap, Displacement piles with a Semi-Structural Clay Cap, Grouting with a Semi-Structural Clay Cap, and Active Maintenance/Final Closure with a Semi-Structural Clay Cap. The Energy Authority's basis for selecting its preferred alternative is described. Based upon this chosen alternative, a scale model demonstration project is presented to test some of the engineered remediation techniques. 53 refs., 20 figs., 18 tabs. (ERA citation 13:050805)
