The purpose of this model report is to describe the evolution of the physical and chemical environmental conditions within the waste emplacement drifts of the repository, including the drip shield and waste package surfaces. This report documents the development of a new process-level model, the near-field chemistry (NFC) model, and develops two abstraction models.
The purpose of this report is to document calculations of the number of waste packages that could be damaged in a potential future igneous event intersecting a repository at YuccaMountain. The analyses include disruption from an igneous intrusion and from an igneous eruption. The analyses also support the evaluation of the potential consequences from a future event as part of the total system performance assessment (TSPA) for the license application for the Yucca Mountain Project.
The purpose of this scientific analysis is to document the results and interpretations of field experiments that test and validate conceptual flow and radionuclide transport models in the saturated zone (SZ) near Yucca Mountain, Nevada. The test interpretations provide estimates of flow and transport parameters used in the development of parameter distributions for total system performance assessment (TSPA) calculations.
Index of Comments on the Draft Environmental Assessment for the Hanford Site
This appendix responds to the issues raised by Federal, State, and local<br/>governments, affected Indian Tribes, private citizens, and other organizations<br/>on the draft environmental assessment (EA) that was prepared pursuant to<br/>Section 112 of the Nuclear Waste Policy Act of 1982 (the Act). In addition to<br/>presenting the issues raised in the comments and the responses, it describes<br/>where changes were made in the final EA.

In February 1983, the U.S. Department of Energy (DOE) identified a<br/>location in Deaf Smith County, Texas, as one of nine potentially acceptable<br/>sites for a mined geologic repository for spent nuclear fuel and high-level<br/>radioactive waste. The potentially acceptable site was subsequently narrowed<br/>to an area of 9 square miles.

The "Nuclear Waste Policy Act of 1982" (NWPA) (42 USC Sections 10101-10226) requires the environmental assessment to include a detailed statement of the basis for nominating a site as suitable for characterization. This detailed statement is to be an evaluation of site suitability under the DOE siting guidelines; the evaluation will be the basis for the comparison of sites reported in Chapter 7.
