Borehole Assessment Needs Plan

This report describes the methodology and results of a study performed by The Analytic Sciences Corp. (TASC) for the Basalt Waste Isolation Project (BWIP). The objective of the work was to provide an independent evaluation of needs for additional boreholes as part of the BWIP Site Characterization activities. Basic strategy evaluates the contributions of additional boreholes to confidence that relevant EPA, NRC and DOE performance criteria can be met. The technical approach consists of a criteria and data review, a statistical analysis of borehole data using Kriging techniques, and an evaluation of BWIP repository performance for selected scenarios. 30 refs., 7 figs., 15 tabs.
