Title: Environmental monitoring of the tumulus low-level waste disposal facilities at Oak Ridge National Laboratory

Conference ·
OSTI ID:6755663

The tumulus facilities at Oak Ridge National Laboratory (ORNL) were constructed beginning in 1987 as a means of above-grade disposal of low-level radioactive waste (LLW). The facilities consist of Tumulus I, Tumulus II, and the Interim Waste Management Facility (IWMF). They are designed to meet performance criteria that require no release of radioactive contaminants to the environment for a period of one hundred years. This paper describes the tumulus facilities, the environmental monitoring program, and what we have learned from the program over approximately three years of operation. Our data suggest that the tumulus facilities are an effective means of disposal of low-level radioactive waste. However, problems with high pH and the leaching of [sup 40]K, and potentially other elements from the concrete disposal pads and vaults, need to be addressed with regard to the long-term performance of the facilities.
