The DOSTOMAN code calculates compartment inventories of radioactivity for all model compartments defined. Calculations are performed for the entire period of time simulated, at user-designated intervals. This output permits tracking of radionuclide movement within and from the disposal site. Simulation runs were performed for /sup 60/Co, /sup 90/Sr, /sup 137/Cs, /sup 239/Pu, and /sup 241/Am for the duration of the site's operational period. For calculational purposes only, this period was assumed to extend to the year 2093. Sensitivity analyses, in which the relative importance of biotic and abiotic transport processes in radionuclide migration was evaluated, were performed for the EDS and CDS models. Interactive effects between transport processes were examined, as were time-dependent changes in process sensitivities. Results of the analyses are useful in defining the adequacy of present environmental monitoring activities. The current monitoring program addresses all pertinent environmental media. The level of comprehensiveness in sampling each medium, however, does not reflect differences in importance of the various transport processes. A number of special studies, in progress or planned, are expected to aid in improving the monitoring program. Limitations of the DOSTOMAN model, as applied to the Radioactive Waste Management Complex, are discussed. Modeling of atmospheric and hydrologic dispersion of contaminants, and consideration of seasonal dynamics of transport processes, are identified as most deserving of attention. It is recognized that, to the extent that further refinements of the monitoring program are based on model projections, resolution of these limitations is important. Recommendations are offered for work needed to deal with these limitations, many of which are already planned for implementation.
