Fifty-four objectives were identified to guide the screening of the Nevada Research and Development Area of the Nevada Test Site for relatively favorable locations for the disposal of nuclear waste in a mined geologic repository. The objectives were organized as a hierarchy composed of 4 upper-level, 12 middle-level, and 38 lower-level objectives. The four upper-level objectives account for broad national goals to contain and isolate nuclear waste in an environmentally sound and economically acceptable manner.

The primary goal of the ongoing LLL program is to develop the technology and data base required to license a nuclear repository in a crystalline rock medium, located at or near the Nevada Test Site (NTS). Our secondary goal is to apply this technology in helping the Department of Energy (DOE) develop repositories in other media and locations.
