Described are the analytical methods and results used to determine the migration of actinides in a flowing-groundwater laboratory-simulation of a basalt repository for high-level nuclear waste. The radiochemical methods developed and employed to measure actinide activities in groundwater samples and component surfaces include the use of gamma, X-rays, and alpha spectroscopy, with associated preparation and calibration. These methods include double isotope spiking with Np-235 and Pu-236 for determination of Np-237 and Pu-239 in groundwater, gamma-spectroscopic measurements of rock surfaces for spatially profiling neptunium activity, and a leaching procedure for quantitating the actinide activities on those rock surfaces.
