The Analytical Repository Source-Term (AREST) code is being developed for the US Department of Energy (DOE) as a preliminary performance assessment tool for evaluating waste package behavior in various geologic repository settings. In response to the 1987 amendments to the Nuclear Waste Policy Act of 1982, the code is being enhanced to provide specific assessments of waste package performance in the hydrologically unsaturated welded tuff geology of the candidate repository site at Yucca Mountain, Nevada. Modifications to the code are being made in each of three major functional areas: near-field environment modeling, waste package containment modeling, and waste package release modeling. This paper focuses specifically on the third of these, enhancements to radionuclide release modeling for spent fuel waste packages. 7 refs., 1 fig.
