Extensive work has been carried out by the U.S. Department of Energy (DOE) in the development of a proposed geologic repository at Yucca Mountain (YM), Nevada, for the disposal of high-level radioactive waste. In support of this development and an associated license application to the U.S. Nuclear Regulatory Commission (NRC), the DOE completed an extensive performance assessment (PA) for the proposed YM repository in 2008. This presentation describes uncertainty and sensitivity analysis results for the nominal scenario class (i.e., for undisturbed conditions) obtained in the 2008 YM PA. The following topics are addressed: (i) uncertainty and sensitivity analysis procedures, (ii) drip shield and waste package failure, (iii) engineered barrier system conditions, (iv) radionuclide release results for the engineered barrier system, unsaturated zone, and saturated zone, and (v) dose to the reasonably maximally exposed individual specified in the NRC regulations for the YM repository. The present article is part of a special issue of Reliability Engineering and System Safety devoted to the 2008 YM PA; additional articles in the issue describe other aspects of the 2008 YM PA.
Uncertainty and sensitivity analysis are fundamental components of the 2008 performance assessment (PA) conducted by the U.S. Department of Energy (DOE) for a proposed high-level radioactive waste repository at Yucca Mountain (YM), Nevada  and . The following presentation describes uncertainty and sensitivity analysis results obtained for the nominal scenario class  in the 2008 YM PA. Additional presentations describe uncertainty and sensitivity analysis results obtained in the 2008 YM PA for early failure scenario classes  and , igneous scenario classes  and , seismic scenario classes  and , and all scenario classes collectively . The following topics are considered in this presentation: uncertainty and sensitivity analysis procedures (Section 2), drip shield (DS) and waste package (WP) failure (Section 3), engineered barrier system (EBS) conditions (Section 4), radionuclide release results for the EBS, unsaturated zone (UZ) and saturated zone (SZ) (Section 5), and dose to the reasonably maximally exposed individual (RMEI) (Section 6). The presentation then ends with a summary discussion (Section 7).
