The US Department of Energy is studying the suitability of Yucca Mountain (YM) as a
potential nuclear waste repository site. Environmental conditions a-e important to
engineered barrier system (EBS) design, materials testing, selection, design criteria,
waste-form characterization, and performance assessment. Yucca Mountain is
located in uninhabited desert which results in an environmental framework
(unsaturated conditions, and sorptive properties of the rock materials) that is
generally favorable for waste disposal. However, waste package (WP) and
engineered barrier system (EBS) design concepts, including materials testing and
selection, design criteria development, waste-form characterization, and
performance assessments all require a specific and detailed understanding of the
environmental conditions that will interact with the WP/EBS. Environmental
conditions assessments from a series of laboratory and modeling studies have been
compiled into a summary report called Preliminary Near-Field Environment Report
(NFER).1 These studies provide the current understanding of the near-field
environmental conditions at YM that not only exist now but will exist in the future.
Because the environmental conditions can change with time, emphasis of the
investigations were on processes and changed (not ambient) conditions.
Quantitative analyses of the actual NFE must incorporate information from EBS
and repository design, operational practices and sequences, and performance
assessmer into environmental assessment models. Also, the NFE depends on1
