Integrated radionuclide release: tests and model development (integrated testing)
The Department of Energy's Yucca Mountain Site Characterization Project (YMP) is evaluating a site at Yucca Mountain, Nevada as a potential repository for the disposal of high-level nuclear waste. Credible bounding estimates of the type, concentration, and nature of the radionuclides that might potentially escape the engineered barrier system/near field environment (EBS/NFE) (i.e., the source term) are necessary prerequisites to assessing the expected performance of a po- tential repository. Estimating the source term will require a combination of experimental and modeling tasks that are designed to assess the release of radionclides from the waste form and their transport through and interaction with the components of the EBS/NFE. The Integrated Radionuclidc Release: Tests and Model Development activity (Integrated Testing) at Lawrence Liver-more National Laboratory (LLNL) is an experimental and modeling activity that is specifically concerned with radionuclide transport through and interaction with the compo- nents of the EBS/NFE. As such, this activity is the link b!etween waste-form degradation activities and far-field transport activities. Performance analysis of the EBS/NFE subsystem is an important component of the total system performance analyses (TSPA) that will be used to evaluate reposi- tory performance.
