Basalt Waste Isolation Project reference conditions for long-term risk assessment calculations

One of the studies being conducted by the Basalt Waste Isolation Project (BWIP) is an assessment of long-term risks associated with a hypothetical repository located at the Hanford Site. In order to perform such an assessment, it is necessary to develop a set of reference conditions to be used in risk calculations. This document contains the reference conditions to be used during preliminary risk assessment studies. Much of this information is based on field and laboratory data; however, some information is based on assumptions made by technical experts within the BWIP. Before final risk assessments can be completed, these assumptions will be verified by additional field and laboratory studies which are presently under way. 17 refs., 20 figs., 20 tabs
