This report presents an analysis of the long-term structural and radiological performance of a hypothetical abovegrade earth-mounded concrete vault used for the disposal of low-level radioactive waste. The vault structure design is based on the application of accepted standard engineering codes. The degradation of the concrete vault and the grouted waste forms over time and the resultant changes in the leaching and migration of radionuclides through the environment are modeled using a combination of the HELP, BARRIER, PATHRAE, and PRESTO-CPG computer codes. The resultant radiological doses to a farmer living adjacent to the facility and to several types of inadvertent intruders are calculated. These calculations show the performance of this total-system treatment and disposal concept to greatly exceed the Department of Energy's performance objectives for the protection of the general public and inadvertent intruders. 12 refs., 9 figs., 3 tabs.
