This is a semi-annual status report on the results of research conducted on behalf of the US Nuclear Regulatory Commission by the Center for Nuclear Waste Regulatory Analyses (CNWRA) in support of activities under the Nuclear Waste Policy Act, as amended. Nine specific projects are under way as reported here. The Geochemistry Project staff is using laboratory methods and computer calculations to assess key geochemical constraints and to evaluate sorptive properties of zeolites present at the proposed repository site. The Thermohydrology Project has as its focus improved understanding of heat and fluid flow in unsaturated media. Laboratory, field, and calculational studies are combined in the Seismic Rock Mechanics Project to examine the effects of repeated seismic loadings on the rock-mechanical and hydrological responses of rock masses. The Integrated Waste Package Experiments have been initiated to evaluate degradation modes of candidate waste container alloys. Three-dimensional computer analysis techniques are being used to investigate spatial variability of flow and transport in variably saturated fractured porous media in the Stochastic Flow and Transport Project. The Geochemical Analogs Project staff seeks to investigate the role of such analogs in the licensing process, and is currently focused on characterizing and evaluating two potential sites for investigation. The Sorption Modeling Project has as its objective the evaluation and eventual selection of model(s) of sorption processes which are deemed technically acceptable in the context of repository licensing. The Performance Assessment Project is directed toward developing and evaluating methodologies for evaluation of the long-term performance of the proposed repository. Finally, in the recently initiated Volcanism Project, a comprehensive evaluation of the state of knowledge regarding volcanism in the basin and range province has been completed.
