The Yucca Mountain Performance Confirmation program consists of tests, monitoring activities, experiments, and analyses
to evaluate the adequacy of assumptions, data, and analyses that form the basis of the conceptual and numerical models of
flow and transport associated with a proposed radioactive waste repository at Yucca Mountain, Nevada. The Performance
Confirmation program uses an eight-stage risk-informed, performance-based approach. Selection of the Performance
Confirmation activities (a parameter and a test method) for inclusion in the Performance Confirmation program was done
using a risk-informed performance-based decision analysis. The result of this analysis and review was a Performance
Confirmation base portfolio that consists of 20 activities. The 20 Performance Confirmation activities include geologic,
hydrologic, and construction/engineering testing. Several of the activities were initiated during site characterization and are
ongoing. Others activities will commence during construction and/or post emplacement and will continue until repository
The Yucca Mountain Project (YMP) is a scientific study by the U.S. Department of Energy (DOE) to evaluate the potential
for geologic disposal of high-level radioactive waste in an unsaturated-zone desert environment. The Performance
Confirmation -(PC) program consists of tests, monitoring activities, experiments, and analyses to evaluate the adequacy of
assumptions, data, and analysis that form the basis of the conceptual and numerical models of flow and transport at Yucca
Mountain. The PC program is designed to test whether: 1) the actual subsurface conditions encountered are as anticipated, 2)
any changes in these conditions during construction and waste emplacement are within expected limits, and 3) the natural and
engineered systems are functioning as intended.
