The purpose of this analysis report is to document the screening decisions and technical bases for inclusion or exclusion of each FEP identified as relevant to the TSPA and the Yucca Mountain disposal system, in accordance with the regulatory screening criteria identified for the Yucca Mountain Site. The companion report, Features, Events, and Processes for the Total System Performance Assessment: Methods (SNL 2008 [DIRS 179476]) documents: (1) the origin, and the methods used in the development of a comprehensive list of FEPs that could potentially affect the postclosure performance of the Yucca Mountain disposal system; (2) the methodology and guidance used to screen FEPs for inclusion or exclusion from TSPA; (3) the methodology and guidance used to create scenario classes; and (4) compliance with NUREG-1804 (NRC 2003 [DIRS 163274]) acceptance criteria. The screening decision results presented in this report are reflected in the current performance assessments (or TSPA) described in Total System Performance Assessment Model/Analysis for the License Application (SNL2008 [DIRS 183478]).
Performance assessment is required to demonstrate compliance with the postclosure performance objective for the DOE YMP as stated in proposed 10 CFR 63.2 (70 FR 53313 [DIRS 178394]) and in 10 CFR 63.2 [DIRS 180319]. A performance assessment is an analysis that:
1. Identifies the features, events, processes (except human intrusion), and sequences of events and processes (except human intrusion) that might affect the Yucca Mountain disposal system and their probabilities of occurring;
2. Examines the effects of those features, events, processes, and sequences of events and processes upon the performance of the Yucca Mountain disposal system; and
3. Estimates the dose incurred by the reasonably maximally exposed individual, including the associated uncertainties, as a result of releases caused by all significant features, events, processes, and sequences of events and processes, weighted by their probability of occurrence.
