【 摘 要 】

Lithium is used frequently as a surrogate for cationic radionuclides such as NpO2 + in field and laboratory settings. Current plans include the use of Li + as a reactive tracer in field tracer testing in the saturated alluvium south of Yucca Mountain, NV, site of a potential high-level nuclear waste. Characterization of the alluvial material for grain size, mineralogy, cation exchange capacity (CEC), and surface area yields data that is compared with lithium batch sorption as a first step in inferring radionuclide transport behavior. This research will be used to help assess performance of the potential repository.
