Technical basis for high-level waste repository land control requirements for Palo Duro Basin, Paradox Basin, and Richton Dome

Technical Report ·
OSTI ID:6756887
;

Three sites, the Palo Duro Basin in Texas, the Paradox Basin in Utah, and the Richton Dome in Mississippi, are being investigated by the US Department of Energy for high-level radioactive-waste disposal in mined, deep geologic repositories in salt. This report delineates the use of regulatory, engineering, and performance assessment information to establish the technical basis for controlled area requirements. Based on the size of the controlled area determined, plus that of the geologic repository operations area, recommendations of possible land control or ownership area requirements for each locale are provided. On a technical basis, the following minimum land control or ownership requirements are recommended, assuming repository operations area of 2240 ac (907 ha), or 3.5 mi/sup 2/ (9.1 km/sup 2/): Palo Duro Basin - 4060 ac (1643 ha), or 6.3 mi/sup 2/ (16.4 km/sup 2/); Paradox Basin - 4060 ac (1643 ha), or 6.3 mi/sup 2/ (16.4 km/sup 2/); and Richton Dome - 5000 ac (2024 ha), or 7.8 mi/sup 2/ (20.2 km/sup 2/). Of the factors used to determine the technically based recommendations, one was found to dominate each locale. For the Palo Duro and Paradox Basins, the dominant factor was the need to limit potential radionuclide release by ground-water flow to the accessible environment. For the Richton Dome, the dominant factor was the need to limit the potential effects of solution mining on dome and repository integrity.
