Regional Geology: GIS Database for Alternative Host Rocks and Potential Siting Guidelines

The objective of this work is to develop a spatial database that integrates both geologic data for alternative host-rock formations and information that has been historically used for siting guidelines, both in the US and other countries.  The Used Fuel Disposition Campaign (UFDC) is considering three alternative geologic host rocks for mined repositories (granitic / crystalline, salt, and clay / shale) and crystalline basement rock for deep borehole disposal.  This report documents progress in populating a GIS Database with information concerning the distribution of alternative host rock formations in the US, and of information related to potential siting guidelines that could impact site screening and site evaluation.
