This paper describes the process of preparing a feasibility study (FS) for remediation of a low-level radioactive waste (LLW) disposal site at Oak Ridge National Laboratory (ORNL). ORNL conducts research and development and is one of three DOE-owned facilities on the Oak Ridge Reservation (ORR). Waste Area Grouping (WAG) 6 is located in Melton Valley, approximately 2 miles southwest of the plant in Roane County, Tennessee. WAG 6 includes Solid Waste Storage Area (SWSA) 6, which is still used for shallow land burial of LLW and nonradioactive materials and was the primary focus of the FS. SWSA 6 covers 68 acres, 19 of which contain wastes such as low-level radioactive liquids, solids, sludges, asbestos, and biological and associated laboratory wastes. During the first 15 years of operation, the site also received chemical wastes, but since 1986, it has been used only for LLW. Until 1986, wastes were placed in unlined trenches and auger holes, but since then, wastes have been disposed in greater confinement disposal silos, lined pipe wells and auger holes, and above-ground tumulus units. A list of the sitewide alternatives initially developed for WAG 6 remediation is presented. The alternatives combined capping, structural stabilization (dynamic compaction/grouting), waste consolidation, and groundwater collection/treatment components. In situ vitrification was also considered for areas with significant long-life source inventories.
