| 英文摘要 | This annual report describes research conducted in FY1989 by Los Alamos National Laboratory in the Hydrology/Radionuclide Migration Project. This work, which is done in coordination with several other organizations, relates to the movement of radionuclides underground at the Nevada Test Site. This project continues the long-term monitoring of tritium and fission product concentrations in water at the Cambric study area. As water has been pumped from an adjacent well, radionuclide concentrations in the cavity region have diminished to near the limits of detection. Neutral and anionic radionuclides have been measured in the effluent of the pumped well, but cations such as {sup 90}Sr and {sup 137}Cs have not been detected. This year a study was initiated to measure the spatial distribution of refractory and volatile elements in the cavity/chimney regions of underground nuclear tests. Differences in both distribution and leachability were observed for the two sites studied. Colloidal material from the Cambric site was collected and analyzed by transmission electron microscopy. We believe we were able to distinguish natural colloids from those introduced in drilling fluids. We tested the hypothesis that the {sup 87}Sr/{sup 86}Sr isotopic ratio would be useful in making this distinction and concluded that it was not. We reported a first measurement of {sup 99}Tc in water from the Cambric site. We also participated in the hydrologic study of a highly pressurized zone in the tuff aquifer at the Nevada Test Site that was apparently created by nuclear testing. 25 refs. |
